XP5 20w50 Semi-Synthetic Case 12 x 1 Quart

The DRIVEN RACING OIL XP5 20w50 Semi-Synthetic Case is engineered for high-performance engines that demand robust lubrication under extreme heat and load. This 12-quart bulk case (twelve 1-quart bottles) is ideal for mechanics and enthusiasts who service multiple vehicles or maintain track cars, street rods, and modified engines that run hard and hot. The 20W50 viscosity grade bridges the gap between full synthetic and conventional oil, offering cost-effective protection without sacrificing performance—making it a trusted choice for vintage engines, hot rods, and street machines that prioritize reliability over cutting-edge formulation.

The semi-synthetic blend delivers superior film strength at high operating temperatures while maintaining pumpability in cooler conditions, thanks to its carefully selected base oil and additive package. The 20W rating ensures fast cold-start cranking, while the 50-weight body provides thick-film protection during sustained high-RPM operation—critical for engines with loose tolerances, flat-tappet cams, or extended drain intervals typical in modified powerplants. This formulation resists thermal breakdown and oxidation better than straight mineral oil, extending engine life in applications where conventional 50-weight motor oil would break down under continuous stress.

Mechanics and builders commonly specify the XP5 20w50 for naturally aspirated V8 engines, vintage truck restorations, and carbureted performance builds where older engine designs benefit from a heavier oil grade. The bulk 12-quart case format makes it economical for professional shops, race teams, and home builders who change oil frequently or service multiple vehicles. Compatibility spans most conventional and modified engine platforms; however, always verify your owner's manual or builder's specifications, as some modern turbocharged or high-compression engines may require lighter synthetic grades for optimal piston cooling and fuel economy.
