As John said, yup, I'm an OM602/603 kinda guy. And when running well, the 60x do generate less soot. My departed OM617 generated noticeably more... roughly 1% per 3000 miles, but it varied a lot each time. And that was with the EGR disabled. (!)
Both my 603 engines have been pretty consistent at 1% per 10,000 miles with EGR disabled. My 602 had been approx 1% per 3000 with EGR, but I just killed the EGR, and I'm very curious what the next oil analysis looks like (gotta wait a while though... another 8kmi before it's due for a change.)
