10w40 Synthetic Oil 1 Gallon RS1040

The 10W40 Synthetic Oil 1 Gallon RS1040 by MAXIMA RACING OILS is designed for drivers and mechanics seeking reliable engine protection in various temperature conditions. This synthetic oil formulation is ideal for both cold starts and high-performance driving, ensuring optimal viscosity for a range of driving scenarios.

With a 10W40 viscosity rating, this oil provides the thin-film protection of a 10-weight oil during cold conditions while maintaining the load-carrying strength of a full 40-weight at operating temperatures. Its advanced synthetic base stock and additive package offer superior shear stability compared to conventional oils, ensuring consistent viscosity even under high-stress conditions.

This oil is particularly beneficial for street-driven performance vehicles, daily drivers, and modified engines that experience mixed duty cycles. Its anti-wear properties protect critical engine components, while detergents help keep the engine clean, making it a valuable choice for those who frequently push their engines to the limit.
