5W20 Synthetic Blend 12 x 1 Quart

The 5W20 Synthetic Blend 12 x 1 Quart motor oil from Extreme Racing Oil delivers reliable engine protection for street performance applications and daily driving. This semi-synthetic formulation is engineered for drivers who demand both fuel efficiency and robust protection without the premium cost of full synthetic oil. The 12-quart case format ensures you have plenty of stock for regular maintenance intervals across multiple vehicles or extended storage.

Synthetic blend technology combines mineral and synthetic base stocks to provide superior viscosity stability across temperature ranges while maintaining the film strength necessary for engine protection. The 5W cold-flow rating ensures quick starts in cold climates, reducing engine wear during startup, while the 20-weight rating provides adequate protection during normal operating temperatures. This balanced viscosity profile reduces oil sludge buildup, extends drain intervals compared to conventional oils, and supports consistent performance in both highway and city driving conditions.

Owners of standard gasoline engines, daily drivers, and fleet operators benefit most from this street performance blend, particularly in moderate climates where extreme heat or cold is not a primary concern. The 1-quart bottles simplify storage, transport, and inventory management—ideal for shops, service facilities, and enthusiasts who maintain multiple vehicles. Verify compatibility with your engine's manufacturer specifications before use; most standard gasoline engines manufactured in the last two decades accept 5W20 oil without modification.
