Horrible Gas mileage.....

I seem to be getting only 225 kms on a tank of gas. Is that normal given the mods that I have (Sig)??

I thought that I should be getting at least 300kms per tank.

Any thoughts??

BTW....I changed the plugs, wires, fuel filter, and PCV valve less than 1000kms ago. The car runs strong with no hesitation, and there is no vac leaks. I should also add that the car still has the original O2 sensors. Would a tired fuel pump cause this?

IMO a tired fuel pump could give better gas milage because it is so damn tired of pumping that it slows down. ... jk.

O2's could be a culprit or it could be the 'foot2floor' syndrome that comes in association to your mods!

Seriously O2's can make a difference.

Thanks. I will be changing the O2's next week along with a new 255 lph pump. Hopefully the gas mileage will get a little better.

I'm with you Steve my fuel milege sucks I think some of it at least is the foot to floor syndrome but I have tried to be civilized for a tank and don't seem to get any better milege.
