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 wear, pitting and scoring. AMSOIL SEVERE
GEAR® lubricants help prevent “thermal runaway” — a phenomenon
caused by a lubricant’s 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
towing, hauling, steep hill driving, commercial use,
plowing, racing, off-road use, rapid acceleration,
frequent stop-and-go operation and high ambient
temperatures.
Higher horsepower, towing and hauling capabilities of modern vehicles make turbo diesel pick-ups, SUVs, vans and delivery/utility vehicles especially prone to severe service. Other severe duty vehicles include light, medium and heavy-duty trucks, buses, heavy equipment, 4X4s, tow trucks, race cars, tractors, and motorhomes.
For product service life in differentials, consult your owner’s manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.
| . | NORMAL |
SEVERE |
| Cars, SUV, Light & Medium Duty Trucks | Drain at 100,000 miles of service or according to the owner’s manual, whichever is longer | Drain at 50,000 miles of service or according to the owner’s manual, whichever is longer |
| Heavy Duty Class 8 Line Haul | 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 Vocational | 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 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.
Recommended for use in differentials, manual transmissions and other gear applications requiring any of the following specifications: API GL-5, MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037), Mack GO-J, or the differential (hypoid) gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler. Can also be used in axles where an API GL-4 lubricant is recommended.
AMSOIL SEVERE GEAR® (75W-110) provides superior performance and replaces competitors’ 75W-110, 75W- 90 and 80W-90 gear oils. It delivers better viscosity protection than SEVERE GEAR 75W-90 and better fuel efficiency than SEVERE GEAR 75W-140.
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.
