Purpose and Specifications

Valvoline VR1 Racing 20W-50 is America's #1 racing oil, engineered since 1965 for high-performance pushrod and flat-tappet engines in classic muscle cars, hot rods, and race cars. This premium conventional 1L bottle delivers extreme wear protection with high zinc and phosphorus levels that shield pistons, cams, and bearings under high RPMs and heavy loads.

It flows smoothly at cold starts down to -20°C and stays thick up to 150°C for reliable lubrication during track days or spirited street driving. Special friction modifiers boost horsepower by reducing heat, while enhanced anti-foam agents and thermal stability prevent breakdown in extreme conditions. Meets ACEA A3/B3, API SL specs and works with gasoline or partial alcohol fuels.

• High zinc formula: 2X more for superior film strength on critical parts
• Anti-foam protection: Guards engine during high-speed stress
• Cleaner operation: Resists high-temp deposits for longer engine life

When to Use / Replace?

Use Valvoline VR1 20W-50 in older high-compression engines without catalytic converters or wet clutches. Perfect for flat-tappet cams needing extra zinc to avoid wear. Ideal for operating temps from -20°C to 150°C in racing, drag strips, or hot street performance.

Replace every 5,000 km or 6 months for street use, or after every race/event for track cars to maintain peak protection. Shelf life is 5 years unopened in cool, dry storage.

FAQ

Is this oil safe for my classic car with flat-tappet cam?
