I have lived in the US for 15 years but notice that Ford seems to run the cleanest? If you pull up next to a ford the inside of the exhaust burns nice and gray CLEAN( meaning it spends all its fuel) in Europe you see the the same, however most GM & Chrysler are all sooty and appear to run rich with big black sooty deposits in the tail pipe, including my last 3 SRT10's
