15w50 Break-In Oil Case 12x1 Quart

The 15W50 Break-In Oil Case by MAXIMA RACING OILS is designed to provide premium engine protection during the critical initial operating hours of newly rebuilt or freshly machined engines. This case contains 12 individual 1-quart containers, making it ideal for high-performance enthusiasts and mechanics who require precise viscosity control for new pistons, rings, camshafts, and valve train components.

Break-in oil serves a distinct function by providing elevated film strength and anti-wear additives necessary to protect fresh metal surfaces under load. The MAXIMA 15W50 formulation balances cold-start flow with sustained high-temperature protection, ensuring adequate circulation during initial cold cranking and maintaining film strength as ring tension increases during the first 500–1000 miles of operation.

This case format is particularly beneficial for shops, race teams, and serious restorers managing multiple engine builds or performing controlled dyno break-ins. The advanced zinc and phosphorus anti-wear compounds protect nascent bearing surfaces and valve stems, making this oil compatible with catalytic converters while ensuring effective ring seating dynamics.
