Royal Purple XPR 5W-50 Synthetic Racing Oil - 1 Quart Bottle
The leading synthetic motor oil engineered for the harshest racing conditions: Royal Purple XPR 5W-50. This high-performance formula stands out in oval track, drag racing, and marine applications by providing consistent lubrication under prolonged extreme pressure and heat far beyond what standard oils can handle. Racers choose it for reliable engine safeguarding, noticeable power increases, and longer component durability, ensuring your setup runs stronger lap after lap. When compared to other options, XPR 5W-50 consistently delivers better startup wear resistance and overall engine efficiency, positioning it as the smartest pick for anyone pushing high-revving motors to their limits.
Key Specifications and Features
- Viscosity Grade: SAE 5W-50 Flows easily at cold starts while maintaining thick-film strength at high temperatures up to 500°F+.
- Base Formula: Full synthetic with proprietary Synerlec® additive technology for reduced friction, lower operating temps, and cleaner internals.
- API Rating: Exceeds racing standards; not intended for street use due to high zinc/phosphorus levels (ZDDP) that protect flat-tappet cams and valvetrains.
- Performance Benefits:
- Stronger anti-wear film reduces metal-to-metal contact during aggressive shifts and boosts horsepower by 2-5% in dyno tests.
- Resists breakdown for extended drain intervals in competition environments.
- Compatible with methanol, nitro, and alcohol fuels without dilution issues.
- Direct switch from other synthetics no engine flush required.
Vehicle Fitment

- Drag Racing: Top Fuel dragsters, Funny Cars, Pro Stock vehicles (compatible with GM LS-series, Chrysler Hemi, Ford Coyote engines in 1980s-2025 chassis).
- Marine Racing: Offshore powerboats and inboard performance craft (e.g., Mercruiser V8s, Volvo Penta outboards from 1990s-current).
- General Compatibility: Any air- or water-cooled racing engine with capacities up to 8 quarts; ideal for vintage muscle cars (1965-1985 Chevy Camaro, Ford Mustang, Dodge Challenger) rebuilt for track use, or modern turbo/supercharged setups in Subaru WRX/STI (2002-2025) and Honda Civic Type R (2017-2025) race-prepped variants.
