8th Gen Civic - Concerns on fuel economy

[Arcturus]

I'm looking at purchasing a VTI-L very soon, and one of the factors that influenced my decision was its fuel economy (compared with its competitors in Mazda 3 and Toyota Corolla). Honda lists the VTI/VTI-L manual economy figure at 6.9l/100km. I understand that these figures are likely to be higher, but many of the reviews I read mentioned that the Honda figure was very close (real-world perhaps more like 7.1). I've seen many around here indicate a MUCH higher figure, even after breaking the engine in - figures like 9 - 12l/100km are very disheartening.

I'm coming from a 93 EB Ford Falcon with LPG fitted, so I understand the Civic's economy won't match LPG, but it shouldn't be that big of a difference. I get around 350km on a 60 litre tank of LPG, Civic owners are saying they get around 400km on a 50 litre tank of ULP (a much more expensive prospect).

Can anyone shed light on this? I was under the impression the Civic was one of the best cars in terms of fuel economy (for the price).

[simonnowis]

really depends on how you drive whether you floor it or not, but just for everyday normal driving the fuel economy is pretty good. it is def not 12/100km. it more like 7-7.5/100km maybe. anyway you wont go wrong with fuel economy. but i the 8th gen seems to have a few factory problems, one of them is the driver side window stuffing up. however honda will fix it with your warranty. people on hear have listed alot of other problems to which i have not experienced except window problems. if your able to deal with these issues, the civic is a nice car for you.

[yourfather]

driving habits can increase your consumption up to 40%.

it is one of the best cars for fuel economy, but you need to learn how to drive economically.

with my integra, I can get 350 for a tank or 500, depending on how i drive.

[denot]

i used around 9-10/100k with my Sports (Auto) and its a mix of city & highway drive...

[[[d a n n y]]]

firstly LPG equipped cars do consume the same amount of fuel or even more.
but the LPG itself is cheaper so it may seem so.
the civic is a very fuel economic car
in the end it depends how u drive your car

[Arcturus]

];1219360']firstly LPG equipped cars do consume the same amount of fuel or even more.

Yes I realise that, i'm just comparing the $/litre ratio, which is obviously more important when looking at different fuel systems. I can travel about 350km for under $30 (60 litre tank based on LPG prices on < 50cents/litre). I'd be interested in knowing how far people can travel on ULP. It seems to be around 400-450km for around $65 (50 litre tank on approx $1.30/litre), so a fair amount more compared to my LPG tank.

[yourfather]

costs me about a dollar a kilometre.

[Arcturus]

err, you sure about that?

[andyhui01]

here is mine everysince I started recording, (2006 Honda Civic VTi-L Auto), no modifications.

http://www.phyrefile.com/pic/2007/06/17/fuel.JPG

you can see it varies alot, I believe the first tank was 80&#37; in the city, 20% highway or less.

[Hans Bond]

let's take the worst case scenario..

an 8th gen civic can give you 8/100k (in facts it can vary if you do the city driving, you can get up to 10/100k)
while the lpg-fitted car can give you 15/100k

so

if you need to do 100k, the civic will cost you:
the civic will cost you: 8 litres x $1.25 = $10
while the lpg-fitted car will cost you: 15 litres x $0.50 = $7.50

Conclusion:
there is NO way you can beat the lpg...only toyota prius with its hybrid machine can match the lpg so far.

[denot]

there is NO way you can beat the lpg...only toyota prius with its hybrid machine can match the lpg so far.

not even Civic Hybrid? Dang!!!

[Arcturus]

there is NO way you can beat the lpg...only toyota prius with its hybrid machine can match the lpg so far.

I realise that, but i'm happier with your figures of 8/100km. I'm more concerned about these figures of 10/100km.

[NeoNode]

I think you're better off buying a diesel car if you're THAT concerned about fuel economy.

Although the only thing that I can think of being the small Polo TDI lol.

[Hans Bond]

I have to admit the technology behind the prius beats the civic hybrid, they even have less fuel consumption than civic hybrid.


not even Civic Hybrid? Dang!!!

[Arcturus]

I think you're better off buying a diesel car if you're THAT concerned about fuel economy.

I would if I could, nothing really in my price range or specifications. I'm just wondering why many reviews suggest a figure close to 7/100k whereas everyone else is getting much worse.

[xenfacta]

my worst ecenomy to date is 9.5 and i have a heavy foot. im usually about mid 8's with mostly city driving. around 500-550km a tank is normal

[andyhui01]

^manual or auto?

[xenfacta]

manual 1.8

[andyhui01]

hmm... if you can see my spreadsheet, I get about 100km's less than you on everytank (with I guess 50/50 driving), very light on the pedal.... what petrol do you use?

[dmx]

you're very good bookkeeper !!! :thumbsup::thumbsup::thumbsup:

[xenfacta]

jus normal ULP, usually from shell... my trips are city but theyre also longer.. the car is getting a chance to get to operating temp... ive been on study leave this week and its been shit coz i havent been going more than 5k's or so to anywhere, just to the gym n that on my breaks...

i reckon if ur car is tuned for standard petrol, using premium wont make a difference....

[andyhui01]

^hmm.. I use Unleaded 95, after a few tanks of BP, if I don't see improvements, I will go back down to regular ULP.
My cars economy is pretty shit as I do alot of inner city suburb driving and alot of short distances and a @(I&*$ load of traffic lights, so I guess that isn't helping it.
dmx, it helps if you do Commerce at uni :D

[spanks]

costs me about a dollar a kilometre.

We have a SS Commodore,XR8 Falcon,LS Integra,CBR600RR and non of our machines use this much fuel.
You got serious issues if you are using this much.

[chylld]

my auto sport drinks 12L/100km average... i don't thrash it either. just the usual to and from work.

