Product Highlights View Full Description

Formulated for the severe operating conditions of today’s pick-up trucks, SUVs, heavy equipment and other hard-working vehicles.

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.

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.

  • Rust and Corrosion Protection
  • Helps Reduce Operating Temperatures
  • Maximum Efficiency
  • Long Oil, Seal & Equipment Life

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 TrucksDrain at 100,000 miles of service or according to the owner's manual, whichever is longerDrain at 50,000 miles of service or according to the owner's manual, whichever is longer
Heavy Duty Class 8 Line HaulFollow the OEM drain interval (miles or hours) for synthetic oil up to 250,000 miles or three years, whichever comes first.
Vocational/DeliveryFollow the OEM drain interval (miles or hours) for synthetic oil up to 120,000 miles or three years, whichever comes first.
Heavy Duty Off-RoadFollow 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.

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-90) provides superior performance and replaces competitors' 75W-90 and 80W-90 gear oils. It delivers the best fuel efficiency and cold-temperature performance of the Severe Gear oils.

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. If limited-slip differential chatter occurs, add AMSOIL Slip Lock® friction modifier additive.

got another 70000 miles out of it .I was sold been using it in every vehicle sence. When you do all your own service work yourself you notice where n tear on internal parts, and i've got to say the products from amsoil When you rely on your truck to make a living and cant afford break downs. You only put the best product in it. I've used other products in the past. but one slipping transmission and switched to amsoil products. Well offer the best protection i've come across "greasy" Hands Down Matt.S.

Gear Oil

Amsoil does not control friction modifier, so if you have a limited slip diff don't use the gear oil alone!!!!!!

30k Miles and Like New

By 

from California and Ohio

Verified Buyer

Comments about Severe Gear 75W-90:

Used this in transfer case and diffs of a 2013 FJ Cruiser for 30k miles. Vehicle is daily driver and upgraded and abused off road. Stock fluid after 30k was dark and separated in appearance. After 30k with AMSOil Severe Gear, the front diff AMSOil fluid looked almost new with significantly reduced metal shavings. The rear looked only lightly used with once again significantly fewer metal shavings. I highly recommend this fluid!
