FD civic average fuel usage / tank

[.k.]

Hey everyone, saw in the manual as i was looking at how to change my rear licence bulbs to led ones and long story short there is a section about it being possible to show the average L/100k fuel usage per tank.

Now in order to do this, you are supposed to press and release the 'SEL/RESET' button repeatedly but i couldn't get it to work. Am i missing the fine print which says that its only for selected models meaning my vti doesnt have it and only vti-l and sport models show you average fuel usage or what?

And anyone else got any tips/tricks that most people dont know that are useful for fd's?

For example, in the middle the handrest can move forward haha

[aero]

For example, in the middle the handrest can move forward haha

lol, i would be pretty surprised if people didnt know that one. but u never know..

[ekdez]

For example, in the middle the handrest can move forward haha

the sales man should show you this one.

errmmm...
1 thing that took me a while to fine was how to change the time. i didnt look at the manual. and i must have been blind at the time cos the button is pretty obvious.

[black8thgen]

oh REALLLY?! oh wait i read this too LOL. but yeah mines a sport model.. so i was thinking i should have it? no idea howto work it.. i press teh sel/reset button as many times as possible it just goes in circles =D

[jckidz]

from what i know, aus spec fd1 & 2 do not have the avg fuel consumption feature. at least not in the 06-08 models. not sure about the new 09 models. only the hybrid and fn2r have this feature.. maybe someone can clarify..

[mr180sx]

yeah the fn2 can show mileage and how man more k's till no more fuel as well as some other stuff

[black8thgen]

must be the hybrid that the manual is talking about then lol

[.k.]

haha wtf so lame.. doesnt even say 'selected models' only got my hopes up.. ah well lol

[warwick108]

well.. they aint very accurate anyways.. did u know.. that the rear passengers have heaters for there feet?.. ^^.. its under the drive and front passengers seats.. =)

[Wayne]

full tank 98 on 400.. full tank 91 at 350-380.. lol.. is that normal?

[black8thgen]

REALLY? HEATERS? LOL.......... woooooow

far out.. ive never gotten 400 atank... i got close to it on a full tank on 96 last week.. i realised going out on longer drives does improve fuel efficiency.. cos going short drives to school and back is so shit =.=

[Fung]

i get really short ones...cant remember how many

but i make really short trips and air con always on~~~

[warwick108]

i get 10ltr/100km.. use 98ron.. =S

[.k.]

fd1 or 2?

[Jackee]

man you guys are getting some pretty crazy numbers from your tanks. new fd1, im got about 320 and im on my last square of petrol on gauge. Ive been using premium fuel as well...auto 2009 model, done 1.6k kms

[warwick108]

fd1.. i think if your heavy footed... ur better off getting the fd2.. with the k20..because the r18 only saves petrol if your revving under 2500.. and the k20..vtec doesnt kick in until 5000.. =S..thats just my 2 cents

[ekdez]

i filled up yesterday.
645km's with 3 bars left. fd1
i only use 98 mobil synergy

[black8thgen]

ekdez how the fuk did u get such a good figure lol. maybe its the type of driving u do? u got an fd2 yea? wait so on our fd2.. it only starts saving petrol at 5000k revs?

[ekdez]

i dont take it over 3000~3500rpm much. im a cruiser LOL.
and canberra is flat and not as much stop start driving like in syd or melb.

dont get me wrong. i did a whole tank of taking it to like 5000rpm max.. maybe a few red lines
i only made it 300km's from that tank.

[warwick108]

no.. for the k20.. it starts eating ur petrol at 5000revs.. but for the r18.. it starts eating petrol at 2500revs.. so.. if ur heavy footed.. ur normal driving in the r18 would exceed the 2500 revs.. and thats when it eats alot of petrol..

[Wayne]

so mine is normal.. haha.. great to hear that.. =)

[FallenAngel]

i filled up yesterday.
645km's with 3 bars left. fd1
i only use 98 mobil synergy

Very nice.. my dad can reach that although i can't lol.


fd1.. i think if your heavy footed... ur better off getting the fd2.. with the k20..because the r18 only saves petrol if your revving under 2500.. and the k20..vtec doesnt kick in until 5000.. =S..thats just my 2 cents

Quite incorrect as the R18 changes into VTEC mode between 1000-3800rpm, when the conditions are right.

[black8thgen]

is he correct about the k20 thuogh? that it saves petrol under 5000k

[Fung]

hahaha same here~~ coz i like to rev up my auto fd1 when driving (but of coz always under speed limit)

i tend to get really short distances...and i am like WTF?

