have a 02 m3 i fill it up super or mostly ultra 94 getting 330 kms to a full tank. wats wrong with my ride wat ae u guys doing toa tank please m3 owners respod thankz.
hi i have an 03 m3 and get about the same crap depending on how i drive. if i keep the shifts below 4000rpm and dont stopm the gas pedal or put it to full throttle at all, with 50% hwy driving i can get about 500km. But if i have fun with the car i get about the same as u. For some reason if i run any less than 94 octane SUNOCO and push the car my check engine light will turn on code reads cataletic converter, so i dont run less then 94.
