Purpose and Specifications

MOTUL CLASSIC 20W50 is a premium mineral engine oil crafted for classic cars and bikes from the 1950s to 1970s. This 20W50 viscosity oil flows smoothly at cold starts down to 0°C and stays thick up to 150°C, protecting big-displacement engines in hot rods, muscle cars, and vintage racers during city, road, or highway driving.

Packed with high zinc (ZDDP over 1800 ppm) and molybdenum additives, it shields flat-tappet cams and high-lift valvetrains from wear, cuts friction for better power, and fights rust during long storage. Its anti-wear formula extends engine life in high-mileage classics, controls oil burn, and is safe for old cork or paper gaskets. Meets API SF/CC standards with modern motorsport tech for all-season use.

When to Use / Replace?

Use in naturally aspirated or turbo gasoline/diesel engines from 1950-1970. Perfect for warmer climates or wide-tolerance engines needing thick hot protection. Replace every 5,000-8,000 km or 6-12 months, or sooner if driving hard like track days. Shelf life is 5 years unopened; store cool and dry.

Key Benefits:

• Boosts engine longevity with superior wear protection at high temps
• Quick cold starts prevent startup wear, even after winter storage
• Reduces oil consumption in leaky old engines
• Extra rust shield for lay-up periods

FAQ

Is MOTUL CLASSIC 20W50 good for air-cooled engines? Yes, its thick hot viscosity and zinc additives protect air-cooled classics like Porsches at high temps up to 150°C, though check your manual for exact fit.

How often should I change it? Every 5,000-8,000 km or 6 months for daily drivers; more frequent for racing to maintain peak protection.

Does it work in modern cars? No, designed for 1950-1970 classics; modern engines need newer API specs.
