Performance Plus Gear Oil

Performance Plus Gear Oil: Engineered for Severe-Duty Protection

When your drivetrain is under load — whether that's hauling a heavy trailer, navigating off-road terrain, or pushing a vehicle to its limits — the gear oil inside your differential and manual transmission is the last line of defense against metal-on-metal wear. Performance Plus has built its reputation on lubricants that stand up to exactly those conditions, and their gear oil lineup is a prime example of that philosophy in action.

A Foundation Built on Superior Base Oils

Performance Plus offers both conventional and full synthetic gear oils , giving drivers and fleet managers the flexibility to match the right product to their specific application. What sets these formulations apart starts at the molecular level: Performance Plus gear oils are designed with superior Group II+ base oils and high-quality additives, engineered to perform under severe operating and high pressure conditions.

Performance Plus automotive and industrial lubricants are the result of more than 30 years of research, technology, and investment. That depth of development experience translates directly into gear oils that go beyond meeting minimum standards — Performance Plus conventional and full synthetic gear oils meet and often exceed the specifications for use in the most stringent OEMs, including Caterpillar, Komatsu, Hitachi, Jeep, Mack, and many others.

Conventional and Full Synthetic Options

Performance Plus Conventional Gear Oils are premium quality multi-purpose gear oils formulated to perform in harsh operating conditions and to protect all vehicle and heavy-duty equipment differentials, final drives, manual transmissions, and gearboxes. For applications requiring an extra level of protection, the full synthetic line steps up the performance envelope considerably.

The Performance Plus Full Synthetic 75W-90 Gear Oil is extremely versatile and is designed for all differentials, including those equipped with slip or lock-up mechanisms. Formulated using superior base oils and high-quality additives, it performs across the widest operating temperature ranges for automotive, light, medium, and heavy-duty trucks, as well as farm, logging, and construction equipment — delivering exceptional resistance to gear wear and spalling.

For high-torque, high-load applications such as performance differentials and towing setups, the full synthetic option is designed for all differentials, including those with slip or lock-up mechanisms, covering farm and logging equipment as well as light, medium, and heavy-duty trucks. The 75W-140 Full Synthetic variant addresses the most demanding axle environments, where a thicker film is critical at operating temperature.

Broad-Spectrum Application Coverage

One of the practical strengths of Performance Plus gear oils is their wide compatibility. Compatibility with your vehicle's specifications is vital — always select oils that meet or exceed OEM requirements. Synthetic gear oils offer enhanced performance and longer service intervals, which can reduce maintenance costs. Ensuring the oil has the appropriate viscosity grade for your specific application affects film strength and the overall protection of the gears.

Whether in U.S. military combat vehicles or in race car engines on tracks from Daytona Motor Speedway to the Bonneville Salt Flats, Performance Plus lubricants perform in the toughest conditions. The comprehensive range meets or exceeds all North American standards for engine protection (API, ILSAC, and SAE) and is formulated to stand up against the toughest OEM requirements.

Whether you're a weekend enthusiast maintaining your vehicle's rear axle or a fleet operator keeping heavy equipment running smoothly, Performance Plus gear oil delivers the protection and versatility that demanding applications require.
