GWOST 8581-78

Motor oil M-10DM consists of mixtures of distillate and residual components produced from sulfur oils, and a new additive composition that improves the anti-corrosion and anti-wear properties of DM oils.

It is designed for winter and summer operation of high-pressure turbocharged diesel engines, working in severe conditions. M-10DM oil can be used in naturally aspirated diesel engines with significantly increased mileage between oil changes. Provides reliable lubrication of domestic and imported equipment (mining heavy trucks, industrial tractors with high power engines of water or air cooling, excavators, bulldozers, forklifts, pipelayers).