[amurray]

just used E10 from caltex... got 680km of the tank so far.. still 4 little bars... and i was giving it to it

[Arcturus]

These figures are so confusing, 12l/100km driving conservatively, now 680km from a tank without driving conservatively... it seems the new Civics are much worse.

[denot]

Chylld sports auto has a lot, i mean A LOT, issues.. so this 12L/100km is possibly to happens with his car. Mine got around this figures when my uncle driving it for a week (and trash it a lot T-T).

Any1 try the new 10% ethanol ULP from Caltex on our new civics yet? Pro cons using this?

its the short distances that kill it on any car... the car needs time to warm up for the best economy... also the start stop isnt good for it.. taking off takes a lot more fuel than maintaining speed.. thats why highway driving is so good for fuel economy....

ppl get spoiled on driving 1.5, 1.6l engines, naturally they use less. im stoked with mine (well i jumped out of a supercharged v6 lol, 14-16l/100km). my old mans gti is a 2.0l and that does around 10l/100 in city/suburban traffic

can someone elaborate further on the 10% ULP? It seems like the EG civic got a good economy, but thats 1.6 so its a diff story, and with the new civics, it seems like the new civic has a huge range, I've heard of auto 1.8l's doing 550-600 on a tank and some people can get about 350 a tank.

The FD civic is also much heavier than the EG civic.

[andyhui01]

btw, just curious, to those guys who get 500-550 on a tank, do you guys pull out the nozzle after it stops or do you pump extra litres in? Because I should point out, I pull out once the nozzle stops (round to the nearest 10c so not much diff) and about 50&#37; of the time when I start my car, I am 1 bar short of full (and even if its full, it'll go away in less than 5km)... do you guys experience this or does everyone just pump in an extra 2l or however much?

[denot]

i agree with u andyhui01... usually i put some extra in, but last time i pull of when it stops (cos its exactly on $30) then it was 1 bar empty... strange strange

[amurray]

ok i used E10 from caltex.. tank is now empty.. 760km out the tank... wich is manual vti witch is r18a, anyone gettin less then 450 must be flogging the nuts off the darn thing... or using crap fuel...

[xenfacta]

what kind of driving u doing

[andyhui01]

^how can there be such a big difference? I've tried driving 100&#37; to get the best fuel consumption, very very light on the accelerator, rpm never went about 3k rpm. I've already tried Shell 95 and BP 95, very minimal diff, the BP is just slightly better. If there are more people on his side, I might have to try switching again.

[amurray]

umm did a trip to byron bay and back... still had more then half a tank... rest was comb of city and highway... hit rev cut quite a few times... 1st 2nd and 3rd

[IAMVTEC]

I get 450k at best from a full tank, usually about 400. I spend about $40 a week on fuel. Automatic 1.8

But I love near city, so I always in stop start traffic.

[IAMVTEC]

I think because

1.they drive a manual=more fuel efficient
2.More highway driving
3.less usage of vtec

thats maybe my explanation for why some people get better fuel economy. But I agree with you, my auto gets pretty bad economy no matter what I do!! I'll be happy with just 10L/100km.

[andyhui01]

^ I know manual would save abit more fuel, but not that much... and I'm pretty sure I did not VTEC it when I tried to get the most out of my tank, I like right in the CBD, as in postcode 3000 so I go through alot of stop start traffic, I would guess its about 50/50 for highway and city for me.

Even the other Manual 1.8 civic could only do 500-550, not 600+

[amurray]

maybe they changed something for the 2007 model lol... cause was quicker on 1/4 then a sports :S... and using less fuel lol

[ido09s]

First post here for some time and am now going to be an 8th Gen Civic owner so will be back here more often :)

Seems some very very different results on fuel usage from everyome here. I am having mixed feelings on buying the new Civic however am hopeful i will be one of the lucky ones that gets great fuel economy :) Getting out of an Echo that is able to get 550-600klms out of 36 litres i am hoping to get around the 8 litres per 100 from the Civic, fingers crossed....

Will give my findings on fuel economy once i have driven the car for a tank or 2 :P

[gr1d]

Mine is about 10L/100km, vti auto 1.8. Mostly short trips, around 25km a day. I used normal unleaded bp/shell/mobil. I've just started using Shell V-power, anyone here using v-power? any pro and cons? IMO, the car feel smoother, but looks like drinking the same amount of fuel...

[Arcturus]

Ok i've just run through my first tank, which got around 380 km on 34.5 litres of whatever kind of petrol the dealership put in. That works out to be around 8.5l/100km, can I expect a significant increase on the next few tanks?

It's a VTI-L manual.

[xenfacta]

what kind of trips were u doing? that sounds about right

[Arcturus]

I drove mostly through suburban streets with little traffic. After about 200km I travelled further out of Melbourne where there were less traffic lights but more turns and varied speeds. Overall, generally outer-suburban driving.

[UNLS1]

my auto sport drinks 12L/100km average... i don't thrash it either. just the usual to and from work.

geez my 5.7lt V8 calais used bout 13-15 just round town!

my mrs just got her civic sport autop yesterday, ill see wat shes gettin on that

her brother gets his Civic type R on thurs, ill look at his, when i was drivin mine i was gettin like 9.5lt/100k round town and 12/100k when i was in 8,000 land!

[16CTEG]

best way go to the gym and shed a few pounds helps with economy and your mrs might appreciate it too! Win Win situation!!!

[gerard]

Ive been getting consistant 9.5l/100km since new and even after filling with 5w30 synthetic oil.
took a trip to geelong and back and only achieved 9.2, expected better.

