100% high performance synthetic lubricant for 4-stroke engines and engine gearboxes (joint lubrication with engine) are subject to fierce regimes and competition. It meets the low viscosity requirements that allow a reduction in fuel consumption (“Fuel Economy”), while allowing an optimized friction for oil-washed joints avoiding slippage and premature wear. Provides extended and prolonged protection against wear and corrosion at high and low temperatures. It has excellent thermal stability, reduced evaporation loss, excellent lubrication and cutting durability.
