ASTROL GEAR OIL 90

Alef Grup Astrol Gear Oil 90

The smooth and quiet operation of a vehicle depends not only on the engine but also on the health of its transmission, differential, and drivetrain components. Since these systems are exposed to high pressure, metal-to-metal contact, and heavy loads, the durability of the lubricant used is critically important. Astrol Gear Oil 90 is a high-performance, mineral-based gear oil specifically developed for manual transmissions and differentials. With strong wear protection, high heat resistance, and a long service life, it provides safe and reliable operation for vehicle owners.

What Is Astrol Gear Oil 90?

Gear Oil 90 is a monograde gear oil. The “90” refers to the oil’s viscosity at high temperatures, indicating a thick and durable lubricant capable of maintaining protection even under heavy loads. Oils of this type are especially preferred for:

• Heavy-duty operating conditions

• High torque transmission

• Gear reducers and differentials carrying substantial loads

Alef Grup Astrol Gear Oil 90 is formulated to meet these demanding requirements.

Key Features of Astrol Gear Oil 90

Enhanced Protection with Extreme Pressure (EP) Additives

Gears within transmissions and differentials remain in constant contact, increasing the risk of wear over time. Thanks to its EP additive technology, Astrol Gear Oil 90 protects metal surfaces even under heavy loads and helps prevent surface fatigue such as gear pitting.

High Thermal Stability

Transmission oils are exposed to elevated temperatures during prolonged use. The oil’s strong oxidation resistance helps prevent thickening, foaming, and sludge formation. As a result:

• Stability is maintained as temperatures rise

• The lubrication film remains intact

• Internal system cleanliness is supported

Reduced Friction Between Gears

Its viscous structure forms a durable oil film between gears, reducing friction and delivering:

• Quieter operation

• Less vibration

• Reduced power loss

Long Service Life

Although mineral-based, its high-quality additives provide extended operational life, helping lower maintenance costs.

Effective Protection Against Corrosion and Rust

Metal surfaces can deteriorate when exposed to moisture and chemical residues. Astrol Gear Oil 90 contains anti-corrosion additives that:

• Help prevent rust

• Protect metal surfaces from chemical damage

Recommended Applications

Due to its high viscosity, Astrol Gear Oil 90 is particularly suitable for:

Manual Transmissions – Supports smoother gear shifts and reduces wear on gear surfaces.

Differential Systems – Protects gears operating under heavy loads.

Heavy-Duty Drivetrain Components – Ideal for trucks, tractors, buses, and construction machinery requiring high torque transfer.

Industrial Gearboxes and Reducers – Provides long-lasting protection in industrial machinery.

Benefits for Users

• Extended transmission and differential lifespan

• Quieter and more balanced operation

• Strong resistance to wear

• Lower maintenance costs

• Stable performance under high temperatures and heavy loads

• Longer oil change intervals

• Easy application with broad system compatibility

Having passed Alef Grup’s quality control processes, this product meets user expectations for reliability.

Technical Advantages

Oil Change Interval

The replacement period for Astrol Gear Oil 90 varies depending on operating conditions but is typically:

• 20,000 – 40,000 km for standard use

• Shorter intervals for heavy-duty vehicles

• According to manufacturer guidelines in industrial applications

Although transmission and differential oils are changed less frequently than engine oils, regular inspection remains essential.

Conclusion: Strong Structure, Reliable Performance

Alef Grup Astrol Gear Oil 90 is a high-quality gear oil developed for transmission and differential systems operating under demanding conditions. With its pressure-resistant formula, oxidation stability, and anti-wear additives, it can be safely used in both passenger and commercial vehicles for years of dependable service.