Have fitted Denso Iridiums yesterday and will report if theres any improvement. Car feels smoother and quieter somehow with the Densos

[EuroDude]

New Car = high fuel usage. Because the engine is still wearing in.

Expect the fuel economy to be on par at around 15,000km


My Euro was eating 16L/100km but now its down to 9.xL

[TypeRice]

driving habits can increase your consumption up to 40%.

it is one of the best cars for fuel economy, but you need to learn how to drive economically.

with my integra, I can get 350 for a tank or 500, depending on how i drive.

civics have 45L tank..
and when the fuel light comes on i go refill..
and it gets full at 37L (whilst refilling)
hence you still have 8L in your tank when the fuel light turns on.
and 8L can take u about 100kms extra.

just wondering is your 500kms based on when the fuel light turns on? or using that 8L to push the petrol to the limit ?

[yourfather]

should I get one of these cars?

[clem]

ok i used E10 from caltex.. tank is now empty.. 760km out the tank... wich is manual vti witch is r18a, anyone gettin less then 450 must be flogging the nuts off the darn thing... or using crap fuel...

Not calling you a liar, but may I ask how much fuel you used in doing that 760? Because even if you did use all 50L of your fuel which would cause your car to break down on the side of the road..

calculating your L/100km's

.. 760 / 50 = 0.658 per 1k
0.658 x 100 = 6.58 L / 100km's

So since its impossible to use up all 50L's, lets say you drove with 5L's left in your car..

760 / 45 = 0.59
5.9L/100km's

That is a whole liter below honda's rated 6.9L/100 which people rarely get even if they drove like granny's.

With most drivers here claiming 7-8L's / 100. I cannot see how it's possible your car was able to get 760L's. just like to know what's behind this thats all.

Based on your claim, my assumptions would be:

Caltex E10 is magical fuel

Theres a flaw with how you calculate the fuel usage of your car (maybe you just forgot to reset the odo from the previous tank so the KM's added on.)

[yourfather]

maybe he has a hybrid

[buddah51au]

To everyone complaining about fuel ecconomy from the 8th generation Civic. I purchased a VTI auto in July, 2006 and have kept a comprehensive log book on the vehicle since that time. To date i have travelled 22,000kms at an average of 7.06 ltr/100km. Best recorded is 6.51L/100km, worst 7.5L/100km. I have only ever used standard unleaded fuel from my local woolworths petrol station. As this vehicle is advertised at 7.2L/100km i am fractionally in front of that. To me it is a great car that has given no problems to date.

Clem, add this to your unbelievable list. 667km on 44.5 lts. the first 280 km on that tank around town, so a figure in the mid to high 5L/100km is what i would expect on a long trip....on standard unleaded fuel

How you guys get that log? Manually calculation? Or does Civic have built in fuel log program?

[denot]

How you guys get that log? Manually calculation? Or does Civic have built in fuel log program?

hahahaha... built in log program will be cool... :p

[buddah51au]

Every one using this forum obviously has a computer, so if you go into microsoft word it is quite simple to make your own log book. It takes all of about 5 minutes every week to keep it up to date & with a calculator it is very easy to keep an eye on fuel consumption.
The other reason for the log book is being a qualified mechanic i prefer doing all my own servicing, well i probably over service the vehicle in the hope of a pro-longed life.
After that it is up to each individual to understand what they are doing in the way they drive their vehicles in relation to ecconomy. It is not a matter of treating a car like a baby, just drive it smart.

[oniononline]

There is a fuel used / km traveled program on certain cars, the new Subaru has it and I've even read something like that can be unlocked in Mazda 3 cars, just wonder if there is one figured out by someone haha.

[denot]

It is not a matter of treating a car like a baby, just drive it smart.

Haahahaha... for me, I treat my car like a baby by driving it smartly... ^_^

anyhow, my fuel consumption was rather absurb today... just fill the tank 32.85L for 311.15kms... -_-" (too much heater???)

[clem]

hit rev cut quite a few times... 1st 2nd and 3rd

Just trying to say that its highly unlikely that someone who hits rev cut at 1st 2nd and 3rd 'quite a few times' is able to achieve 760kms in the same tank.

Clem, i agree wholeheartedly, 760km per tank under exteem driving conditions could not be achieved, except in dreams

[buddah51au]

Haahahaha... for me, I treat my car like a baby by driving it smartly... ^_^

anyhow, my fuel consumption was rather absurb today... just fill the tank 32.85L for 311.15kms... -_-" (too much heater???)

hmmmmm...10.56L/100km compared to my worst ever of 7.6.

[xenfacta]

hmmmmm...10.56L/100km compared to my worst ever of 7.6.

whats ur daily commute like?

[amuson]

i do pretty much normal driving with some highway driving and get 500km or so out of a full tank out of my fd2 manual

[buddah51au]

whats ur daily commute like?

My daily comute is a 90km round trip, 60% rural back roads & 40% town.

[denot]

hmmmmm...10.56L/100km compared to my worst ever of 7.6.

indeed this was my worst... bear in mind i have the sports, auto, 80% city (slow-stop) driving and heater always on whenever i drive with my fiance... usually i only do around 8.5-9L/100 kms...

[xenfacta]

My daily comute is a 90km round trip, 60% rural back roads & 40% town.

that makes sense then.. mines like 40km in the city/ inner suburbs lol

[buddah51au]

As an update on my last 5 tanks fuel consumption has varied between 6.51 & 6.87 L/100k. engine must be starting to loosen up a little.

[gerard]

nows winter, noticed my fuel consumtion has gone up to 10.5/100

[buddah51au]

Would you mind telling me please how being winter effects fuel consumption? It is winter here as well & for the last 6 weeks (500 to 600km per week) i have used less than 7L/100km. Only fractionally but very consistant.

