Synthetic 10w30 Oil Case/6

Lucas Oil Synthetic 10W30 Oil Case/6 is engineered for drivers and mechanics who demand reliable engine protection across diverse climates and driving conditions. This full synthetic formula addresses the challenge of maintaining optimal viscosity in both cold starts and sustained high-temperature operation—critical for modern engines running tighter tolerances and extended drain intervals. Whether you're maintaining a daily commuter, a modified performance build, or fleet vehicles, this case of six quarts provides the baseline protection required for consistent engine health and longevity.

The 10W30 viscosity grade delivers excellent low-temperature fluidity (10-weight pumpability in winter conditions) while maintaining a stable 30-weight film strength at operating temperature. Lucas Oil's full synthetic technology resists viscosity shear, meaning the oil maintains its protective thickness under sustained acceleration, prolonged idling, and turbocharged boost cycles—conditions where conventional oil degrades rapidly. The formulation includes anti-wear additives and detergents that combat sludge and varnish buildup, reducing carbon deposits that compromise ring sealing and fuel economy on both naturally aspirated and forced-induction engines.

This case format suits both professional technicians and serious hobbyists who service multiple vehicles or maintain equipment year-round. The 10W30 rating is compatible with most gasoline engines manufactured from the 1980s onward, including turbocharged four-cylinder platforms, naturally aspirated V6/V8 engines, and light-duty diesel applications—always verify your owner's manual or service specification before installation. For users running extended oil change intervals or operating in variable climates, the synthetic formulation's stability and resistance to thermal breakdown provide measurable protection compared to conventional mineral oil.
