Why Rymax Gevitro GL-4 80W-90
GL-4 EP Protection
Formulated with EP additives appropriate for synchronised manual gearboxes — providing excellent gear protection without the aggressive sulphur chemistry of GL-5 that can attack yellow metal synchronisers.
Synchroniser Safe
Unlike GL-5, the Gevitro GL-4 formulation is compatible with brass and bronze synchroniser rings — essential for correct specification in most European manual gearboxes.
Corrosion & Oxidation Resistance
Additives prevent corrosion, oxidation and foam building — maintaining oil integrity across the full service interval.
Thermal Stability
Excellent thermal stability ensures consistent viscosity and gear protection under sustained operating temperatures.
Broad Vehicle Coverage
Suitable for manual gearboxes and final drives across passenger cars, buses and commercial vehicles.
Anti-Wear Performance
Proven wear protection for gear tooth surfaces, synchronisers and bearings.
Recommended Applications
Commercial Vehicle Gearboxes
Manual transmissions on trucks, buses and light commercial vehicles where API GL-4 is specified.
Passenger Car Manual Gearboxes
European and Asian passenger car manual transmissions where GL-4 is specified — particularly important for synchroniser protection.
Agricultural Tractors
Manual gearboxes and final drives on tractors where a GL-4 specification is required.
Light Commercial Vehicles
Van and bakkie manual gearboxes across the South African fleet.
Industrial Gearboxes
Light to medium industrial manual gearboxes where API GL-4 is specified.
Workshop Use
General workshop gear oil for manual transmissions where GL-4 80W-90 is the most common specification.