[denot]

heater on all the time? QLD doesnt have as "wintery" as NSW or MELB... so I dunno if you need heater on in QLD...

[^^v]

i woulda thought u'd consume more in summer... as the a/c is constantly running...
i think the heater would have minimal effect on fuel consumption...

[denot]

Not too sure about that... but what I thought is that in summer, you just have the A/C on mid (24-25 degree) and set the fan to high to save fuel... but for heater, no matter how many degree you set, it will consume the same fuel as if you put them on max (or Hi in our civic)... any tech ppl can help?

[buddah51au]

Using a heater has absolutely no effect on fuel consumption....period.
Think of a heater a a very small radiator situated behind the dash with a fan attatched. You control both the amount of hot water flowing through the heater radiator and the fan speed.
To the person who said it does not get cold in QLD, 14 consecutive mornings below 0 deg puts a quick ebd to a crazy comment.

[denot]

Well thats only for this year I believe... the coldest ever for the past 20 year (according to chnl nine)

[buddah51au]

I stand bye my original comment, cold weather & using a heater has absoultely nothing to do with fuel ecconnomy.
You made the statement it doesnt get cold here, well let me tell you it does, every year we have cold weather, & that is coming from someone who lived in the southern highlands south of sydney.

[denot]

anyway... lets not continue the "weather" topic now shall we? :angel:

Just refil my car again today 31.50L for 321kms...

[Stubbsalicious]

Just bought my Civic VTi-L Manual about 4 weeks ago. I always fill up after 500k's, which is exactly a weeks driving for me. That uses just over 34l. So normally running at just above 6.8l/100km. That is about 40% highway and 60% in the streets.

[ido09s]

summer will of course affect fuel consumption as the air gets hotter and we all know how much engines love cold air. It may not be as noticable on a naturally aspirated car such as the Civic, but think of how much better a turbo car goes after having an intercooler fitted, and that is forgetting about the AC being used

I so far have gotten good fuel consumption.

first tank, a bit of highway driving 562klms, 45.2ltrs 91 octane
second tank all round town, 593klms, 43ltrs Mobil 91 octane
third tank all round town, 562klms, 45 ltrs and a bit of thrashing to help finish off the run in on the engine.

I have just filled up with BP Ultimate so will see if the 98 makes fuel consumption any better

[buddah51au]

I have noticed very little difference in fuel consumption, winter or summer, using air con or not. my all up average fuel consumption over 23,000km using standard unleaded fuel from woolworths is 7.05Lts/100km. Hard to beat i think

[andyhui01]

I've been averaging low to high 8l/100km and on a recent trip to Mt. Buller, did 8l/100km even with all that overtaking and a couple of redline's on the B-roads... but I'm still not getting 500k's on a tank... nowhere close when I'm in the city, only do about 400-420km's and I'll refuel (2-3 bars left).

[denot]

any1 have the sports so I can compare mine with?

If your fuel guage is as accurate as mine, with 3 bars left you still have at least 100 km to go. I recently travelled 30km with no bars showing, yet it took 43 lts to fill it to the brim. bear in mind it is a 50 liter tank.

[denot]

If your fuel guage is as accurate as mine, with 3 bars left you still have at least 100 km to go.

Finally we agreeing on sumthing here buddah :p my mate Vti was running around 100kms with 3 bars left and the car finnaly stop just when he about to enter the petrol station :p

[buddah51au]

Finally we agreeing on sumthing here buddah :p my mate Vti was running around 100kms with 3 bars left and the car finnaly stop just when he about to enter the petrol station :p

so his gauge reads differently to mine, but that is not uncommon. wether u agree with me or not is your decision, but after 38 yrs as a mechanic owning & working on hondas since 1989, i think i know a little bit

[ido09s]

I have done about 50klms with no lights opn the gauge and still had about 5 litres left in the tank which is great

[buddah51au]

I would like to share with everyone my fuel consumption figures for the last 9 weeks. All of this on standard unleaded fuel from my local woolworths station. I dont believe i nurse the car, mostly the cruise control is set 3 or 4 kph above whatever the limit is. Once a week the car is redlined in 1st & 2nd to give it a good run.

Distance travelled liters used consumption

640km 44.5 lts 6.67 L/100km

[buddah51au]

try again with the next 8 weeks

549km....37.04 lts......6.75 L/100km
553km....37.62 lts......6.80 L/100km
517km....35.62 lts......6.89 L/100km
496km....34.28 lts......6.51 L/100km
485km....33.33 lts......6.87 L/100km
524km....36.59 lts......6.98 L/100km
444km....29.62 lts......6.67 L/100km
439km....29.30 lts......6.67 L/100km

Remarkable figures i think and very consistent.

[denot]

hey buddah... I need your help for this... will turning cruise control on more often consume more fuel? How about Paddle Shift?

just fill in my 06 Auto Sports again yesterday, driving without ever pass the 3,000 rpm last week using padle shift (and randomly mix with auto driving + cruise control on highway).

Consume 35.12L for 332kms... :confused:

[buddah51au]

snd me a private message with your email address. I believe there are definately a few tricks involved in achieving the figures i do and it definately requires a certain driving style. I also found the only way to achieve accurate figures is....as much as possible fill your tank using the same pump bouser each time so the angle of the car doesn't vary....the angle of the car when u fill it can make a difference of 2 or 3 liters, and on a small tank this omount of discrepancy makes a lot of difference to the figures achieved.
On a side note, i am looking forward to doing a trip to sydney 1 day, 1500km of which 1/2 of that distance will be flat open country......i will be disappointed if i dont average under 6L/100k....everything points in that diection in my opinion.
example.....previous car....EF Fairmont....weekly commute ave 10.8L/100....dropping to an average of 9.1 on a trip to sydney

[denot]

thanks buddah... you've got pm! ^_^

[buddah51au]

For the last 10 weeks i have been experimenting with filling at the same bouser each time, so that the car is in the exact same position each time it is filled up. I am now certain this is absolutely vital to get accurate readings (plus or minus 1 liter makes a big difference in gauging fuel ecconomy, especially with a small fuel tank). The end result of this is that the weekly results have been very consistant ( a best of 6.51 l/100 & a worst of 6.98
l/100, average over 10 weeks = 5,044km - 343.08 lts = 6.8 l/100km).

