Euro fuel consumption

[cdbstock]

Have a 2006 Euro Luxury Nav.
Getting 14 l/100 km - mainly urban, short runs
Honda says car is ok (warranty claim re consumption) - even though I paid for a dyno test indicating serious fall of air fuel ratio
Other forums indicate should be getting at least 9.2 l/100 km
I am 64 & a sedate driver.
My previous Euro gave excellent consumption - 6.5 country & 10 average
What consumption should I get & what do you get?

[Ken-f]

Are you auto or manual? I think 10-12 is is normal for auto urban driving. I drive manual, when my compressor died, i got as good as 7.8. Recently, its been getting worse. About 9.5 for manual. So I don't think you have TOO much to be getting worred about. Have you tried using premium 98 fuel?

[yfin]

there was a wheels test I read once that did show the auto euro getting in the 14s for only city driving. Definately not in the manual though.

[aaronng]

Could you show us your dyno chart?

[hughba]

If your AFRs are all over the shop I'd look at swapping your oxygen sensor(s). I'm not sure but I assume these cars only have one. Try getting your hands on one you know is ok and trying that.

[cdbstock]

THANKS FOR RESPONSES
YES IT IS AUTO
HAVEN'T TRIED 98 BUT MANUAL SAYS USE95 - & 98 IS DEARER THAN 95 0 BUT WILL TRY IT - THANKS
I'LL POST DYNO CHART WHEN I WORK OUT HOW - I THINK I CAN
WAS THE 9.5 FIGURE ALL URBAN? ADD 10% FOR AUTO & A/C - YOUR RATE WOULD BE APP 10.5
MY READING TELLS ME THAT AN OXYGEN SENSOR ONLY CORRECTS VERY MINOR DEVIATIONS FROM STOICHIOMETRIC - +-5% I THINK & IS OUT OF CIRCUIT (OPEN LOOP) AT MEDIUM TO HIGH ENGINE LOADS. aS THE CAR IS UNDER WARRANTY, I HESITATE TO FIDDLE WITH THE O2 SENSOR - BUT A SERVICE TECH COULD

[cdbstock]

Sorry moderator - I used all caps last post but will use lower case in future

[cdbstock]

Moderator - thanks. App 26000 km. bought new. Previous Euro was bought new - Good suggestion re injectors

[flipmods]

Yeah sounds high. I have a 2003 manual and I hammer around the city and still get in the 9's/100L. Definately something wrong if intake, exhaust and rest is stock. Goodluck.

[Crapdaz]

it really depends though if he does alot of mileage from short trips < 10mins drive and few times a day then obviously that is going to kill your consumption.

e.g Had a work mate who had a 2007 commodore and was complaining why he got 20-23L/100km, ended up being his wife cause she does alot of 5-10min trips each day.

Show us your dyno graph to see fuel ration might be running rich or something wrong with the o2 sensors as stated previously.

[tron07]

when I putt around the city, usually like 20 minutes drive in stop and go traffic crawls, I get like 11.5-12 on the trip computer..... if highway cruises, I get like 7. Manage to get 6.7 once, going 90kmh on 6th gear.

[Crapdaz]

cdbstock are you basing it on your average/100km on the dash display right?
because if you do the calcs the average for a number amount of tanks of fuel you've gone through which is inaccurate but is an estimation.

My suzuki swift is rated 6.1l/100km but the clock read 10.8l/100km.

Assuming if you don't do this for future fill ups (please disregard if you do calc)
Next time calculate by the fuel receipt and before fill up zero your clock.
(Amount filled up (X litres) divide by number of KM's on the clock) multiply by 100 = mileage per 100km
For example: (55litres / 600km@filluponclock)*100 = 9.167L/100km

What fuel you pump into it and what mileage do you get before fill up?
Are you using "SHELL UNLEADED or Vpower" ? If so try another brand like Mobil Syn 8000 or BP Ultimate

[aaronng]

Actually thinking about it now, a dyno graph won't prove anything because that is at full throttle which relies on the fuel maps and not the O2 sensor. Your best bet would be to get a known working Euro primary O2 sensor and swap it over for a few weeks.

[hughba]

Exactly. If the O2 sensor is shagged the ECU often reverts to the richest mixture it can. It doesn't just make plus/minus 5% changes. It's the simplest thing, so start with that.

