Performance
AMSOIL SEVERE GEAR provides performance far beyond what is possible with conventional gear oil. We design our gear lubes to provide superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life.
Temperature Extremes
AMSOIL SEVERE GEAR excels in hot and cold temperature extremes. By design, it resists breakdown from high heat, preventing acid and carbon/varnish formation. Its wax-free construction also improves cold-flow properties, improving fuel economy and cold-weather shifting.
Applications
AMSOIL SEVERE GEAR is 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 pickups, 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 motor homes.

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 Service | Severe Service | |
| Cars, SUVs, Light Trucks | Drain at 100,000 miles
(161,000 kilometers) of service or according to the owner’s manual, whichever is longer |
Drain at 50,000 miles
(80,500 kilometers) 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 (402,500 kilometers) or three years, whichever comes first. | |
| Vocational/ Delivery | Follow the OEM drain interval (miles or hours) for synthetic oil up to 120,000 miles (193,200 kilometers) or three years, whichever comes first. | |
| Heavy-Duty Off-Road | Follow the OEM drain interval (miles or hours) for synthetic
oil up to 100,000 miles or two years, whichever comes first. |
|
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.
AMSOIL SEVERE GEAR 75W-90, 80W-90, 75W-110 and 75W-140
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 other GL-5 based specifications from vehicle manufacturers, including Ford,* GM* and Chrysler.* Can also be used in axles where an API GL-4 lubricant is recommended.
AMSOIL SEVERE GEAR 75W-85
Use in differentials, manual transmissions and other gear applications requiring any of the following specifications:
API GL-5/MT-1, MIL-PRF 2105E, SAE J2360, Ford XY-75W85- QL, GM 19300457, 19418501, 92184900, 19369842, Ram 68210057AB, 68083381AA, 68364258AA, 68232947AB,
68378949AA, 05136035AC, Toyota Genuine Gear Oil LT, 08885-02506
AMSOIL SEVERE GEAR is compatible with conventional and synthetic gear oils. Mixing AMSOIL gear oil 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 oil.
AMSOIL SEVERE GEAR is compatible with most limited-slip differentials. For applications that require additional limited-slip friction modifier, add AMSOIL Slip Lock.®