My next experiment, if i can ever get the courage to do it, is to let the wife use the car for a week to see how much difference there would be between different driving styles on the same roads.......that could be an interesting result. If it ever happens i will post the result, but for now i think i have posted enough on this subject.

[denot]

my updates: yesterday fill - 36L for 366kms

[buddah51au]

compare that to my fill up today - 360km - 25.18 lts. I realise the Civic Sport cant be compared to the VTI as they use different engines..... but an additional 11 lts to travel 6 km further.......Sport is used in city driving compared to vti used on rural back roads would definately account for a percentage of the difference. other than that i would have to get ho;d of a sport for a few days & use it under the same conditions to do an accurate comparrison.

[denot]

Oh and I fill it with different ULP as well, using Shell instead of Caltex this time (will it matters?)

[buddah51au]

i am now up to 11 consecutive weeks of registering under 7L/100km, so i got the calculator out today and came up with the following figures. This is my overall fuel consumption since i got the car....these figures have been double & tripple checked.......24,268kms, total fuel used = 1703.49 lts. to me a remarkable set of figures

How do you check the litre consumed? I think I have to start to check as well since the drop in the console was really drastic lately.

[denot]

filled on monday (and this time I only use my car for 10-20kms a day and the rest kms are on weekends) 26.65L for 251.52kms... T-T

Well, if you reset your trip counter when you put fuel in, then you know at your next refuel how much distance you have travelled for the amount of fuel you have to top up again.

[andyhui01]

buddah... the figures are pretty impressive, I am nowhere near your fuel consumption with a VTI-L Auto.

http://www.phyrefile.com/pic/2007/08/22/untitled.JPG

but I live pretty much 1 suburb away from the CBD which means I prob go through >10 traffic lights about 50m away from each other every day...

[denot]

andyhui, i think my figures are close to yours as well... T-T

[buddah51au]

andyhui01...... I am very impressed with the figures and i honestly thing you would be hard pressed to get better without going to a very small car. nothing that compares to a civic can get close to it on fuel consumption. I also believe the programing of the auto trans is a big help. we are planing a trip to sydney later this year and i will be very surprised if i dont average under 6l/100

[andyhui01]

denot... bear in mind that I'm in the (VTi-L) 1.8 engine and you have the (Sport) 2.0 engine... I am by no means saying my fuel consumption is high but I remember reading on one of the fuel economy discussion threads (and also the singapore civic forum) that there are people doing 600k on 1 tank, and people who have a constant 8l/100km fuel consumption...

buddah, I don't understand, how are you impressed with my figures when you do <7l/100km on practically rhe same car (the weight difference on the VTi-L and Vti is very minimal I believe)

[buddah51au]

i am impressed with the overall figures i get....not yours....every car is used in deifferent conditions.....fuel consumption reflects those conditions as well as they different driving styles people have

[andyhui01]

^yea... I agree, just curious... could you give me a percentage of highway/city driving?

[aaronng]

Since he uses cruise control most of the time, I think he does highway. When I did highway, the Euro's 2.4L returned 7.2L/100km, inclusive of a few runs to redline.

[buddah51au]

no highway work...mostly rural back roads with 35&#37; town

[buddah51au]

as for cruise control........ i only use that on flat roads

[buddah51au]

So that people such as aaronng get their facts straight i did some measurements today. each weekday i do 4 trips of 22.4km, of this 10.3km is in a 100kph area, 7.8km in a 80kph area, and 4.3kn in a 60kph area. cruise control is used for 9.5km each trip (traffic permitting)

[andyhui01]

and because you are in the country, I assume that there are almost zero traffic lights? or maybe 1... so the journey is non-stop with no stop start traffic as well?

[buddah51au]

LMFAO......people & there assumptions.....sorry to say andy that your wrong as well, i think it is 11 or 12 sets of traffic lights.....stop start traffic is variable from day to day, but yes it is not like heavy city driving.

[krogoth]

if its rural, then thats considered highway driving

i get 450kmz from 38L of 98 octane

generally thrashed driving, 80% in a fair bit of traffic, and tons of traffic lights

hey buddah... just curious, can you do me a favor to time your 0-60km/hr from stopping at the trafic light on a, say, 60 km/hr area? I try to follow your suggestion on the email before, and now Im driving 0-60kms in a very very slow time and still the consumption is fairly sitting around 9-11 kms/L.

hope you get what I mean... thanks ^_^

[andyhui01]

^denot... unless you live in the country, you'll never get the same consumption as buddah... when I accelerate to 60, my rpm doesn't go above 2200rpm and my consumption didn't change much.

secondary back roads are a lot different to highway. some time in the next few mths i am planning a trip to sydney & i will then report what highway consumption is. it will definately be under 6l/100k.....but how far under is the question. but a round trip of 4000km will give a very accurate reading.

i have never timed myself, but i will guess around 15 seconds using 3000 to 3500rpm as a change up point

Andy.....if you go back to the beginning of this thread, it began because 8th generation civic owners felt that Honda were advertising fuel consumption figuers that were unrealistic and impossible to obtain in real world driving. I think the manual is advertised @ 6.9L/100 & the Auto is 7.2L/100. The majority of people living in cities have no chance of getting close to these advertised figures because of the conditions the vehicles are operated in. People seem to forget that the advertised figuers are averaged out. If people dig deep enough on overseas web sites they will find where different consumption figures are advertised for the same car....eg in England the civic is advertised @ 5.4 L/100 country & 8.9L/100 city. I do not know the criterea used to obtain those figures. Iether way, the civic is by far the most economical car in its class available in this country & given the RIGHT CONDITIONS the advertised ecconomy figuers are obtainable.

