10w40 Synthetic Oil Case 12x1 Quart RS1040

The 10W40 Synthetic Oil Case from MAXIMA RACING OILS is designed for automotive enthusiasts and mechanics seeking professional-grade lubrication for street and track vehicles. This case contains 12 quarts of oil, packaged as 12 individual 1-quart bottles, making it convenient for both maintenance and performance applications.

Engineered with advanced hydrocarbon technology, this synthetic formulation maintains film strength at high temperatures while ensuring smooth flow during cold starts. The 10-weight winter rating allows for quick circulation when temperatures are low, while the 40-weight summer rating ensures viscosity is sustained under load, preventing breakdown during high-RPM operation.

This oil is suitable for most naturally aspirated and moderately forced-induction engines that require a heavier synthetic oil than standard 5W30 offerings. Engine builders, performance shops, and serious DIY mechanics can trust MAXIMA RACING OILS to provide the necessary protection and performance for their modified vehicles.
