How long after an engine rebuild should I wait before using synthetic motor oil? I've got moly rings, and I remember reading that they take longer to seat than normal rings.
Also, what weight is best to run? A heavier oil increases oil pressure, but a lighter oil is said to reach critical enginer parts faster on startup. I'm considering trying the 0W30 Mobil 1. My car will see occasional street use to/from work during the summer (5 mile trip) and some strip action.
