The Motul SAE 20W-50 (5L) is a high-quality mineral-based or semi-synthetic engine oil designed for older generation gasoline and diesel engines, especially those manufactured between the 1950s and 1980s. With its high viscosity rating, it provides a thick and stable oil film, making it particularly suitable for engines that operate under high temperatures or are prone to oil consumption. The 20W rating ensures acceptable cold-start protection, while the 50-weight at high temperatures delivers robust lubrication and wear resistance for older engines with larger tolerances.

This oil is ideal for classic vehicles, motorcycles, and high-mileage engines that require extra cushioning and thermal stability. It features a reinforced additive package that includes anti-wear agents, detergents, and dispersants to help protect engine internals, reduce sludge buildup, and maintain cleanliness. Motul SAE 20W-50 is especially beneficial for flat-tappet cam engines or vehicles that have not transitioned to modern synthetic oil specifications. Its 5-liter packaging offers a practical and economical solution for those maintaining or restoring older engines with confidence and care.
