XP5 20w50 Semi-Synthetic Case 12 x 1 Quart

The XP5 20w50 Semi-Synthetic Case 12 x 1 Quart from DRIVEN RACING OIL is engineered for high-performance engines that demand superior protection under extreme heat and load conditions. This multi-grade formulation addresses the needs of street-driven performance vehicles, drag racing builds, and modified engines running elevated boost levels or sustained high RPMs. Semi-synthetic blends bridge the gap between conventional and full synthetic oils, offering enhanced oxidation resistance and thermal stability while maintaining cost efficiency for enthusiasts building serious power.

The 20w50 viscosity grade delivers robust film strength across cold starts and sustained operation, critical when cylinder pressures spike during forced induction or nitrous oxide systems. DRIVEN's formulation includes anti-wear additives that reduce boundary friction on cam lobes and valve lifters—a priority in flat-tappet or solid-roller camshaft engines where conventional oils fall short. The semi-synthetic base resists shear thinning better than mineral oil alone, maintaining viscosity integrity through extended drain intervals typical of performance builds. This chemistry also minimizes sludge buildup, a recurring problem in modified engines that see aggressive tuning and storage between driving seasons.

The 12-quart case format suits shops, fleet operators, and serious home builders who service multiple vehicles or perform frequent oil changes on high-mileage builds. Engine builders and tuners routinely spec XP5 20w50 for freshly assembled blocks, supercharged small-blocks, and naturally aspirated platforms running premium fuels and aggressive timing curves. Compatibility spans vintage muscle cars, modern LS engines, and custom fabrications; always verify your owner's manual or builder documentation before use. Store in a cool, dry location to maintain additive stability, and follow your engine builder's recommended service intervals—typically 3,000 to 5,000 miles for race or heavily modified engines.
