Smokey Exhaust

[shredder667]

hey guys, is it normal to be constantly developing this dark dusty crap on the back of the car on the exhaust side? just noticed every time i clean it, that the exhaust is leaving a noticeable amount of dark patches on the car.

Get your o2 sensor checked and your tune. It sounds like it is running too rich. Excess unburnt fuel. Seems to be common on a lot of turbo cars. Safer to be running a bit rich than too lean and detonating.

what fuel do you use?

i've heard of people using shell for example and getting the black soot all over their bumper, but not with bp.