[buddah51au]

I am off to Sydney shortly, so i will be able to inform everyone how far the current model civic 1.8 ltr Auto can go on 1 tank of fuel as well as the best, worst and everage fuel consumption. As the round trip will be between 3,500 and 4,000 km i will be able to gauge very accurate figures and to be honest i will be disappointed it the average is over 6L/100km

[buddah51au]

I personally think the fuel consumption issue is caused by the way the consumption figures are advertised. While it is possible to achieve the advertised figures it is impossible when driving in the city. If you look at the Honda United Kingdom site you will see they advertise seperate figures for city and highway. Here are there advertised figures for the 1.8 ltr engine.......
Manual......City = 8.2L / 100km.......highway = 5.4L / 100km........................
Auto.........City = 9.0L / 100km.......highway = 5.4L / 100km........................
Type R......City = 12.7L / 100km......highway = 7.0L /100km.........................
From reading this site the city figures seem much closer to what most people are achieving, as for highway figures i will know soon

[Borg]

I do mainly city driving, although a lot of it is @ 80 to 100kmh on freeways around Melbourne.

I found my Integra got between 7.8 and 8.2 L/100km. Honda quoted 8.0 for city driving and 5.2 for highway driving.

It will be interesting to see what sort of fuel economy I get with my Civic.
So far I have done almost 400kms on the first full tank with fuel gauge still showing 6 bars. Seems pretty good.

that sounds about right.. thats what i get at the moment in my vti and i dont really drive for economy.. im ecstatic with it. (i swapped from a car that was doing around 17-18l/100km).

[denot]

went to the Central Coast last Friday... 17.2L for 190.6kms!!! YAY!!!

btw, any1 kno is the Caltex's E10 unleaded is good or bad?

Yeah, good question denot, I stopped at a Caltex the other day and thought "Hmm, it can take E10 can't it.." but opted for normal unleaded anyway.

I've always run on the normal stuff since I picked up the keys, 33,000km ago - would switching to E10 now do anything funny to the engine? (he says as he desperately tries to remember what he learnt in engine design all those years ago at Uni :o )

[buddah51au]

[denot]

I would not use E10 unless it was a last resort

hey buddah, Can you explain a bit why?

[clem]

I was under the impression that E10 was safe to use if you fill up regularly (drive often) and don't leave the fuel in there for long.

[buddah51au]

I have just completed a return trip to sydney, a total distance of 3,084km in 7 days. Overall the fuel consumption was very impreesive and my findings tell me the VTEC system works exactly as it is described (to my understanding of it). The bottom line is fuel consumption is very much controlled by the speed drive at. My understanding of the IVTEC system on the R18A engine is that it is most efficient in the 90 to 110 KPH range & i found this to be completely accurate. My findings were this.....eg; with the majority of cruising @ 108KPH on cruise control i returned a figure of 6.28L/100km, however if you increase that to 118 KPH, again on cruise control for extended periods the average fuel consumption increases to 6.55L/100KM. But the real eye opener for me was having the wife drive for a period of time (on P plates), therefore the Cruise control set @ 101KPH, followed by 400kms of night driving on Kangaroo infested roads where i had the cruise control set @ 90kph (I did not want to put a roo through the radiator so if u want to call it grandpa driving i will accept that) I got my best consumption figures for the trip......577km / 33.45L
and that equates to 5.8L/100km. One other thing i would like to mention is that from Maitland to Campbelltown, 2 days of city driving and back to Maitland i averaged 7.19L/100km, exactly as advertised for the VTI. Overall figures for the trip....3,084km / 199.79L = 6.48L/100km...............................
Please note that these figures could never be expected in the Civic sport with the 2.0 liter engine.

[buddah51au]

hey buddah, Can you explain a bit why?

I will answer this question in the next few days after i do my research again

[markCivicVti]

Well done buddah!! Fantastic logging! The fact that the auto isn't a 4 gear auto-box must make a big difference with the fuel economy at those higher speeds.

[buddah51au]

Well done buddah!! Fantastic logging! The fact that the auto isn't a 4 gear auto-box must make a big difference with the fuel economy at those higher speeds.

Thankyou Mark. In MY OPINION, The 5 speed auto is a major reason in choosing the civic over other vehicles in the same class (before considering build quality, reliability & resale value). The gearing of the transmission helps not only in fuel consumption, but it also leaves me with the opinion that here is a great small car that can comfortably cruise long distances without overworking any of the running gear as all Highway cruising is done between 2000 & 2500 rpm ( yesterday we covered 1396km in 16 1/4 hours...minus 1 1/4 hours for stops....so 15 hours driving time). I will say that i have never been a fan of Auto gearboxes in 4 cylinder vehicles, but here is a great example where they work well together. In saying that, i believe i caught the electronics out on 1 occasion ( for those of you that know the New England Hwy, there is a long downhill run from Willow Tree to Murrurundi. Here the gearbox was continually changing between 3rd & 4th, unsure what gear to hold, and then on flatter sections it would not change into 5th gear. At 1 point i actually thought i had lost top gear all together). I would actually prefer a manual control so that i can dictate the gear i wish to be in, maybe that change will be available in future models. 1 thing i did enjoy was the long uphill climbs on the F3 freeway where it would change back to 3rd gear and hold 5000RPM all the way to the top. Like all honda engines the R18A loves to rev when given the opportunity. The Bottom line is that i would recommend this car with an Auto transmission to anyone, even above the manual gearbox.
Sitting in a traffic jam for 2 hours on Pennant Hills Rd Due to a Bus accident or attempted Hijack - whatever it was .....definately not fun....and worse in a manual.

