Product Description
AMSOIL Severe Gear Synthetic Extreme Pressure (EP)
Lubricants are premium grade lubricants 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 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.

For product service life in non-differential applications, consult owner's 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 GL-5 & MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037) for 250,000 miles, Mack GO-J, Arvin/Meritor 0-76N (75W-90), plus hypoid gear oil specifications from all foreign and domestic manufacturers such as GM, Ford and Daimler Chrysler. Can also be used in rear axles where API Service GL-4 lubricant is recommended.
AMSOIL SEVERE GEAR (75W-90) replaces competitors 75W-90 and 80W-90 viscosity grades.
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.
AMSOIL SEVERE GEAR is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock friction modifier additive.
