50WT Race Oil 1 Qt. (15W50)

The REDLINE OIL 50WT Race Oil 1 Qt. (15W50) is a premium synthetic motor oil engineered for high-performance racing engines and vehicles operating under extreme thermal and mechanical stress. Designed for enthusiasts and professional racers who demand superior protection during sustained high-RPM operation, this 15W50 viscosity grade delivers consistent film strength across wide temperature ranges while maintaining optimal engine cleanliness. The 1-quart bottle size offers convenient single-use or top-off quantities for track days, competition builds, and performance street applications.

This synthetic formulation features high zinc content, a critical additive package that provides enhanced anti-wear protection for flat-tappet and solid-lifter camshafts commonly found in race engines where conventional oils fall short. The 15W cold-pour viscosity ensures reliable cold starts and rapid oil circulation in winter conditions, while the 50-weight hot viscosity maintains robust film strength at elevated operating temperatures typical of turbocharged, supercharged, or naturally aspirated competition powerplants. Redline's proprietary synthetic base stock resists oxidation and thermal breakdown, extending drain intervals and safeguarding against sludge formation—critical for engines pushed to their limits on the dyno or circuit.

Professional racers, high-performance builders, and vintage muscle car restoration experts rely on this formulation for engines with modified valve trains, increased boost levels, or aggressive ignition timing where standard off-the-shelf oils cannot guarantee sufficient anti-wear chemistry. Ideal for both naturally aspirated and forced-induction platforms, the 50WT Race Oil is equally suited to circle-track competitors, drag racers, and road course enthusiasts who require consistent lubrication under sustained lateral and longitudinal G-forces. Check your engine manufacturer's specifications and consult technical data sheets to confirm compatibility with your particular application before use.