[black8thgen]

shit im confused about vtec on my fd2 now LOL. been reading up on some posts here and elsewhere and some things contradict =/.. or im just a bit silly haha.. can someone clear up whether or not the vtec on the fd2 engine saves petrol up to 5000K RPM?

[williamwong]

FD1 (R18 engine) vtec range is below 2.7899587766k rpm (it varies lol depending on weight etc , its essentially vtec-e that saves petrol)

FD2 (K20z engine) vtec range is starts at 5k rpm, this vtec is to pull more power thus uses more fuel and causing you to shout vtec yo!!

essentially, FD1 saves petrol during vtec range, while FD2 uses more petrol during vtec.

[JOhnnyFD]

FD1 (R18 engine) vtec range is below 2.7899587766k rpm (it varies lol depending on weight etc , its essentially vtec-e that saves petrol)

2.7899587766k.. wow, tats really down to the dot

[black8thgen]

LOL. ah so.... between 1-5000 RPM on the fd2 it will use minimum petrol?

[williamwong]

lol yeh supposedly. uhm..i get average around 300ks for 25L. i think it depends on how many ppl in the car as well, well my car feel sluggish with 5ppl lol.

[black8thgen]

oh i see. haha cheers for the hepl mate =]

[aero]

filled up last week and tried to see how much i could get out of a full tank. i got to about 450kms before the light went on. as soon as it came on tho, i looked for the nearest petrol station to refuel :p

[.k.]

lol resist the urge! how many L did you put in? even when i try to drive around with no bars i get scared and still hav like 8L left.. is there an aftermarket thing that can measure how much fuel u have left in tank?

[Waternmo]

i get around 450km out of a full tank... with occasionally Vtec yo! haha, i think Greddy made infometer that shows the remaining KM and average fuel consumption, it works for OBDII but im not sure what kind of plug we hav in the FDs...

[.k.]

anyone know what kinda plug we have? would be good to know how much fuel i have left in the tank and not fill up so early every time

[liquid23]

I've heard that running your car on low fuel is bad as there are a lot of "crap" on the bottom of the tank so its bad for the engine. So it is always good to not let the light come on or if it does fill it up straight away.

Anyways for my FD2 I have had an average of 470km. This is to when the last bar goes off. I've been using BP Ultimate from the 1st day i got the car.

[markCivicVti]

anyone know what kinda plug we have? Would be good to know how much fuel i have left in the tank and not fill up so early every time

It's OBDII.

[Waternmo]

oh great! than most of the infometers around will work with our cars!

[markCivicVti]

Scangauge2 is popular... was considering it.... but it doesn't look blingy enough lol...

meh

[eeKayFouR]

so how would one go about starting to look up systems to tell us more info about our fuel systems?

[sirdistik]

For what it's worth, i just want to confirm that the '09 FD2 DOES NOT have the avg kms/L.
Honda lent me their '09 FD2 for the day while mine was getting serviced (then they tried to sell me one. LOL).

anyways, i was just reading through the thread and noticed that it wasn't answered. so there you go!

[curtis265]

Well done. Medal for you..

If you read that temple of VTEC site says that for t he R18 engine, VTEC engaged means that the fuel-efficient cams are engaged, but only under the correct conditions between 1000-3500 rpm

Scangauge and dashhawk are both associated with OBDII molesters. have a look around here

[buddah51au]

You guys must have heavy right feet. I had a 2006 FD1 Auto & kept a spreadsheet on fuel consumption for the period I owned the car. Over a 2 1/2 year period i did 59848km & used 4059.03 liters = an average of 6.78L/100km.

I now have a CU2 Euro auto with an average after 14000km of 7.26L/100km.

[Nathan-Mugen]

wtf r u guys serious, i get like 700k's per tank :S, although i do drive 100k's a week, and its all highway :p

[.k.]

highway uses jack all fuel though

[Nathan-Mugen]

oops, miss type, i drive like 1000 k's a week :p

[UCNDRM]

I was on a cruise last night and filled up before i set off, servo is 1.5km from home and did 225 kms and only dropped 6 bars with some heavy pedalling and freeway driving. Not to mention the 15 min w8 2 get outta the carpark.

