SAE 30 Break-In Oil Case 3 x 5 Quart Bottle

The Lucas Oil SAE 30 Break-In Oil Case with 3 x 5 Quart Bottles is specifically designed for newly rebuilt or freshly overhauled engines that require precise lubrication during the critical break-in period. This formulation is essential for mechanics and enthusiasts performing engine rebuilds, bore jobs, or complete top-end overhauls, as the initial miles are crucial for long-term engine durability.

Break-in oil serves a different purpose than standard operating oil; it is formulated to facilitate controlled ring seating and piston ring bedding while protecting freshly machined cylinder walls and bearing surfaces from premature wear. The SAE 30 viscosity grade provides optimal film strength at engine startup temperatures while ensuring sufficient flow to reach critical bearing surfaces before full oil pressure develops. Additionally, Lucas Oil's break-in formulation includes anti-wear additives (ZDDP) that are crucial for older engines with flat-tappet camshafts and lifters.

This product is ideal for those working on rebuilt engines, vintage builds, or any application requiring enhanced protection during the break-in phase. The case contains three 5-quart bottles, providing ample volume for a complete engine flush and fill after the break-in period, along with extra capacity for top-offs during the critical run-in phase.
