How do you prime an engine after rebuilding?
The engine should be primed with oil before starting. The oil should be of the same viscosity as the oil to be used in the engine.
How long is the break-in period for a rebuilt engine?
The break-in period for a rebuilt engine is the same as for a new engine.
How do you Prelube a new engine?
We recommend that you use a high quality engine oil such as Mobil 1, Castrol, or Valvoline.
