Synthetic oil during engine break-in? Here's what the oil manufacturers say...
I've heard it said that one should not use synthetic oil during break-in, because it can impair proper wear-in of the rings and other moving parts.
Well, my daughter (lucky gal) just bought a new 2007 Pontiac Solstice, and lo and behold, the car comes equipped with synthetic oil from the factory. Corvettes, Vipers, and many others do too!

So, this must mean that, at least for some new engines, that it's perfectly OK to run synthetic oils from day one. Does this apply to motorcycle engines? Hard to say. I assume that it depends on the manufacturing methods used, but these days, I assume most all automotive engines (including motorcycles, of course) use similar methods and are manufactured to close tolerances and require less rigorous break-ins than did engines made when I was a wee lad. So, the answer is: perhaps.
Enough of my uninformed rambling! What do the oil manufacturers say?
