A special modifier increases the oil viscosity index, which prevents oil from entering the combustion chamber, which in turn reduces soot formation and eliminates exhaust gas smoke.
Anti-wear components minimize wear on engines with any mileage and extend their service life.
Improves the stability and strength of the oil film on the rubbing parts of the engine, which facilitates cold start and reduces starting wear.
Especially effective in severe operating conditions and when oil is diluted with fuel.
Suitable for petrol and diesel engines and all types of engine oils (synthetic, mineral, etc.)
