Why Rymax Gevitro GL-5 80W-90
Extreme Pressure Protection
Advanced EP additives provide superb protection against metal-to-metal contact under severe hypoid gear loading including shock loads.
Improved Cold Flow vs 85W-140
80W-90 grade offers better low-temperature fluidity than the heavier 85W-140 — recommended where improved cold-start performance is required.
Corrosion & Oxidation Resistance
Additives prevent corrosion, oxidation and foam formation — maintaining oil integrity across the full service interval.
Thermal Stability
Consistent viscosity and film protection under sustained axle operating temperatures in heavily loaded rear drives.
Broad Vehicle Coverage
Suitable for hypoid gears, hub reduction units and differentials across passenger cars, buses and commercial vehicles.
Anti-Wear Performance
Proven wear protection for hypoid gear tooth surfaces and differential bearings.
Recommended Applications
