PRODUCT DESCRIPTION
Gazpromneft GL-5 80W-90 is mineral transmission oil intended for use in transmission units subjected to high loads (main transmission, drive axles), where the API GL-5 performance level is required. This oil effectively protect the parts of hypoid gears from wear and tear.

ADVANTAGES

• High anti-scratching properties - Constantly lubricates the teeth of the gears at different gearbox loads. Maintains the service life of the transmission elements.
• Oil resistance to mechanical deconstruction - Maintains optimal viscosity value throughout the oil change interval. Reduces vibration and noise in bridges during operation.
• Corrosion protection - Forms a protective layer on the surface of metals. Increases mileage to major repairs.
• Significant resistance to oxidation - Forms fewer acids that adversely affect gasket materials. Reduces maintenance costs.
• Resistance to thermal decomposition - Reduces deposits that impair heat dissipation during transmission operation. Avoid overheating bridges.

APPLYING

• For cars, road equipment (trucks, buses, etc.) and off-road equipment (mining and agricultural equipment, etc.) of European, American and Asian manufacturers.
• Drive axles for road trucks, including MAN, MB and Scania.
• Drive axles for off-road equipment.
• Onboard gearboxes, transfer cases and power take-off boxes.
• Unsynchronized mechanical gearboxes or those with steel synchronizers.
