5w30 Synthetic Oil Case 4x1 Gallon RS530

The 5W30 Synthetic Oil Case 4x1 Gallon RS530 by Maxima Racing Oils is engineered for drivers and mechanics who demand superior engine protection and performance across a wide range of operating temperatures. Whether you're running a high-performance street car, daily driver, or modified engine build, this full synthetic formula provides the reliability and consistency that modern powerplants require. Bulk case packaging makes it the practical choice for shops, fleet operators, and serious enthusiasts who service their own vehicles regularly.

Maxima's synthetic 5W30 viscosity grade delivers rapid cold-start flow at 5-weight while maintaining 30-weight protection at operating temperature, a critical balance for fuel efficiency and engine longevity. The synthetic base stock resists oxidation and thermal breakdown better than conventional mineral oil, extending drain intervals and reducing sludge buildup in critical bearing surfaces and valve trains. RS530 formulation includes anti-wear additives that protect against ring wear and cam lobe scuffing, particularly valuable in turbocharged, supercharged, or high-compression builds where conventional lubricants fall short.

This case of four 1-gallon jugs is ideal for those performing regular maintenance on multiple vehicles or maintaining a well-stocked service bay. The 5W30 grade meets automotive industry specifications and is compatible with gasoline engines in passenger cars, light trucks, and performance vehicles that call for this viscosity. With 32.73 pounds total weight across compact 11.95 x 10.2 x 18.1-inch dimensions, the case stores easily and ships efficiently, making bulk purchases economical for both DIY mechanics and professional technicians.
