GEAR PRO
Powerex GEAR PRO 80W-90 GL-4 is a multi-grade gear transmission oil formulated for manual gearboxes, transmission systems and selected axle applications where 80W-90 GL-4 type gear lubricant is recommended. The oil is designed to provide balanced extreme-pressure performance while supporting smooth gear interaction during regular service.
Built with PRO MESH LUBE TECH, GEAR PRO supports stable gear lubrication, gear surface protection and shift comfort in compatible manual transmission systems. Its 80W-90 GL-4 performance level is suitable for gearboxes requiring moderate EP protection and controlled lubrication behaviour without the aggressive EP chemistry normally associated with GL-5 hypoid axle oils.
GEAR PRO is suitable for workshops, vehicle owners and service centres looking for a dependable 80W-90 GL-4 gear transmission oil for compatible manual transmissions, utility vehicles, light commercial vehicles and gearbox applications where this grade is specified by the vehicle manufacturer.
- Suitable for manual transmission systems requiring 80W-90 GL-4 gear oil.
- Suitable for synchromesh manual gearboxes and gear transmission systems where GL-4 performance level is recommended by the vehicle manufacturer.
- Can be used in selected passenger cars, utility vehicles and light commercial vehicles where 80W-90 GL-4 gear lubricant is specified.
- Designed for gearboxes requiring balanced EP action, smoother gear shifts and stable lubrication under mixed operating conditions.
- Suitable for selected axle and gear applications only where GL-4 gear oil is specifically recommended.
- Not intended for hypoid differentials or axle systems requiring GL-5 gear oil unless 80W-90 GL-4 is specifically approved by the vehicle manufacturer.
