any one else have issues with slightly rich???
mine occasionally has a fuel smell (no leaks that i can find) and uses slightly more fuel that i would expect 9-10L/100km??
where should i start?

My m13a vvt has been using lots of fuel Lately and you can some times smell petrol when its idling. Turns out my Egr valve was fuked. It got fixed today....not sure how you would check the Egr valve tho...

[zooky08]

I go through half a tank in two days

[jonno_racing]

how many km's? i get OK mileage..

my fuel usage doesn't seem to change if i am going easy or giving it a bit of a hard time

[jimny_timmy]

I'm getting about 8.7l/100kms around town etc, but 10ish fully loaded or wheeling. Mines VVT though.

[zooky08]

Roughly 130Km

WTF !!!!!

im getting 450 if i drive normal or 530 if i baby it

[zooky08]

Mine drinks it like a thirsty camel even if I be sensible. I fill up every 4 or 5 days.

[woo603]

when was last time you cleaned air filter, checked spark plugs, etc
not being a smart arse but 130km just doesn't sound right.

[zooky08]

New aircleaner was put in a month ago. Not sure about spart plugs. Most I have got out off a tank would be 350km

[woo603]

have a look at your plugs when you get a chance
also may have a to look into you oxygen sensor (O2 sensor) if that is gummed up with shit or its starting to die then that may also cause some issues

(if im wrong please correct me)

I'm lucky to get about 300kms around town. (and I try to baby it) I can't smell fuel...seems like everything is ok. Perhaps not.

(2010 1.3VVT)

235's will do that tho these guys are running 215's...

[31zook]

I'm getting about 300kms from 235s and stock gearing. I drive pretty slow tho....

Was about 400-500kms with roadies on.

[jonno_racing]

maby its about right then?

tha fuck! r u two vvt???


mine with 215s i only get 300-350 .... even when have stock tyres was pretty much the same

speedos are rarely accurate,
especially with taller tyres,
so you may be getting better economy than you think.

But yes, raise body position adds wind drag,
and taller tyres add weight and rolling resistance.

Off road capable cars will never be road warriors.

Nope G13bb all the way

It was pretty good on petrol. Better than my sierra!

[JrZook]

Are you guys that are worried about your apparent crap fuel economy correcting your odometer readings for the larger tires before working out km/L?

[zooky08]

I'm none vvt as well, but my car is 20 foot in the air so I have wind drag like Chris said
My fuel economy is heaps good offroad though
I can do a day worth of 4wd and the gauge doesn't move much.
I sit at 4100rpm at 100ks. Jimny like to rev.
I'm trying to lower my rpm. 3900 would be good I reckon.

I know all that.. we re talking bout the reading of the speedos without correction.... and we having same kind of tyres they re getting far more than me

and I only have 45mm lift, so is not really that much

and like I said, when I was stock (suspension and tyres -205/70/15) I still have the same-ish crappy fuel eq (300-350km)

not worry bout that, Im worry bout how come they can get 400-500km ?????....... I get the gauge till the red mark.... prob ill still have an extra 5-8lt in the tank on that point, but still

[jonno_racing]

my figures are tps corrected

Ah yeah! It's all in the roof rails

My speedo is about 5kms out....

[gjb977]

Mine just has the 80mm TD springs/shocks and 235's so not overly high.

Before I added all the shit I've added in the last 12 months, mine easily did 450kms not babying it! I reckon I could have gotten 500+ out of it back then. Did a trip to VIC for new years, and fully loaded with swag, and a bit of stuff on the roof, I got around 10.5l/100kms, at round 35l of juice per fill...350ishkms give or take. Thats also with a bullbar,winch, 40mm lift and like I previously mentioned all the gear on the roof!

Bert, you're climate may play a little role in yours (heat and humidity etc) but I wouldnt guess that much, but Phil, you definitley have something wrong if you can smell the rich fuelly smell!

Dude if you really think about it, if you had even 5 useable liters left in the tank and using around 1L per 10kms, that's an extra 50k's added onto your 300-350.

If you really want to check your actual fuel economy accurately go to the servo, reset your tripmeter, fill the tank so its absolutely full ie not to just when the nozzle stops but when you actually can see the fuel level at the filler neck, go use your car till nearly empty, then go back to the servo and re-fuel till its absolutely full like before. Record the tripmeter k's and divide by how many liters the car actually used.
