30WT Race Oil 1 Qt. (10W30)

Redline Oil's 30WT Race Oil 10W30 synthetic motor oil is engineered for high-performance racing applications where engine protection under extreme conditions is non-negotiable. This 1-quart bottle delivers premium lubrication designed specifically for naturally aspirated engines running in competition, where sustained high RPM operation, elevated temperatures, and maximum power output demand superior film strength and thermal stability.

The 10W30 viscosity grade provides cold-start pumpability while maintaining robust protection at operating temperature. The high-zinc formulation—essential for race engines—supplies anti-wear compounds that protect cam lobes, lifters, and bearing surfaces during the intense shearing forces of competition driving. This synthetic base stock resists oxidation and thermal breakdown far longer than conventional mineral oils, extending drain intervals and maintaining viscosity consistency across temperature extremes. The formulation is optimized for engines without modern catalytic emissions systems, making it ideal for vintage race cars, dedicated track vehicles, and naturally aspirated race motors.

Racers running small-block V8s, inline engines, and naturally aspirated powerplants in club racing, vintage competition, and off-road motorsports rely on Redline's race-specific formulations to maintain engine durability lap after lap. The 30WT designation indicates this oil is tuned for engines that benefit from slightly heavier protection at temperature while maintaining proper flow characteristics—a critical balance in race applications where engine tolerances are often tighter and operating windows narrower than street engines. Each quart can be used individually or combined with additional quarts for complete oil changes on smaller-displacement race engines.