[aswanderers]

hey just to share what my FD2 can achieve 538km for 32liter of petrol... did it once .. drive normally just didn't rev above 3.4rpm 40% city 60% highway driving...

but since this records I nv drive such a mileage again, cos I am not playful driver... so on average my mileage is 410 to 440km for 42 liter.... 10km/L

[buddah51au]

hey buddah, Can you explain a bit why?

Sorry for the delay in responding Denot and i stress that it is my opinion only not to use E10 fuel when i can buy standard 91RON. Individuals must do their own research and form their own opinion.

I suggest anyone contemplating using E10 fuel should first do a web search on ....... "E10 fuel problems".....and read several of the articles listed there.

My other concern is that i personally do not trust fuel companies, we have all heard on accasions about sub standard fuel being distributed. How can we, as concerned consumers be absolutely certain that fuel companies on occasions will not stretch the legal requierments and up the ratio to more than 10% ethenol.....we cant. 91RON fuel has a proven track record over many years, at theis point in time E10 has no track record and there are too many various opinions on wether it is 100% safe and compatable or not. So this little black boy will stick with a known product for as long as possible.

On a side note i have noticed that E10 fuel sells for 2 cents a litre less than 91RON, yet the common belief is fuel consumption will increase between 1 and 3% when using E10. So in actual the cost saving is lost in running costs.

buddah tahnks for this... by only ready the last paragraph is already enough for me to not to try it... I fill my tank twice (on the trip to Central coast and return) and the consumption is CRAP! 30.8L/274.3kms (11.2L/100kms) and before its 30.78L/268.8kms (11.45L/100kms). Remind you that this is mainly Hwy driving... if using normal unleaded for hwy driving: 17.2L/190.6kms (9L/100kms).

From reading this thread over the last few weeks, its quite obvious that not all civic are 'identical'. i personlaly myself do not see the appox 7ltr/100km as advertised. Its more like 10ltr around town.

Also, my car pings when running 91RON, which I believe has something to do with fuel economy.

AND YES, the owners manual states that 91RON is acceptable so no remarks about being tight and not using 95ROM or higher please, which I do occasionally. Dealer has looked at it 3 times for this issue now. The last time they took snapshots of the ECU when the engine started to ping at different rev's under driving conditions on the road. Just got a reply back today that the ECU timing is normally between 12-18 deg, and the knock sensor is picking up the pining and the data shows its retarting the timing to -12 deg when it happens. Is this right????? The knock sensor is meant to prevent detonation correct? Why is it that I still hear the sound of 'tin cans rattling' still then? To me, the engine is still pinging, regardless of what the knock sensor is doing.... Anyway, their answer is 'oh it must be the fuel quality'. Like I haven't tried a dozen different stations and get the same result. I told the dealer I was going to escalate the issue with Honda Australia....

So with the R18a implmentation of i-vtec, is it possible stay in the fuel efficient cam when gently accelerating up from a stand still? Or is that load too high, and hence the R18A will stay in the normal 'hot' cam mode?

According to the diagram off TOV on the R18A implementation of i-vtec it seems like provided you are accelerating below 3.5k rpm it will stay on the efficient cam. I suppose my question is.. would slowly accelerating in the lowerer gears (staying under 3.5k rpm) be classified as a high enough load to stay in the hot cam?

My understanding of the IVTEC system on the R18a is that the change over point from ecconomy cam to normal cam is 3200RPM. The IVTEC apparently only works under light throttle and light load situations, and the load is determined by the computer. SO yes, light acceleration is the best way to stay on the hot cams and leave the rest up to the computer.

[buddah51au]

For those who are interested i have just clocked up 30,000km, so spent some time calculating average fuel consumption. The figures are as follows.............
29,815km - 2,069.75 liters - average = 6.942 L/100km

[denot]

I've got my best fuel consumption ever on my Auto Civic Sports!!! Went to Hunter Valley on the long weekend (75&#37; F3 drive, 15% Country drive - very min traffic, and 10% traffic+city drive) and here is my consumption:
33.68L for 457.4kms which means 7.36L/100kms!!!! A lot better than what I use on my last 6 city driving (avg 10.77L/100kms)

YAY!

[buddah51au]

congrats denot, now u know what is possible

[Joele]

I wonder how this compares to similar priced 2L cars like teh focus and Mazda3?

[buddah51au]

This is 1 area where the Mazda 3 and Ford Focus cant match the Civic. On average they use 1 to 1.5 Lts per 100km more than the Civic.

Due to the engine size differece I imagine..

I would have thought they would also be hit on the auto transimission being 4 speed autos..

Would be great to see an independant comparison of the whole small-mid size range. auto and manual. As we know we can't trust the manufacturer claims, esp when they make different claims for the same car in diferent regions.

