No kiddin. I could be completely off base with that last statement, but I don't think so. We'd be seeing a LOT of cases where rings weren't seating and we don't. I know plenty of people who use nothing but synthetic from break in and after. We just don't see the problem.

I worked for Cadillac for 10 years and in 2003 we had a piston recall on the northstar and GM said do not hone the cyls, new pistons, rings, rod bearings & gaskets test drive it and it is done, not 1 was a oil burner all the cyls had all the crosshatch even at 100,000 miles and they used mobil 5000 oil only the Cadillac XLR got synthetic because it had adjustable cam timing.
