Re: GM dexos oil. High mileage engine question
Dexos 1 (Properly rated, not "recommended") is darned good
oil. It's not for every car obviously, because other cars
don't need what Dexos 1 was designed for, and they do need
what Dexos 1 wasn't designed for. Your engine wants Dexos 1.
It's that easy. ![]()
