Question about unusual fuel consumption
Hey I have a 1991 318is w/ 183k, and I have always used 93 oct. Lately, I have noticed I average around 110 miles per tank. I have looked for leaks and havn't found any. I am a "spirited driver" but 110 miles per tank seems abit ridiculous. Any ideas on what could be causing this dip in gas mileage?
-THX!

When was the last time you changed your O2 sensor? Tire pressure? Tires? Brakes? All of the above can affect MPG.
