Anti-frictional additive for motorcycle oil. The additive is colloid dispersion of a hard lubricant based on Molybdenum Disulphide (MoS2) in the mineral oil; the additive is fully compatible and mixable with all types of motor oils (mineral, semi-synthetic, synthetic); retains stability during long-term thermal and dynamic loads; reduces fuel and oil consumption; extends the engine service life. It is tested on turbocharged engines and catalysts. Application. The additive should be added based on the proportion 5% (50 ml for 1 liter of oil) in automotive engines, based on the proportion 2% (20ml for 1 liter of oil) in motorcycles with wet clutches. The additive mixes with the motor oil itself, almost immediately.
