GEAR-90
Powerex GEAR-90 EP-90 GL-4 is a manual transmission gear oil formulated for gearboxes and selected gear assemblies requiring moderate extreme-pressure performance. The oil is designed to support smooth gear engagement, stable lubrication film and reliable gear surface separation during regular service.
Built with GEAR SHIELD EP TECH, GEAR-90 supports balanced EP behaviour, gear surface protection and consistent lubrication between mating gear components. Its EP-90 GL-4 performance level makes it suitable for manual transmission and compatible gear systems where GL-4 gear oil is recommended by the vehicle or equipment manufacturer.
GEAR-90 is suitable for workshops, vehicle owners and service centres looking for a dependable EP-90 GL-4 manual transmission gear oil for compatible gearboxes, selected axle assemblies and gear applications requiring moderate EP protection.
