15w50 Break-In Oil 1 Gallon

MAXIMA RACING OILS 15W50 Break-In Oil is specifically designed for new engine builds, fresh rebuilds, and the critical initial operating hours when proper lubrication is essential for long-term durability. This oil is ideal for mechanics and enthusiasts overseeing engine break-ins, whether for street builds or high-performance applications.

The formulation of this break-in oil includes elevated levels of zinc and phosphorus anti-wear additives (ZDDP) to enhance ring seating and prevent scuffing during the crucial run-in period. The 15W50 viscosity grade ensures optimal performance, providing a thin film at cold starts while maintaining robust protection at operating temperatures. Additionally, the oil contains detergents that help suspend combustion byproducts, preventing sludge buildup that could affect engine performance.

This oil is particularly beneficial during the initial startup and early operation of engines, making it suitable for both naturally aspirated and forced-induction engines. Users should apply this oil during the break-in phase, typically lasting 500 to 1,000 miles, before transitioning to a long-term cruising oil.
