SEVERE GEAR® Synthetic 80W-90 Gear Lube
A multi-functional lubricant designed to surpass the requirements of equipment and automotive applications calling for an SAE 80W-90 viscosity grade. Formulated with wax-free synthetic base oils and high-quality additives, AMSOIL 80W-90 Synthetic Gear Lube resists thermal breakdown. Its naturally high viscosity index and shear-stable construction improve film strength and viscosity retention. Provides outstanding protection for gears and bearings, resists heat and helps extend equipment life.

AMSOIL Severe Gear® Synthetic Extreme Pressure (EP) Gear Lube is a premium-grade gear oil specifically engineered for maximum performance in severe-duty applications. This state-of-the-art AMSOIL formulation features an exclusive blend of high-viscosity, shear-stable synthetic base oils and an extra treatment of high-performance additives. AMSOIL Severe Gear Synthetic EP Gear Lube maintains its 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 helps 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 Gear Lube inhibits rapid lubricant degradation and component damage. Equipment runs better and lasts longer with AMSOIL Severe Gear Synthetic EP Gear Lube.
Performance
AMSOIL Severe Gear provides performance beyond that possible with conventional gear oil. This AMSOIL custom product offers superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life.
Temperature Extremes
AMSOIL Severe Gear EP Gear Lube excels in hot and cold temperature extremes. By design, it resists breakdown from high heat, preventing acids and carbon/varnish formation. Its wax-free construction also improves cold-flow properties, improving fuel economy and cold-weather shifting.
Ultimate Cold-Weather Protection
Some gear lubes fail to meet basic low-temperature requirements. Mobil 1 75W-140 Gear Oil, for example, failed to meet the requirements of the industry standards, AMSOIL SEVERE GEAR®, on the other hand, delivers 20% more cold-temperature protection than the standard requires. It delivers better cold-temperature protection than Mobil 1 and Valvoline SynPower.
Applications
AMSOIL Severe Gear Synthetic EP Gear Lube 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 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 motor homes.
Performance Features
- Advanced protection against wear, even with up to 15 percent water contamination1
- Controls Thermal Runaway
- Protects against rust and corrosion
- Helps reduce operating temperatures
- Maximum efficiency
- Flexible easy-pack for clean, fast installation
For product service life in differentials, consult your owner’s manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.
1 Based upon AMSOIL testing of AMSOIL Synthetic SEVERE GEAR® 75W-90 and Long-Life 75W-90 Synthetic Gear Lube in ASTM 3233 and ASTM D892.
2 Based upon results of samples of Mobil 1 75W-140 and Valvoline SynPower 75W-140 purchased in 2018 and tested in ASTM D2983 by an independent testing facility in May 2018. Samples sent blind to eliminate bias.

Severe Service
|
| Cars, SUVs, Light 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 three years, whichever comes first. | |
| Vocational/Delivery | Follow the OEM drain interval (miles or hours) for synthetic oil up to 120,000 miles 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 differentials, consult your owner’s manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.
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 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 (80W-90) provides superior performance and replaces competitors’ 80W-90 gear oils. It is formulated to exceed the requirements of front and rear differentials, transfer cases, transaxles, manual transmissions, oil-lubricated wheel bearings and steering gear boxes.
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®.
