Motul Classic SAE 50 is an ideal lubricant for both engines and gearboxes manufactured between 1900 and 1950. This mineral monograde lubricant features an exceptionally low detergent level, ensuring seamless compatibility with paper, felt, and fabric gaskets. The minimal detergent content effectively prevents the removal of soot and deposits within the lubrication system. This versatile option can also serve as a break-in oil, especially when shorter drain intervals are employed. It guarantees full compatibility with nonferrous metals like brass, bronze, and copper. Enhanced adhesion further facilitates easier starting, even after prolonged periods of inactivity.
