Protork Motor Oil & Lubricants


75W/90 Gear Oils

This is a fully-synthetic and heavy-duty type gear oil with high performance and a very long interval of oil change. It is used safely in the synchromesh and sliding-mesh gearboxes and differentials and transmission axles of modern passenger cars, commercial and terrain vehicles and heavy equipment, which run under heavy conditions. 

It protects the gear system against wear in all temperatures wih its efficient oil film. It preserves its fluidity under cold weather conditions and enables easy shift. It is highly resistant against oxidation in high temperatures and heat. 

It enhances the system efficiency by preventing corrosion, sludges, rust and foams. It delivers high lubrication performance and extends the intervals of oil change with its high viscosity index.
