High Performance Gear Oils

Today’s Gears and Differentials and Their Applications Are More Demanding Than Ever Before

Whether it’s carrying more freight or moving more dirt, drivelines in both on- and off-road trucks today are experiencing more severe loading. This is complicated by more powerful engines, higher operating temperatures, and extended service intervals. To prevent the severe wear that can result, hypoid gears and differentials need advanced gear oil technology.
No Other Gear Oils Are More Advanced Than MAG 1 High Performance Gear Oils
MAG 1 High Performance Gear Oils are specially formulated with only the finest quality, hydrotreated, high viscosity index, paraffinic
base oils and the most advanced and rigorously-tested additive system to deliver protection and performance that can’t be beat. Nothing protects
better in the following critical performance areas:
• Exceptional protection against spalling and other wear, especially
under extreme heat, pressure and torque operation, ensures long
equipment life.
• Maintains viscosity, even under extreme operating temperatures,
resulting in longer fluid life and reduced operating costs.
• Prevents acid formation for superior protection against rust and
corrosion.
• Extra resistance to thermal degradation provides superior protection
against oxidation and deposit formation and significantly prolongs
seal life.
• Reduced foaming ensures smooth, efficient operation and proper
lubrication.
• Highly reliable performance over a wide range of temperatures.
MAG 1 High Performance Gear Oils Exceed All Warranty Requirements
MAG 1 High Performance Gear Oils are recommended for multi-purpose, extreme pressure applications including conventional differentials, gear boxes, limited slip rear axles manual transmissions and hypoid gears in two- and four-wheel drive tractors, combines and other farm equipment, as well as four-wheel drive off-road vehicles and construction equipment. They exceed warranty requirements for all equipment
calling for a gear oil that meet the following specifications:
API GL-5, MT-1 • Mack GO-J or earlier • MIL-L-2105E or earlier