If it's still funny, take it on a highway cruise at 110 km/h for a few hours and see what your economy is. That figure will be a lot less variable.

[tron07]

you dont need a few hours cruise to tell you that..... a 5-10 minute drive would do the trick. Drive on a highway at 90-100 constant and reset the trip, after 5-10 minutes, you should know the fuel consumption

[oat.iphone]

hey, just a simple add to this, i run euro 2006 lux/satnav too, usually do 5-10 min/trip every morning to drop my gf off, my meter was reading around 12-14 Ltrs/100 Kms too

it seem like even if i drive slow like 50-70, my meter was reading around 12-14, but when i rev its the meter seem to remain the same or sometime even goes down by like between .1-.3

is there something wrong with my o2 sensor too?

PS: i've never run euro before, hence i don't know what the average for this, [ MY CAR IS AUTO], but according to the adv it said euro only take about 8.9 ltrs / 100 kms

[cdbstock]

Thanks craddaz & flipmods & tron7 - my consumption figure is from calculation - the 'i' indicator seems to correlate reasonably. Will try 98 (S8000) next time - using S6000 now. Havn't tried Shell.
Honda says poor figure must be due to my driving (short runs & cold starts) - I will keep a log of trips next fill up.
Re the dyno chart - I'll try photographing it (digital) & with advice as to how, I'll post it. Honda wont release their dyno charts so cant compare.

[cdbstock]

Looks like I need it (good luck)

[cdbstock]

I'll try that too - thanks
My dash indicator seems reasonably accurate but my figures are based on calcs;

Mainly from short drives mate.

Sounds like the same scenario as i posted above; as my work mate, his wife drives down to the shop which is like <5mins and back up; then followed by picking kids up from school every weekday.

Reset your average fuel consumption and use that number over a whole tank. The instantaneous fuel consumption is not a good indicator of your average fuel consumption.

My son says to reset the ECU by pulling a specific fuse for app 20s - possible a bad fill may have caused ECU to change setting to compensate - but ECU setting have been checked as ok - if I do a reset is it necessary to have key turned to ignition?

[Crapdaz]

pull negative terminal out for say 5-10mins.

It will refresh the ecu but will relearn your current mixtures etc.

I would then have to use radio code-I'm sure I have it somewhere - but pulling a fuse would be better if it does the same

[Crapdaz]

if i recall the euro doesn't have a radio code, just need to reset the time though.
only thing is i am not 100&#37; sure on the satnav version of the car.

[aaronng]

No radio code, but the sat nav will have to spend a while recalibrating. You might even lose your saved locations.

[yfin]

Was that a full throttle run as the horse power looks too low - even for an auto.

Looking at that dyno chart I also wouldn't expect the Euro to run as lean as 14.5 - then when vtec cuts in it looks like it runs too rich. Weird.

could that be why his getting massive fuel consumption

wtf 122HP isn't that like 89.7kw ATW.
hmm... something seems wrong doesn't the euro run 100kw atw minimum?
like a 40&#37; loss through the transmission to driveshaft.

[aaronng]

First question to ask is if his dyno is the green or yellow line.

[Crapdaz]

rofl...... :)

[aaronng]

I hope it is the yellow line, but the yellow line seems to have like 2000rpm worth of highcam

[Crapdaz]

But don't you think the power seems a bit low?
wonder what gear he ran it in.

[cdbstock]

I hope it is the yellow line, but the yellow line seems to have like 2000rpm worth of highcam
The yellow lines are full load HP & full load AFR

[cdbstock]

But don't you think the power seems a bit low?
wonder what gear he ran it in.
Its auto so I assume it's all gears up to 110 kph. I also assume the run would have reached higher HP at higher speeds but the test run was terminated at 110 kph. What HP (kW) ATW should I get as maximum? - the advertised engine power is 140 kW

[cdbstock]

hmm... something seems wrong doesn't the euro run 100kw atw minimum?

I assume quoted power (140 kW) is without any accessory (alterator, power steering, aircon, water pump) - so loss via power-train would be less than the 40&#37;

[Crapdaz]

i would thought they turn it into tiptronic into 4th and run it until cut off which is 7200rpm.
For stock i would assume you'd get around the 100-105kw atw mark from previous members who dyno'd it stock.
Your 122HP would = 122/1.36 = KW value. Which when i calc'd is 89.7kw ATW.

