GL-4 75W-90, 80W-90, 85W-90, 85W-140 vehicle gear oil series products
Short Description:
Product Overview: This product is blended using advanced technology with synthetic base oils, high-quality hydrotreated base oils, and compatible compound additives.
Performance Characteristics:
* Excellent anti-wear properties and load-bearing capacity; forms a stable extreme pressure lubricating film, reducing noise and gear wear, ensuring gearbox transmission efficiency;
* Good oxidation resistance; prevents viscosity increase and reduces deposit formation;
* Good shear stability; maintains its viscosity grade even after prolonged use;
* Good rust and corrosion prevention; reduces rust formation and prevents corrosion of non-ferrous metals.
Applications: Suitable for lubrication of drive shafts (axles) in light and medium-load vehicles and gears in some manual transmission vehicles.
