So much conflicting information on this. Even Continental (the manufacturer of my new engine) is noticeably vague about the process. They give instructions for the first two hours of flight, suggest the first oil change at 10 hours, and say the break-in should be completed in the first 25 hours. I have 10 hours on the engine and completed the oil change. Oil consumption is very low and my mechanic is pushing to change over to ashless dispersant oil. I'd appreciate some comments from those of you "in the know". Change to regular oil, or stick with mineral oil for another 10 hours?
