VP 10w40 HI-Performance Racing 1 Qt - 32oz

The VP 10W40 Hi-Performance Racing motor oil is purpose-built for serious automotive enthusiasts and track-focused drivers who demand superior engine protection under extreme conditions. This 1-quart bottle delivers the robust lubrication characteristics needed for modified engines, high-RPM applications, and performance builds where standard mineral oils simply cannot keep pace. Whether you're running a street-strip hybrid, a weekend racer, or a heavily turbocharged daily driver, this racing-grade formulation ensures your engine stays protected when temperatures spike and loads intensify.

VP Racing's 10W40 blend combines a lightweight winter viscosity with robust high-temperature film strength, critical for engines that see sustained boost pressure or consistently elevated cylinder temperatures. The 10-weight cold-start rating enables faster oil circulation on startup, while the 40-weight hot rating maintains a protective boundary layer even as oil temperatures approach 250°F—well beyond what conventional passenger-car oils can handle. Advanced detergent and anti-shear chemistry prevents viscosity breakdown during sustained high-RPM running, protecting against bearing wear and ring blowby common in modified powerplants.

This formula suits engines with roller or flat-tappet cam profiles, supercharged mills, and naturally aspirated builds demanding extended drain intervals under stress. Racers running carbureted or fuel-injected engines benefit from superior oxidation stability and foam resistance, both essential for consistent performance across back-to-back heat cycles. The 32 oz. quart size makes it ideal for top-offs between services, oil system flushes, and keeping a supply on hand at the track or shop. Compatible with most competition engines and street-performance applications where synthetic or conventional racing oil specifications are called for.
