Hello everyone, been reading the boards for a while and must admit I'm addicted. My question is simple, the old saying that you shouldn't use synthetic oil (What's synthetic? Right!) to break in a new motor. Is this a wives tale or truth? I Know more and more vehicle coming from the factory are filled with a synthetic, yet even here on this forum people seem to think it's wrong. I want to know everyones opinion on this. Voice your opinion and most importantly why you think the way you do! Great forum, well advised readers, enjoy.