There were three people in the car if that makes any difference. :)

[curtis265]

lol my R18 sips about 7.5 - 8.5 L/100km. 7.5 is good, 8.6 is when i decide to floor it occasionally

[black8thgen]

fk u all.. my fd2 auto does like 13L/100km still.. at 4500km though on odo lol.. and a daily drive consisting of a 6km distance one way, and 15 mins worth of traffic.... its killing me =[

[curtis265]

Oh shizz man! My daily commute is a relatively free running 6km too but i'm not getting those fuel figures... (i have the R18 btw, but it should still b similar)

[JOhnnyFD]

the R engine and K engines are different in terms of fuel economy.. the R engine are focused more on fuel efficiency

so obviously the FD2 with having a 2.0l instead of 1.8l would use more fuel

but srzly black8th, FD2's with climate control shouldnt be drinkin tat much.. prob either need to drive ur car more or sumthing... compare this to my friends evo7 2.0l turbo that runs 14-16l/100km

[curtis265]

^it's start-stop traffic in auto. that's disaster waiting to happen

[edmbranch]

black8thgen better start cruising around the highways and rack up the kms.. your engine's still tight.. it hasn't been popped yet.. you gotta pop it since it's your baby and all..

go test any fd2's around that's done more than 10k kms.. you'll feel the difference between both yours and the engine's that done 10k kms..

the fuel consumption should decrease to at least 10l/100km after 10,000kms..

[curtis265]

Do the K20Z2's get the vtec kick-in, Yo?

[edmbranch]

nope.. the crossover's not that noticeable.. however it's got more "pull" at the top end than the r18a.. speaking from experience..

[curtis265]

i thought K20's were DOHC?

and the R18 only had a vtec to slow it down?

[ekdez]

lol sounds so random.. its like the oppisite effect of vtec..
"only had vtec to slow it down"

[curtis265]

it does. srsly.

the vtec cams are less aggressive and engage when you have light throttle and ur between 1k-3.5k rpm. it's for highway usage.

[edmbranch]

yea k20z2 is dohc.. high lift cams engage at 5750 i think.. and redlines at 6800.. so that's 1k revs of vtec.. in that short period of time there will be.. however the crossover's not as noticeable in say a b16a/b18c..

[curtis265]

yehh why did honda hve to make things slower :(

[black8thgen]

yeah... once exams are over im gonna run this shit in lol

[liquid23]

i got 487km on BP ultimate. i had 3L left in the tank. A few hard goings as well.

[curtis265]

oh wow that's a lot of fuel...

9.65L/100km.

[.k.]

i usually get around 500/550 when fuel light comes on

[ekdez]

ran a 620 last fuel fill up =]

[black8thgen]

im so jealous.. SO JEALOUS

[curtis265]

me too! :O how'd u get 620 do u get a lot of warm-engine hwy driving?

i get too many short trips :(

[buddah51au]

I rarely seen the low fuel warning light come on under 600km when I had my FD1 Auto. The best figure i ever achieved was 5.8L/100km. but that car is long gone now

[black8thgen]

yea i get too many short trips cold in the morning, ruining my budget =.=

[fab4272]

oh wow that's a lot of fuel...

9.65L/100km.

To me that figure around town with alot of stop starts seems normal. My wife gets about 10 L/100 km around town only, no freeway or steady cruising. I thought that was a bit high until I saw the figure on Honda's website for around town only of 10.2 or something like that. I used to own a KH Verada and the trip computer used to indicate I was getting 12.8 around town, so the 2ltrs less sounds about right.

On the freeway the car gets nearly 700kms' per tank. Anyone that gets 500 and over must have a mix of city and at least some steady 70-80k driving as well. I don't believe anyone anyone can get 550-600 with ONLY city stop start driving, but thats in my opinion.

[curtis265]

^totally agree with you.

[SHU-ES1]

how big are you fd1 and 2 tanks? seems like you don't get much km's at all. filling up all the time would suck :(

[curtis265]

50 litres

[kizza42]

I'm pretty lead footed but do alot of HWY driving. Have been logging usage since november last year on my iphone. App is called RoadTrip.

The big spike of 20.2 L/100km is a night of hooning around Wagga Wagga doing a scavenger hunt with a full car. Found my best consumption of 6.9 L/100km sitting on 120kph in outback australia (Pushing up to a consistent 130-140 for a full tank (not bursts) pushed the consumption up to around 8-9 L/100km)

[curtis265]

wow 9.25 average :O You are lead footed.

[.k.]

omg forgot to keep puttin info into my fuel thing on iphone hahaa

[SHU-ES1]

thats awesome app for the iphone! how'd you take the screenshot?

[warwick108]

my average is 10ltr/100km.. its pretty shitting..and i stick in v-power

[.k.]

u hold home + lock button and it screenshots

[SHU-ES1]

awesome! cheers.

[.k.]

i've been trying out e10 lately.. what's everyone think? i get min 570km/tank - mostly suburban drivin not much highway so lots start stop nad a/c here and there

[curtis265]

lol i got 450 out of 91ron... and about 550 from premium

[ekdez]

i'd personally never use e10. ruins the life of the engine doesn't it..