Before i brought my Civic i was looking at 3 cars, obviously the Civic, as well as the Mazda 3 & the Focus. I distinctly remember the Focus was favoured due to the 1 i wanted being in stock, and from memory they were offering about $2500 more for my trade-in. As i knew the dealer i was able to have a demo for 1 week and apart from the handling of that car i was not impressed. Add to that the Focus is built in Sth Africa, build quality was suspect along with poor resale values. I averaged 8.2L/100km for the week doing about 600km. Also i was not keen on the fact that @ 100KPH the engine was spinning over @ about 2700RPM from memory. that = more wear & tear & effects fuel consumption.
As for the Mazda 3, a nice car, similar RPM @ 100KPH, average fuel consumption over 1 week = 8.4L/100km, but i also disliked the amount of road noise entering the cabin on secondary rural roads.
As for the Honda, the handling does not compare with the other 2 cars as it is tuned more for comfort ( a bonus when u have serious back problems). I was immediately impressed with the 5 speed auto allowing the engine to spin over @ about 1800RPM @ 100kph, Fuel consumption for the week was 7.3L/100 KM.
Add to that Honda build quality and reliability as well as better resale value, the feeling of a much roomier interior and i felt in the end there was 1 clear winner amd even though i had to wait 3 months for the Civic & got considerably less trade in than the Focus but more than the mazda. Now after 15 months i am still very impressed with the car and obviously the fuel consumption is outstanding.
Being an X mechanic it takes a lot to impress me, but the Civic has done that and continues to do so. i would recommend this car to anyone.

[buddah51au]

I will add to the above and say that in my opinion there are 2 major problems with the Civic. 1 is the blind spot created by the "A" Pilars ( a definate safety issue & 2, Poor quality headlights for rural driving. This problem i have overcome with good quality driving lights, But the blind spot issue you have to live with.

[Joele]

As for the Mazda 3, a nice car, ... but i also disliked the amount of road noise entering the cabin on secondary rural roads.

OT: Same problem in the older 323 I am trdaing in on the Civic..

[Borg]

When I decided to buy a new sedan I did a lot of research into a range of cars. I eliminated the Focus and a few others early on in my research for various reasons, such as price, built quality, and various other issues.

In the end I favoured the Civic VTi-L over the Mazda 3 Maxx Sports and new Toyota Corolla Conquest because of the 5 speed auto and better fuel economy, but it wasn't an easy choice. I was very impressed with the Mazda, and got to do a lot of test driving in it as I have a relo with one.

If I could have afforded an SP23 with the 5 speed auto, it would have made it an even more difficult decision. Then my choice would have been Civic Sport v Mazda 3 SP23. Then it would come down to grey leather v black cloth trim, as the fuel economy of these 2 is quite similar in the real world.

I am happy with the Civic, but there are a few thinks I would change. The A pillars are a problem, but it does enhance the shape and I assume the aerodynamics. I bit more low down torque would be useful, as would a sequential shift automatic transmission. I'm not sure if that would match up well with the 1.8L engine though, as most cars that have sequential shift autos have 2L engines at least.

[buddah51au]

you dont necessarily need sequential shift to use an auto trams manually, justmove the lever through gears as requiered. However donig this on the civic it is not possible to access 4th gear. I will say that i do use the gearbox in this manner when needed.

[markCivicVti]

Yeah I fully use the lever to control what gear I am in with my auto box.

I get told I drive my auto like a manual - in the sense of I decide at what revs I'll let the tranny go up a gear. Of course I don't always do this... but once in a while.

I haven't received my civic yet, but could someone let me know what slots you have on the fd1 with auto (i.e is it 1,2,3,D,R,P?). Also is there a hold button? My festiva with auto box has a hold button that seems to force the tranny to use a gear lower than it normally would use - or maybe that it wont shift up when revs go higher. For example on 2, after I push the hold button the revs jump up... and it feels like it must have gone to a lower gear.

I already drive it like that quite often as I have a few hills to negotiate in my area. The problem is that the transmission likes to jump to 5th once you shift from D3 to D, and often "hunts" between 4th and 5th going up or downhill at speeds around the 80-100 kph range. I usually just leave it in 3rd going uphill, but when I am going downhill I would like to be able to hold it in 4th.

agree!!! almost kill 2 pedestrian on a pedestrian crossing caused by this :(

[buddah51au]

I have spent the last few days coppying my log book to a spread sheet which i will be updating on a weekly basis. If anyone would like a copy so they can do the same just let me know. Maybe you can do something similar so that you always have an accurate fuel log and not a weekly guesstimate.

[denot]

me doing that too now buddah! ^_^ on my mobile but...

[marc-o-lishuz]

Sorry to chime in so late, but here are the specs on my Civic Si -

Tank capacity - 50L
Average KMS - 360km per tank
Price of fuel - $1.50/L (Premium 94 Octane)
Driving habits - aggressive
City/Hwy - 100&#37; / 0%
Engine mods - None (pure stock intake, exhaust)

You guys don't feel so bad now, huh? If I wanted economy, I would have opted for the Hybrid... but 197hp is way more fun! :p

Is there no Hold button either? I find that strange... that a festiva auto box would have it yet a nice new 5 speed auto box for a civic doesn't.

hmmmm never heard of this "hold" in any other car as well...

[markCivicVti]

hmmmm never heard of this "hold" in any other car as well...

I've seen it on one other - but it was called "Power" instead of hold... and its was on the lever of the auto as well... it may have been my dads 05 SS commodore. And yes a little light comes on the dash indicating its on.

Either way I really like it, gives me alot more control over the gears. Should have gotten my manual license when I first did it. Oh well.

Lol... maybe thats why its a trioS - I never worked out the differeance between a festiva trio and festiva trioS.

fords and holdens, as well as some other vehicles had a so called power button, all it done was change the shift points in the transmission. You did not gain any power from this so called power button.

[denot]

ah I remember now I've seen the "power" button on my uncle's ford...

[markCivicVti]

I don't use it to gain power...I use to to force me down a gear so my revs are higher, be it for engine breaking (lol...ironic.. braking?) or general hooning in the festiva lol.

I use it daily when going down a hill where I have to stop at the bottom of etc.

Either way I find it nifty - use it or not, thats your choice, but having the choice is nice as opposed to not having it at all.
