Very efficient anti-deposit and anti-black sludge power which maintains a clean engine. Vehicle compatibility: old generation cars and taxis. Suitable for old technology engines running on petrol, alternate fuels and for motorcycles. The high performing anti-wear additive results in reduction of engine internal frictions and increases life and duration by wear reduction. The viscosity at high temperature (sae 20w-50) is perfectly adapted to gasoline engines which tend to be heavy on oil.
