A Vehicle Gear Oil additive package is a combination of additives designed to improve the performance and protect the gears of a vehicle.
These packages usually include anti-oxidants, rust and corrosion inhibitors, extreme pressure additives, viscosity improvers, and foam suppressants.
These products are specifically designed to keep the gears of a vehicle working as they should and to protect them from wear and environmental damage.
Some packages also contain detergents and dispersants to keep the oil clean and free of contaminants.

This product is a additive package for vehicle gear oil, composed of high-quality extreme pressure anti-wear agents, rust inhibitors, corrosion inhibitors, and other functional additives,After reasonable compounding and strict testing and evaluation, this additive package has excellent extreme pressure and wear resistance, oxidation stability, and rust and corrosion resistance.
Vehicle Gear Oil additive packages is formulated with a 3.5% dosage and suitable base oil to prepare heavy-duty vehicle gear oil, meeting the requirements of API GL-5 and GB 13895 standards.
It also has good oxidation stability, extreme pressure and wear resistance, corrosion resistance and rust resistance.
It can meet the requirements of low speed and high torque,high speed impact load,various harsh use conditions such as humid and hot environments.
Vehicle gear oil is an essential component in a vehicle’s transmission system. It is responsible for lubricating the gears and bearings, reducing friction and wear, and protecting against corrosion and rust. An additive package can be added to the gear oil to further enhance its performance and provide additional benefits. Here are some common additives found in a gear oil additive package:
- Extreme Pressure (EP) Additives: These additives are designed to provide enhanced protection under high-pressure and high-temperature conditions. They form a sacrificial layer on the metal surfaces, reducing friction and wear between gears and preventing metal-to-metal contact.
- Anti-wear additives: These additives are formulated to reduce wear on gears and bearings, extending their lifespan. They create a protective film on metal surfaces, preventing direct contact and minimizing friction during operation.
- Antioxidant additives: Antioxidant additives help prevent oxidation and degradation of the gear oil. They inhibit the formation of harmful by-products that can lead to oil thickening, sludge formation, and corrosion.
- Rust and corrosion inhibitors: These additives protect metal surfaces from rust and corrosion caused by moisture and other contaminants. They create a protective barrier, preventing the formation of rust and extending the life of the gears and bearings.
- Friction modifiers: Friction modifiers reduce the friction between gear surfaces, improving efficiency and reducing energy loss. They help to minimize gear noise, vibration, and heat generation, resulting in smoother gear shifts and improved fuel economy.
- Viscosity modifiers: Viscosity modifiers are used to improve the stability of the gear oil’s viscosity across a wide range of operating temperatures. They help maintain proper lubrication and protection even in extreme temperature conditions.
- Foam inhibitors: Foam inhibitors reduce foam formation in the gear oil, helping to maintain consistent lubrication and preventing the formation of air pockets that can lead to gear wear and failure.
These additive packages are carefully formulated to balance the performance and protection requirements of gear oil. They enhance the gear oil’s properties, promote smoother gear shifts, reduce wear and maintenance costs, and extend the lifespan of the transmission system.
