Is there any truth to the notion that cars should be running petroleum oil during the break in period before switching to synthetic?
A premium synthetic motor oil can be used during break-in without any trouble. In fact, dozens of vehicle models come factory-filled with synthetic oil now. Rebuilt engines may still require break in oils that don’t prevent wear as well and will allow rings to seat, but not factory supplied engines.
