Break in oil ?

Use Joe Gibbs Driven break-in oil BR30 (5W30) or BR (15W50).

It's pretty pricey stuff but worth every penny considering all the work you have put into the engine.

My machinest uses Joe Gibbs. I'm not really a brand name guy but i'd advise buying a dedicated break in oil. DOn't pretend to be a chemist and buy a gimmick oil additive.
