OK, I have been watching my fuel milage for some time now, and I see a disturbing trend. My car has 2,500 miles on it. Until about a month ago, I was getting appx. 240 miles per tank of gas and about 17 mpg on average with probably 80% city / 20% highway driving. However, for the last 3 tanks I have only gotten about 170 - 180 miles per tank and the fuel economy has dropped to less than 13 mpg (according to the computer...yeah, I know its not accurate, but this is a before and after comparison). In the beginning, obviously I was breaking the car in, but I don't believe my driving style has changed real dramatically, in fact on my last tank I tried to drive conservatively to see the results (I think I got about 190 miles on the tank).

Has anyone else had this problem? I didn't buy this car for fuel economy, but 12 mpg is a bit ridiculous (many SUVs do better than this). What gas milage are others getting?

wil drop your mileage by 12-15%.

plus, I think MTBE added to gasoline decreases mileage and performace. Anyone know for sure?

Soulds bad, I get over 200 per tank, highway only I get over 300, so far. W/MTM

Possible oxygen sensor failing? Just a thought.

Last two tanks have been about 26.5 mix of city and highway.

MTBE cost you both power and fuel mileage

Not sure about MTBE usage though.