[cdbstock]

From your replies I get the message that something is wrong somewhere. I will try your suggestions & if I can prove to a court that the car has a fault I will ask Honda to fix & pay my expenses in proving it or proceed to court if Honda wont.
Thanks to you all

See what other ppl say, i don't have an auto myself so i'm not sure how they do the dyno for them.

I may be wrong and that the auto has a larger power loss than the manual.

[Min988]

Where did you get your car dyno'ed?

[buddah51au]

From memory the KW loss ATW on a manual is around 25&#37; (average), on an auto average is 30 to 35% depending an design of auto tans

[hughba]

Dynos vary so much it's not always wise to get caught up in power figures. Also, if it was done on quite a hot day I would expect it to be down on power.

This is a hard one to diagnose if it isn't throwing fault codes. Usually when O2 sensors or TPS goes you get fault codes.

It could just be the short trips - it really does take it's toll. Especially if you're stuck in traffic.

Any other symptoms?

[aaronng]

I wouldn't be hung up on the dyno power results. Looking at the partial throttle, you are getting about 14.5:1 AF ratio, which is typical when with light load. Did you manage to do a run with almost no load? So the speed/rpm won't change, but you're just keeping the car's wheel speed constant. That's closed-loop mode where the ECU relies almost totally on the O2 sensor to determine whether more fuel is needed.

[Rob_A]

Thanks craddaz & flipmods & tron7 - my consumption figure is from calculation - the 'i' indicator seems to correlate reasonably. Will try 98 (S8000) next time - using S6000 now. Havn't tried Shell.


Don't bother with Shell. I had my worst ever figures with V-Power. They use ethanol to get the mixture to 98 RON. I average 7.5-8.5L/100kms on vortex and have been for the last 9 months. V-Power I topped out on 10L/100kms. With V-Power your better off using Shell's E10. Talking to my mate who deals with the refineries through his work, Vortex is the best, followed by Mobil 8000 then BP Ultimate.

Rob

[Sp00ny]

Your figures definantly seem high for a car with such low kms and subtle driving habits. I know the auto definantly does go through more fuel (I have compared them). I have an '05 Luxury; 97,000kms; Fuel Average Hybrid 8-9L/100Kms (City and Some HWY), and filled up with 50 litres (bit before fuel light) and have already got around 410 kms and needle is still just above half. I drive conservatively, very rarely go past 4,000rpm. I use BP Ultimate.

For such high figures I would be looking at a few things. If your keen to do some simple DIY testing, it would be wise to look at things that may affect your fuel ratio but not enough to trigger an ECU Trouble Code.

Get yourself a can of electrical Contact Cleaner.

- Clean MAP Sensor (Located on the front of the Intake Manifold)
- Inspect Oxy Sensors (Professionally Test them)
- Inspect Air Filter Element
- Get your ECU read at Honda or reputable mechanic if you haven't already.

I would be looking at a possible faulty/contaminated MAP/MAF sensor first and go from there.

Also Inspect your spark plugs and report back the colour.

White: Lean, High Temperatures (Incorrect Plugs(need a colder plug)/Lean AFM)
Grey/Light Brown: Stoich (Running Well most likely)
Dark Brown/Black: Rich (Rich AFM Issue)
Black/Soot/Fouled: Running Very Rich or Burning Oil.

If you live in Melbourne, I'm more than happy to help out.

Remember: The key to fuel efficiency, the majority of time is how you drive. Shift at optimal points (difficult in an auto though) (mine are around 3-3.5k usable torque starts at around 2600rpm) and low throttle. High RPM or Anything over one quarter to a half throttle will unnecessarily use more fuel.

[aaronng]

Shell Vpower does not use ethanol to reach 98 RON.
It is Shell Vpower Racing that uses ethanol to reach 100 RON.

Rob

As above. Shell don't use Ethanol in V-Power, if they do then they would have to state it to avoid legal ramifications. Also I have a relative that works for Mobil and he says BP Ultimate is above all, it is "cracked" at 98 RON (same as what aaronng told me a while ago) and is very clean. He said Caltex/United fuels are of a much lower standard/quality than BP/Mobil/Shell.

