I noticed since in got colder I have been getting crappy gas mileage. Last week was normal, I used 93 octane and got slightly lower gas mileage with the colder weather. I used 89 saturday and todays tuesday, ran 176 miles, now on half tank, holy crap! Either my Bonny hates the colder weather, I got some bad 89 gas (runs fine though) or theres something really wrong going on here. I used to be able to get 250 or more miles before I reached Half tank. It has dropped to the 40'* and 50'* this week, cold

Might also be your Oxygen sensor on the way out, that contributes to poor economy, as well as a dirty fuel injection system

i usually get over 300 on a half a tank (even with a heavy foot)

me too im at 159 and im at a half tank i usesally get 200 or so. and ive been grandmaing it. i just replaced the o2 sensor. dont feel bad im getting bad gas mileage too i feel ur pain

I just bought a new oxegen sensor 4 weeks ago. Its running great, just this week its eating like theres no tomorrow. Can running a higher octane fuel for a week then putting a lower octane fuel cause this.

89BonnieSE89, I think your right about dirty injectors. I just remembered before I filled up saturday I ran the tank almost dry. That could very well be it.

I get about 250 miles to a tank if I take it easy. Otherwise it'* usually 210-220ish.

About 12mpg.

A friend of mine at work told me it depends on where you buy the gas also. I bought this tank at a Sheetz and he says he get way better gas mileage at Exxon. So I guess what I am going to try is put some injector cleaner in and fill it up at and Exxon and see what happens. This car used to get about 430 miles per tank!

The */C eats mine.

My right foot eats mine. I've gotten 380 once, but i'm normally around 300 with the way i drive. After starting off this last tank last night with seth i wasn't exactly grannying it up to the govenor.....
