Motul Classic Oil SAE 50 4-Stroke Mineral Engine & Gearbox Oil

This oil supports 4-stroke engines and gearboxes made between 1900 and 1950. You use it to protect internal components, aided by its 2-litre mineral monograde SAE 50 formulation with a very low-detergent content, reinforced adhesion, and compatibility with non-ferrous metals.Explore the key features of this oil:Mineral Monograde SAE 50 Base Oil: Uses a straight-grade mineral formulation that maintains stable viscosity under running temperatures, helping you keep consistent lubrication and reduce wear across engine and gearbox components.Very Low-Detergent Additive Level: Uses a controlled detergent content that leaves paper, felt, and fabric gaskets undisturbed, helping you avoid seal damage while limiting soot and deposit movement to maintain oil circuit cleanliness.Non-Ferrous Metal Compatibility: Formulated for use with brass, bronze, and copper components, allowing you to protect historic engines without chemical attack, helping you safeguard parts that rely on softer alloys.Reinforced Adhesion: Designed to improve oil cling on metal surfaces during downtime, aiding smooth start-up after long periods without use and helping reduce wear during first rotation.Break-In Suitability: Can be used for engine run-in when you shorten drain intervals, helping you seat new components and stabilise operation early in the service life.You use this 2-litre container to service and maintain lubrication in older engines and gearboxes where gasket materials and softer metal parts require compatible chemistry. It supports the way you care for heritage machinery, helping you handle cold starts after periods off the road. It can be a practical addition to your workshop when you maintain or recommission early-generation engines.
