Purpose and Specifications

MOTUL CLASSIC 2100 15W50 is a semi-synthetic engine oil designed for classic cars and bikes built after 1970 with naturally aspirated, supercharged, or turbocharged 4-stroke gasoline and diesel engines. This modern update to the original 1966 formula delivers reliable protection with high zinc levels (over 1800 ppm ZDDP) and molybdenum additives that shield engine parts from wear during cold starts and high-heat operation up to 230°C.

The 15W50 viscosity flows easily in cold weather down to -20°C for quick startup protection, while staying thick at high temperatures to maintain steady oil pressure. Its synthetic base resists oxidation for consistent performance, meeting API SH/CF standards. Comes in a durable 2-liter iron can perfect for vintage engine maintenance.

When to Use / Replace?

Use this oil in stock classic engines from the 1970s-1990s to prevent wear, reduce sludge buildup, and ensure smooth operation. Ideal for carbureted or injected engines driven regularly or occasionally. Not recommended for modern post-1996 engines due to its high ZDDP formula.

• Replace every 5,000-8,000 km or annually, whichever comes first, to keep your engine clean and protected.
• Drain at least once a year and adjust based on your driving habits - more frequent for high-heat or dusty conditions.
• Shelf life: 3-5 years unopened in cool, dry storage.
