I have noticed lately that when I really get on it I can see right much smoke in my rear view mirror from the exhaust. Does anyone else notice this? I expect some but it just seems excessive. I use 93 octane gas but it is usually the gas from 7-11. Could this cause it? Should I try Amoco or Mobile gas? Anything to help keep the smoke down? Looks like crap when people behind you are left in a fog.

 

what color smoke? If it's black, then it's fuel related, if it's white take that **** to the dealer and get it checked out under warranty

 

No, it looks black to me.

 

I use 93 mobil gas if you wanna make that switch, had no problems yet. the only smoke I get is from the cold while I warm it up in the morning...........

 

I use 89 octane and have no problems. Runs strong and clean with an average of 20mpg in the city.
