Gear Oil extra ep 80W-90 AND 85W-140 are high performance, multipurpose, thermally stable and heavy duty automotive gear lubricants. Gear Oil are blended from highly refined base stocks with high performance EP additive system for providing excellent load carrying capacity to protect gear equipment against surface distress (i.e. spalling, pitting, scoring and wear) under heavily loaded conditions. Special inhibitor system has also been incorporated to provide excellent oxidation stability to resist gear oil degradation and thickening during long periods of severe high temperature operations. High viscosity index and low pour point assure good film strength for gear oil protection at both high and low temperatures.
