Going through gas way to fast.
I have a 96 z3 1.9, and lately i have been getting some garbage numbers when it comes to miles per tank. I remember when i was younger me and my father use to be able to get at least 300-350 miles on a tank, but now, i am barely getting over 200. Do you guys know what this could be? I have read some guys saying that it could be the o2 sensor, but is that the only thing it could be? Could there be other things wrong with my baby to?
Any help is greatly appreciated.