The only issue I have with V-Power isn't so much Fuel Efficiency, it's cleanliness, it produces alot more dust/residue compared to BP/Mobil. It also changes the colour of my spark plugs. These tests where done in my old Integra, not my Accord. When I tested them all in my DC2 I found Mobil 98 gave the best Kms just over BP but BP was the cleanest. Both Caltex and V-Power gave similar k's (about 30-40 on avg less and left ALOT more residue/soot than BP/Mobil.

[hughba]

Even a cynic like me can't ignore that so many big manufacturers support BP Ultimate.

I'm sure they get paid to do so, but I still doubt companies like FPV would be willing to write recommendations on the fuel flaps of their cars unless they thought it was halfway decent.

Looking for a volunteer:-
Have a 2006 Euro Luxury auto.
Have major problem with excessive fuel consumption - app>14l/100km
Having problem with Honda Aust - wont accept there is a problem even though have dyno & AFR chart indicating major AFR problem.
Need a similar Euro auto achieving near published consumption to compare dyno & AFR - I'll pay. Volunteer would help me determine if my car has poor AFR & get a free dyno & AFR chart.

what's your AFR no.?

[ewendc2r]

Hi guys -- This is my dad.. (CDBSTOCK) ..

I've gone through a lot of different items with him, and its going to be a hard one to test / find fault.. (As above, no ECU Codes being thrown)..

Dad -- I'm sure someone will have a stock DYNO floating around (as mentioned in this thread, there have been stock dyno's carried out in the past) so no need to pay for someone else to get a dyno (in my opinion).

The best way to fix this long term is simply get aftermarket management so you can tune it (and know exactly what AFR's are being thrown out).

Since you don't drive your car with any sort of recklessness, I would think that by getting a tune with K-Pro or similar, you would be able to tune for economy rather than power (as most people do).

What are thoughts out there? Stock ECU is always a compromise between power and economy. As much as we can tune to get more power, surely we can also tune for more efficiency?

Interesting point above about the MAF/MAP sensor -- Worth looking at, can get dirty relatively easily...

Now -- To get more than 300kms a tank out of my Type R, thats a challenge lol.

[Crapdaz]

hey..

how many short trips do you do? trips that take less than 5-10mins?
e.g pick up kids, or go down to shops etc.

I know a work mate who has a commodore VL or something 2007 model.
On highway and suburban with him driving it'll be like 13-14L/100km but with the wife (picking up kids, shops etc alot of short trips) was pulling 20L/100km.

Sp00ny does this mean that buying Vortex 98 is nowhere near as good as BP Ultimate 98?

That's your reason for killer consumption.

:thumbsup: If you do only short trips without any long trips, then the fuel consumption will be higher because it is not cancelled out by the longer trips.

[buddah51au]

Fuel consumption is dependent on the conditions the vehicle is driven under & the right foot of the driver. Give me the car for an hour & i would lay odds i could get it under

7l /100k.....short trips kill economy

Just filled up last Tuesday and before that, I did a routine photo before heading out to Caltex

during this last fill up:

-the fuel gauge reached exactly half mark, $31 of 95 Premium
-I did alot of short trips
-tyres were pumped up as usual every time after I fill up, at 230 front and 220 rear (kPa)
-had some rainy days with air con on, and occasionally 2 or more passengers
-did not VTEC the car, nor shift over 4000rpm (yeah my mind's gonna blow :p)
-I short shift alot, go easy on the throtle
-always try cruising at 2000rpm (1500rpm on downhill or extreme flats)
-serviced the car last month, mechanic changed engine oil, cleaned the K&N panel filter and replaced the oil filter

so ended up racking up 268.1km

how's that compared to everyone?... disappointing really... maybe in the market for a 1.8...

[eg_08_wa]

since owning my car in april 2008, i've always pumped bp ultimate 98. first couple of tanks, barely managed 580kms per tank (i have never filled more than 59L). after 2 months, fuel consumption bettered and i got easy 650kms per tank.

my average now hovers round the 650kms mark give or take 20kms. this is all dependent on my right foot, and types trips.
i average 80kms a day, most of which is hwy kms. shortest trip is 7kms, done atleast twice a day. fuel consumption doesnt change if i run aircond or not. i've run a/c from full to empty and still got the same result, around the 650kms mark

my best tank was a country trip, where i got 780kms from a full tank and that was with a/c on all the time. this was kms a half tank: half tank (http://www.facebook.com/photo.php?pid=1868447&id=734783505)

also, anything below 2000rpm may not be helping u save fuel, cause your car doesnt have enought power to move, thus end up using more fuel to get motion happening. best to stick around the 2000-3000rpm range. that way it is atleast withing ur torque range and power range, so you're not loading your car as much.

