Product Description
AMSOIL SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricants are premium grade gear oils specifically engineered for maximum performance in severe duty applications. These state-of-the-art AMSOIL formulations feature an exclusive blend of high viscosity, shear stable synthetic base oils and an extra treatment of high-performance additives. AMSOIL SEVERE GEAR Synthetic EP Lubricants maintain their viscosity for long-lasting protection against metal-to-metal contact.
The proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against friction, wear, pitting and scoring.
AMSOIL SEVERE GEAR lubricants help prevent thermal runaway. A phenomenon caused by a lubricants inability to control friction and increased heat under high-stress conditions. By controlling thermal runaway, AMSOIL SEVERE GEAR® Synthetic EP Lubricants inhibit rapid lubricant degradation and component damage. Equipment runs better and lasts longer with AMSOIL SEVERE GEAR Synthetic EP Lubricants.
Performance
AMSOIL SEVERE GEAR ® provides performance beyond that possible with conventional gear oil. These AMSOIL custom products offer superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life.
Temperature Extremes
AMSOIL SEVERE GEAR® EP lubricants excel in hot and cold temperature extremes. By design, they resist breakdown from high heat, preventing acids and carbon/varnish formation. Their waxfree construction also improves cold flow properties, improving fuel economy and cold weather shifting.
Applications
AMSOIL SEVERE GEAR ® Synthetic EP Lubricants are excellent for severe applications, such as racing, towing, hauling, steep hill driving, commercial use, off-road use, rapid acceleration, frequent stop-and-go operation and high ambient temperatures.
For product service life in differentials, consult your owners manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.

Follow the OEM drain interval (miles or hours) for synthetic oil up to
250,000 miles or 3 years, whichever comes first. Otherwise, drain at twice the OEM interval for conventional oil.
|
|
Heavy Duty Off-Road Vehicles
|
Follow the OEM drain interval (miles or hours) for synthetic oil up to
120,000 miles or 1 year, whichever comes first. Otherwise, drain at twice the OEM interval for conventional oil.

For product service life in non-differential applications, consult owners manual or the OEM for either normal or severe synthetic oil service intervals. Where service intervals are unavailable, drain at twice the interval for conventional oil.
Gear oils should be changed more frequently when operating vehicles or equipment in dusty or dirty conditions unless the gear system is properly sealed and equipped with membrane type breathers.
Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check and service the gear oil frequently when water contamination is possible.
Use in differentials, manual transmissions or other gear applications where one or more of the following standards are specified:
API GL5 & MT1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037) for 250,000 miles, Mack GOJ, Arvin / Meritor 0-76M (75W-140), plus hypoid gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler. Can also be used in axles where API Service GL4 lubricant is recommended.
AMSOIL SEVERE GEAR (75W-40) replaces 75W-140, 80W-140 and and 85W-140 viscosity grades.
AMSOIL SEVERE GEAR (75W-90) replaces competitors 75W-90 and 80W-90.
AMSOIL SEVERE GEAR is compatible with conventional and synthetic gear oils. Mixing AMSOIL gear oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives, other than those specified by AMSOIL, are not recommended for use with AMSOIL gear oils. Package sizes include:
