i have to. i ran like a gallon or so of regular because i ran out of gas once, and it ran like crap. the manual says premium too. i wouldnt if i didnt have to believe me. still, i wouldnt trade my high compression for anything.

 

Hey, no problem. I'll trade you even up for my '98 auto-trans F23 which takes REGULAR!

 

Does this make any sense: Running regular in a vehicle that requires premium can foul an oxygen sensor? I think I read that somewhere once... what about running e85 in a non-e85 car? my girlfriend filled her neon up with e85 once....i dont think it hurt anything severely

 

Regular vs. premium shouldn't have any affect on the O2 sensor.

E85 can cause problems with deteriorating rubber seals & stuff in the fuel system. And corrosion from themoisture that's usually carriedalong with theethanol. But I think that's long-term. Using it once might not do anything bad.

 

as tempting of an offer that is, i must decline [sm=gobble.gif]