[warwick108]

i really dont know how yous get these figures.. i get 400 from a tank of v-power or bp ultimate... i dont thrash my car aswell..and its 50/50.. free way/suburban..=S

[ekdez]

do you warm your car up in the morning? or start the engine and go?
i get approx 600 per tank too. from 98, synergy or vpowa

[eeKayFouR]

yeah well i'm doin about 2/3 tanks of this e10 then i'll see how many k's i get and compare it to 95 unleaded n premium 98 ron see what difference there is

warwick - you 50/50 normal and freeway and only get 400 wtf?

[warwick108]

start then go.. but i do not revv the car.. =S

[warwick108]

yeh.. i seriously think there is something wrong with my car.. i do not push it at all.. -_-".. out of a full tank.. i let vtec kick in about twice.. =S.. other than that.. low revvs all the way.. =S.. I use cruise control on the free way tho.. does that make a difference?

[edmbranch]

i get 400-450 from my fd1 nowadays.. i guess it's the cold that's reducing our milage..

running on cold engines..

[eeKayFouR]

not sure who else has felt it but when the car's on cruise control it doesnt feel as smooth as it is with ur foot.. when the road goes up/down it tries too hard to accellerate thus wasting fuel and even as its cruising along its pushin the car a little bit much =S

[warwick108]

yeh..i feel the same..but i drive home really late at night.. so i cbf looking at the speedo so i use cruise control.. =S

[curtis265]

i get 400-450 from my fd1 nowadays.. i guess it's the cold that's reducing our milage..

running on cold engines..

YEAH! my engine never seems to be able to warm up nowadays... I want summer back... actually autumn better...

[williamwong]

i let vtec kick in

vti = what vtec lol ?

[.k.]

the 1-3krpm fuel savin vtec lololol

[bodaas]

vti = what vtec lol ?

he means i-vtec and the more you kick it in the better fuel consumption lol

[warwick108]

the i-vtec kicks in at 2+ revvs.. but it doesnt mean it saves fuel, it means it eats less fuel than if i-vtec wasnt there..

[bodaas]

"VTEC-on on the R18A means it is running low cams. More importantly is VTEC engages the low-cams only if the right conditions for fuel economy are acheived. If they are never acheived, like when we are driving aggressively for the whole trip for e.g., VTEC will never open on the R18A. Thus it is a completely different idea from the VTEC implementations of old where VTEC will always open after a certain rpm, irregardless of the driving conditions"

fuel economy operating range between 1000 - 3500 rpm, i was wrong

[buddah51au]

The I-VTEC system on the FD1 is totally different to performance oriented VTEC systems. It is designed to work under low load with light throttle openings, the parameters being governed by the ECU alone.

Once you learn how to use the system the FD1 is capable of producing remarkable fuel economy. I had an FD1 Auto for 2 1/2 years & 60,000km, over which time I averaged 6.78L/100km with a best recorded of 5.8L/100 & a worst of 7.62L/100.

There is no noticeable difference in using 95 0r 98RON fuel, while using E10 decreases power by approximately 10% & at the same time increasing fuel consumption by around the same margin. So using E10 is false economy.

There are 2 things that govern fuel economy, 1 - The environment in which the car is driven & 2 - the way the driver uses his right foot. In the 2 1/2 years I owned my FD! Auto I never once had the low fuel warning light come on under 600km. Now as a Comparison, lets compare the Fuel Economy of my Current CU2 Euro Auto - just over 16,000km with an average fuel consumption of 7.2L/100km with a best to date of 6.47L/100km. So a current model Accord Euro uses approximately 0.5L/100km more than an FD1 Auto. I have spreadsheets available on all fuel used in both cars.

Have a read of this article.

wow 600kms per tank in an auto fd.

[warwick108]

WTF.. u can do 7.2ltres on ur cu2..wow...impressive mate. "i shall never beep the slow driver infront".. but instead.. i should follow him all the way to the city..=)

[bodaas]

the proper way to save your fuel
1. check tyre pressure
2. service your car regularly
3, avoid carrying unnecessary load
4. avoid traffic, use highway if possible
5. dont drive aggresively

my last tips are keep your fuel tank full, dont' try driving your car till fuel warning on lol, because the chance are the dirt from your fuel tank would flowing into your injector and blocking it.

[buddah51au]

I go the opposite way, I wait till tow fuel light comes on (or close to it) so I always have fresh fuel & I have never had a prob with blocked fuel filters or dirty injectors

[buddah51au]

wow 600kms per tank in an auto fd.

