Gear Master Gold
Full synthetic – 75W-90 gear oil
Gear-Master Gold 75W-90 gear oil is a full synthetic multi-purpose extreme pressure GL-5 gear oil designed to provide optimum performance in upper Midwest cold temperature climates. This formula provides outstanding shear resistance, oxidation and thermal stability to minimize sludge and varnish buildup when used in extended drain applications. Gear-Master Gold 75W-90 has excellent load carrying capacity that reduces wear along with rust and corrosion.
Features & benefits
- Fuel economy: Provides improved fuel economy and performance compared to conventional gear lubes such as 80W-90
- All weather protection: Outstanding oil pumpability at cold temperatures for quicker lubrication and less gear resistance while maintaining a heavy lubrication film at high operating temperatures
- Oil durability: Improved wear and oxidation resistance in extended drain service resulting in longer oil and equipment life
- Lower operating costs: Drain intervals under OEM programs leads to more driving time, less down time for repairs and oil changes allowing better equipment utilization and profits
- Outstanding protection: Shields against low-speed/high torque wear and high speed scoring
For maximum performance and compatibility, do not mix mineral and synthetic gear lubricants.
