HR6 10w40 Synthetic Oil Case 12 x 1 Quart

The HR6 10W40 Synthetic Oil Case (12 x 1 Quart) from Driven Racing Oil is purpose-built for high-performance automotive applications where engine protection and thermal stability demand premium lubrication. This full synthetic formulation is engineered for drivers and mechanics who push their vehicles beyond stock parameters—whether that means track days, towing under load, or extended street performance driving. A case of twelve quarts ensures you have adequate supply for regular maintenance intervals on modified engines or multi-vehicle shops.

Driven Racing Oil's 10W40 synthetic blend delivers superior film strength and oxidation resistance compared to conventional mineral oils, critical for turbo engines, supercharged builds, and high-rpm naturally aspirated platforms. The 10-weight cold-start viscosity ensures rapid oil circulation during cold startups, reducing dry-start wear on critical bearing surfaces, while the 40-weight high-temperature rating maintains a protective cushion under sustained load and heat. Full synthetic basestock chemistry resists viscosity breakdown and sludge formation, extending oil change intervals and keeping internal components cleaner—especially important in modified engines running tighter tolerances or aggressive boost levels.

This product suits street and competition mechanics maintaining late-model performance cars, LS-based engine swaps, small-block modifications, and any turbocharged or supercharged application where heat management and film strength matter. The 10W40 viscosity strikes a balance for both high-idle and cruise-rpm stability, making it versatile across bracket-racing, road-course, and daily-driven platforms. Case packaging (twelve individual 1-quart bottles) simplifies inventory management and top-offs between full service intervals, keeping your shop or garage stocked and organized.
