PRODUCT DESCRIPTION
The mineral oil Gazpromneft GL-4 80W-90 is designed for use in mechanical gearboxes of passenger cars, trucks and offroad equipment. The oil provide high protection of work surfaces of gears and synchronizers from mechanical destruction and wear across a wide range of loads and speeds.

ADVANTAGES

• Excellent anti-wear properties - Protects the synchronizers and gears from wear. Retains the serviceability of the manual transmission.
• Viscosity stability - Maintains the required oil capacity throughout the change interval. Ensures reliable lubrication and stable operation of the manual transmission.
• Significant resistance to oxidation - Reduces the formation of deposits on gears and synchronizers and ensures smoothness when shifting between gears.
• High anti-corrosion properties - Prevents corrosion of synchronizers caused by acids. Increases the periods between major repairs.
• Low propensity to foam - Provides excellent lubrication and equipment reliability.

APPLYING

• In cars, road equipment (commercial trucks, buses, etc.), off-road equipment (mining, agricultural, etc.) of European, American, Asian manufacturers.
• In mechanical gearboxes of cars, including those manufactured by PAO "AVTOVAZ".
• In mechanical gearboxes and transfer cases in commercial transport, where API GL-4 service level is required.
• Do not use on bridges with hypoid gears.
