20w50 Petroleum Oil Case 4x1 Gallon

The 20W50 Petroleum Oil Case 4x1 Gallon from MAXIMA RACING OILS is a conventional motor oil formulation engineered for high-performance engines that demand robust protection under extreme operating conditions. This four-gallon case provides cost-effective supply for enthusiasts, fleet operators, and service professionals who rely on consistent viscosity and thermal stability. The 20W50 grade delivers reliable cold-start flow while maintaining film strength at elevated temperatures, making it ideal for naturally aspirated and lightly turbocharged engines operating in varied climates.

MAXIMA's conventional 20W50 formulation balances mineral-base oil technology with proven anti-wear additives to protect critical engine components during sustained high-RPM operation. The 20-weight winter rating ensures adequate viscosity at cold startup, reducing bearing stress during initial engine cranking, while the 50-weight hot rating maintains a protective oil film when cylinder temperatures reach operating peaks. This dual-viscosity approach suits engines where thinner winter oils risk inadequate protection and heavier mono-grades compromise cold-weather startability. The four individual one-gallon bottles in this case allow flexible inventory management and easy pouring without bulk handling.

This case format benefits racing shops, fleet maintenance departments, and serious enthusiasts who perform regular oil changes on multiple vehicles or high-mileage engines. The 32.5-pound case is designed for compact storage in shop cabinets or vehicle compartments while maintaining separation and safety. Verify your engine manufacturer's viscosity recommendations before use, as 20W50 is typically specified for larger-displacement engines, vintage vehicles, or applications where heavier oil protection is engineered into the fuel system and cooling design. Store in a cool, dry location away from direct sunlight to preserve additive performance over time.
