Industrial Lubricants and Gear Oils

Evolutionary Performance™

OEMs continue to evolve driveline designs and operating conditions are becoming more severe.  Today’s gear lubricants require excellent load-carrying capability where extreme pressures and shock loading are expected. One brand has evolved right alongside today’s equipment – MAG 1®. Only the most advanced driveline gear oils meet the difficult challenges of effectively balancing performance, strength and durability.

Outstanding Protection

MAG 1® Driveline Gear Oils are engineered for use in drivetrains that require gear lubricants with excellent load-carrying capability and where extreme pressures and shock loading are expected. Our Full Synthetic Gear Oils are designed to provide demanding extended drain performance. These gear oils deliver excellent performance:

• Protect against thermal degradation.

• Reduce oxidation.

• Reduce wear and corrosion.

• Provide improved shear stability.

These gear oils can be used for on-highway passenger cars, SUVs, light- and heavy-duty trucks, buses, and vans. Other applications include off-highway industries, such as construction, mining, quarrying and agriculture. Plus, we have a Marine Gear Oil.

Important: these oils are not recommended for applications requiring API GL-4 level performance. They are not intended for automatic, manual or semiautomatic transmissions for which engine oil or automatic transmission fluids are recommended.

Please refer to the owner’s handbook or our Lube Advisor for the OEM application requirements for your vehicle or equipment.

Powerful Anti-Friction, Anti-Wear Chemistry

MAG 1® provides outstanding control of friction and wear. Advanced molecules bond together to create a wear-resistant shield that works to build barriers that reduce friction and wear.

Withstands the Most Extreme Conditions

MAG 1® Gear Oils provide unsurpassed protection even in the harshest conditions of hot and cold climates, pressure, power density, micropitting or oxidation, shrinking sump sizes or separation of air and water.

MAG 1 Driveline Gear Oils are specially engineered and formulated to provide:


Excellent protection for load, shear and shock.


Outstanding wear and corrosion protection.


Thermal stability and long life for gear, bearings and seals.