[ewendc2r]

I'm going to check in other areas of this forum -- I think you need to go to Dyno thread.

How many litres did $31 buy you?

I just filled up last night. Put in 47.49 litres and had driven 545km. That gives me 8.7L/100km. I do 10 minutes freeway and 15 minutes slow road (60km/h + 2 school zones in the morning at 40km/h) each way everyday.

[Crapdaz]

$31 means nothing.............. puahahahhaa

[Blitzen]

ha! yeah I barley use the car, only for Friday nights and weekends. I've just found the receipt and it's $30.95 woth of petrol including discount got me 26.34 litres, I filed up on the 5th this month and it lasted me for a whole week till the 12th

But I remember I had quite some fuel left in the tank before that fill, but it was cheap Tuesday so the fill up made it to half a tank on the gauge, which is probably 30 litres?

but yeah... my short trips is killing fuel consumption, maybe I'm better of driving a smaller car :P

[buddah51au]

that is no way to measure fuel consumption and means nothing

So you didn't fill the tank up til the pump stopped on its own? Without letting the pump fill to the top, it is difficult to calculate fuel consumption with any accuracy, like buddah51au pointed out.

Thats like saying it cost me a little over $70 to fill the tank this week, it tells no one about accurate fuel consumption. On the other hand if i said i used 58.57 liters to travel 844km people can use a calculator and work out from that tank of fuel I got 6.94L/100.

Then i guess i would draw comments like impossible, some may ask how do you manage that, others may even think I am evaluating a Diesel CU2.

Yeh blitzen !!! :)

during this last fill up:

-the fuel gauge reached exactly half mark, $31 of 95 Premium

how's that compared to everyone?... disappointing really... maybe in the market for a 1.8...

In your terms,

From Full to Half I get about 370km. From half to yellow light (bit more than empty). I get about 270km. Don't be cheap :P, fill up a whole tank then measure the K's. The first 'half' always lasts longer.

Oh yea, im 6MT

27/11/2008 - 25.22 litres = 200km = 7.9km/litre = 12.6L/100km?
1/12/2008 - 27.8 litres = 240km = 8.6km/litre = 11.6L/100km?
9/12/2008 - 27.8 litres = 245km = 8.8km/litre = 11.4L/100km?

last year's figures, I would fill up everytime the fuel gauge reaches the exact point in the photo I posted on previous page, these figures were recorded after resetting the ECU and before servicing the car, cbb to measure fuel consumption since returning from holidays, will continue records now.

Not sure if I missed it, but is your car an auto? If it is, those numbers (11L/100km) is typical of an auto Euro driven in only city conditions.

yeah Auto, just had a quick glimpse at the fuel dockets for the amount of fuel I purchased and the distance travelled so far, I have a feeling there will be improved figures after servicing and changing my driving style, will update soon

Just back from a trip to Melbourne in my CU2 Auto, aircon on all the way and mostly on cruise, I stayed four days in the CBD and had to navigate in and out of Melbourne each day for sight seeing. Did 2600km from my door to return and finished with 7.8 litres per 100km.

I have my trip computer set to restart the A meter when I tank up, the B meter was started when I left Sydney.

The shot below was taken twenty minutes after filling in Melbourne and cruising west on the freeway at a 100km. A little while later in dropped to 6.7 before we hit some road work and it was gone.

That trip computer looks cool. Does that screen come up on the navigation unit? Does it still have the trip computer on the dash under the speedo?

That’s on the Nav screen and yes it still has the trip computer on the dash.

It looks cool yes, but can you see a button or instruction to change what your viewing?

Its not there! The dash is so much more functional.

I rarely do any freeway driving but I made a trip this morning from home to the Melbourne International Airport. I reset my trip computer once I entered East Link did a drop off at the airport without stopping the car then back home again. I stopped my measurement once I exited East Link. Getting 5.4L/100km over 106kms isn't too bad for an Auto not using cruise control.
