Valvoline VV975 75W-90 Full Synthetic Gear Oil 1 Qt

Product Description

The VALVOLINE OIL COMPANY VV975 is a full synthetic 75W-90 gear oil engineered for demanding drivetrain applications. Sold in a one-quart container, this SynPower formulation delivers thermally stable, extreme pressure lubrication capable of performing across a wide temperature range, from severe cold starts to sustained high-heat operation. The multi-viscosity 75W-90 rating ensures consistent film strength under both low-temperature startup stress and high-temperature load conditions. Drivetrain technicians and fleet service professionals install this lubricant during differential service intervals or whenever a manufacturer specification calls for a full synthetic 75W-90 gear oil.

The VV975 is specifically recommended for limited slip hypoid differentials, where conventional gear oils can cause chatter, wear, or inadequate protection under torque loading. It is also compatible with conventional gear lubricants, making it suitable for top-off applications or transitional service where a full flush is not performed. Typical use cases include passenger vehicle differentials, light truck rear axles, and similar drivetrain components requiring extreme pressure protection and thermal stability across seasonal temperature swings.

Key Features

• Full synthetic 75W-90 formulation for broad temperature range performance
• Thermally stable under sustained high-heat and extreme pressure conditions
• Specifically recommended for limited slip hypoid differentials
• Compatible with conventional gear lubricants for top-off flexibility
• Sold in a one-quart unit for single-differential service or precise volume control

Compatibility

Specifically recommended for limited slip hypoid differentials. Compatible with conventional gear lubricants. Consult the vehicle or equipment manufacturer service manual to confirm 75W-90 full synthetic gear oil is the correct specification before installation.

Installation Notes

Differential fluid service should be performed by a qualified drivetrain or automotive technician following the vehicle manufacturer service interval guidelines. Before draining and refilling, allow the axle to cool to a safe handling temperature and use appropriate fluid-rated drain and fill equipment. Do not overfill beyond the manufacturer-specified capacity, as excess fluid can cause aeration and seal damage. Dispose of used gear oil in accordance with local environmental regulations.
