SAE 20W50 Break-In Oil Case 3 X 5 Quart Bottle

The SAE 20W50 Break-In Oil Case 3 X 5 Quart Bottle from Lucas Oil is specifically designed to protect new engine builds and rebuilt powerplants during their crucial initial operating hours. This oil is ideal for those who have just completed an engine overhaul, installed new pistons and rings, or are breaking in a recently reconditioned short block.

This specialized break-in lubricant features a carefully formulated viscosity and additive package that meets the needs of fresh internal components. The 20W50 formulation combines a robust base stock with anti-scuff additives and elevated levels of zinc and phosphorus, which are essential for proper sealing and protection during the critical break-in phase.

Engine builders, performance shops, and automotive enthusiasts will find this three-bottle case provides ample capacity for multiple engine starts and warm-up cycles. The balanced viscosity profile ensures proper circulation during cold starts and maintains film strength at operating temperatures, reducing wear on tight-tolerance engine components.
