Pro Plus+ 10w40 Syntheti c 1 Liter

MAXIMA RACING OILS Pro Plus+ 10W40 Synthetic 1 Liter motor oil is engineered for high-performance engines that demand superior lubrication under extreme operating conditions. This full synthetic formulation provides advanced protection in applications ranging from street-driven performance vehicles to motorsport competition, where thermal stability and engine cleanliness directly impact reliability and longevity.

The 10W40 viscosity grade delivers consistent film strength across a wide temperature spectrum. The "10W" winter rating ensures rapid cold-start flow in low-temperature conditions, while the "40" hot rating maintains viscosity stability when engine temperatures climb during sustained operation or loaded driving. The synthetic base stock resists viscosity shear better than conventional oils, meaning the lubricant maintains its protective properties over extended drain intervals. Synthetic formulations also minimize deposit formation on piston rings and valve stems—critical for keeping high-revving engines clean and responsive.

This 1-liter bottle format suits top-offs between scheduled oil changes, as well as initial fill or reserve stock for vehicle owners who perform their own maintenance. MAXIMA's racing-focused oil chemistry is favored by enthusiasts and technicians working with modified engines, turbocharged systems, and high-displacement platforms where conventional mineral oils fall short. The Pro Plus+ line balances film strength with anti-wear additives designed to protect critical bearing surfaces and valve train components under the stress of aggressive throttle inputs and sustained high RPM.

Synthetic 10W40 oils are standard in the motorsport and performance aftermarket segment. This viscosity is compatible with a broad range of four-cycle gasoline engines—street cars, race platforms, vintage restorations, and utility vehicles with high-output powerplants. Always verify your engine manufacturer's recommended oil specification before use to ensure proper protection and warranty compliance.
