This is a fully synthetic gearbox oil specially developed using superior additives for use in manual gearboxes of buses, trucks, semi-trucks, construction machinery, passenger cars and small commercial vehicles. It minimizes operating temperatures in the gearboxes it works in, eliminating pitting and surface deterioration problems that can occur in gears due to high temperatures. Thus, it minimizes maintenance costs and creates longer oil change intervals. Thanks to its special formulation, it provides maximum lubricity and an excellent film layer even at low temperatures, ensuring quiet operation and fuel economy. Thanks to the high-tech anti-wear additives in its formulation, it provides superior protection against wear in main gears and gear bearings from the first moment of operation.