600 was the norm ..... no wow factor in it, from memory I passed 700 a couple of times. Note I still have the spreadsheet on economy for my FD1, anyone wants a copy just pm me your email add.

[buddah51au]

WTF.. u can do 7.2ltres on ur cu2..wow...impressive mate. "i shall never beep the slow driver infront".. but instead.. i should follow him all the way to the city..=)

It's not a matter of driving slow, but how you use the throttle. I always drive at the posted speed limit in daylight, drop back a little at night due to wildlife on the roads. Note 7.2 with the CU2 is an average over 16000km, several times I have been under 7L/100km. It is possible to do 1,000km on a tank with the CU2 ..... that is WOW ....lol

[FallenAngel]

the i-vtec kicks in at 2+ revvs.. but it doesnt mean it saves fuel, it means it eats less fuel than if i-vtec wasnt there..

Incorrect but as bodass has said

i-VTEC is activated when not much fuel is needed hence runs on lower cams. It ranges between 1000RPM - 3800RPM.

i-VTEC may not engage depending on how you drive. If you got a heavy foot then more than likely it will never engage because the car thinks its never needed to go to the lower cams because you keep using the power the car has.

I do notice sometimes when crusing on a freeway, if you need to overtake there will be a slight "bump" in the engine which is the cams changing back over to the norm so that power is achieved. Its a very slight bump but some of you guys might have noticed it as well.

[buddah51au]

2006 R18A
3-stage VTEC
Examine the SOHC VTEC and SOHC VTEC-E implementations. The clever Honda engineers saw that it is a logical step to merge the two implementations into one. This is in essence the 3-stage VTEC implementation. 3-stage VTEC is implemented on the R18A 1.8 SOHC engine in which the VTEC-E mechanism is combined with the power VTEC mechanism.
Many of us probably has laughed at the poor ignorant layman who said "I want power AND economy from my Honda". We know of course that power and economy are mutually exclusive implementations. Honda decided not to abide by this rule. Now, with 3-stage VTEC, we get BOTH power and economy !.
The diagram below illustrates the 3-stage VTEC implementation. The intake rocker arms have two VTEC pin actuation mechanisms. The VTEC-E actuation assembly is located above the camshaft while the VTEC (power) actuation assembly is the standard wild-cam lobe and rocker assembly.


Below 3500rpm and with gentle accelerator pressure, neither pin gets actuated. The engine operates in 12V mode with very good fuel combustion efficiency. When the right foot gets more urgent and/or above 3500rpm, the upper pin gets actuated. This is the VTEC-E mechanism at work and the engine effectively enters into the '2nd stage'. Now R18A 3-stage works in 16V mode (both intake valves works from the same mild cam-lobe).
Stage 2 operates from around 3500rpm to 5200rpm. When the rpm exceeds 5200rpm, the VTEC mechanism activates the wild cam-lobe pushing the engine into the '3rd stage', the power stage. Now the engine gives us the full benefit of its 140ps potential !
The 3-stage I-VTEC R18A engine is used on the current 8th generation Civic. The 3500rpm cutover from lean-burn to normal 16V operation in fact varies according to load and driver requirements. With gentle driving, lean-burn can operate up to 3500rpm or higher. The essence of 3-stage I-VTEC is power AND economy implemented on a 1.8l SOHC PGM-Fi engine. Many people mistake 3-stage I-VTEC as a "superior" evolution of the power oriented DOHC VTEC implementation, describing DOHC VTEC as "the older 2-stage VTEC" and implying an inferior relationship. This is totally wrong because DOHC VTEC is tuned purely for high specific output and sports/racing requirements. 3-stage I-VTEC is in truth an evolution of SOHC VTEC and VTEC-E, merging the two implementations into one.

off course you never had a problem unless if you put rocks inside your fuel tank hehehe. so if you like cleaning up all the dirts from the bottom of the tank then you should do it regularly

my opinion to keep fuel tank full is also to avoid the air going to much into your full tank. The reason is because unleaded fuel can easly be vapourised into the air. I used to clean my cylinder block with unleaded and air compressor so i know

in my 40 years in the motor trade petrol has always been used as a cleaner, there is nothing better for cleaning engine components. Fuel will not vaporize if it is correctly sealed.

As for putting rocks in a fuel tank.....that's a new one on me. what advantage would you expect to gain?

There is an advantage it makes you understand what's the different between now and problems on the long run. If you want to see the problem now just grab a fistfull of sands or rocks and put it into your full tank then drive it till your fuell warning is on lol

Anyway each peoples have different opinions if you think your's opinion are better and recommended then do it noone will stop you :thumbsup:.
