High fuel consumption issue

by **Mr Cali** » Tue May 31, 2011 9:17 pm

Hi, it seems as though I have a problem with fuel consumption. I only get around 360-380km per tank, usually about 55+ liters when I fill up.
I only use 98 octane fuel and probably do 80% peak hour traffic driving.
I have replace the AF (yellow) sensor and that has fixed my miss on idle but that's about it.
There is no engine/ecu light coming on and the car is still very smooth and accelerates nicely. It has only done about 85k on the clock

What else could it be? I think I read somewhere about blocked cats causing very high fuel consumption, could this be the reason and is there a way I could check this without taking the exhaust apart?

For the driving conditions (peak hour) id say thats a pretty normal figure. I get similar figures around town.

When i drive into town in peak hour my fuel eco goes from 9L to 13L.

Same for me 12-14 around town, even higher if it's stupid city traffic and I'm 'impatient'. Normally it's 10.6 combined, right on factory spec.

im thinking it must, if im only driving around town, and lets say i was late for work, and driving less smoothly than normal, i can get it up to around the 14's pretty easy.

heres to hoping a tune soon will help this.

I use about 10.2L/100km and I have a dump pipe and some other intake stuff with no tune, and I do drive in a bit of peak hour also.

It's cos they are fully hectic and so much faster…

That and they run very rich from stock and are tuned more aggressively than a 2.5. Also 2.0 pulling all that weight doesn't bode well for fuel consumption!

And, Kieran your intake mods will be making your car run leaner, hence less fuel as well.
