Product Highlights View Full Description

Engineered for high-demand applications, including trailer towing, heavy hauling, 4X4 off-road driving, commercial use and racing. Protects gears and bearings from scoring and wear. Excellent cold-flow properties. Outperforms all conventional gear oils. Recommended for all types of 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.

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-140) provides superior performance and replaces competitors' 75W-140, 80W-140 and 85W-140 gear oils. Use where these viscosities are required by OEMs and where maximum viscosity protection is needed for extreme severe-duty applications.

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.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS). USA and Canada (M)SDS are available upon request at 715-392-7101 or on the AMSOIL Website. Keep Out of Reach of Children. Don’t pollute.

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!!!!!!

Great gear oil.

By 

from MI

Verified Buyer

Comments about Severe Gear 75W-110:

Installed in my awd ptu on a 2012 Taurus sho. 75w140 is recommended but the severe gear 75w140 holds up well for my 30k mile change interval and I don't worry about it thickening. This ptu is in a very high heat zone near the catalytic converters and it beats up the lube, turning it to paste in about 50kmiles. Now with catless down pipes (40°f+ lower ptu temps) I don't need 75w140. The 75w110 severe gear is working great, and I notice less drive train drag than with the 75w140.

Excellent product that eliminated driveline 'clunking'

By 

from San Jose,CA

Verified Buyer

Comments about Severe Gear 75W-90:

Replaced OEM front and rear differential fluids of a new 2017 AWD Subaru Outback, and refilled with this 75W-90 product at approximately 3000 miles. With OEM fluids, an infrequent driveline 'clunk' used to occur when making tight (e.g., U-) turns. This behavior has NOT occurred (in over 2500 miles) since after refilling with Amsoil's synthetic Severe Gear differential oil.

For our vehicle, changing out the differential fluid shortly after 'breaking-in' the differentials seemed to be a good choice (judging by the drain plug magnet debris). I obviously can't comment about product longevity, but with the elimination of an infrequent driveline 'clunk', we're extremely pleased thus far!

Replaced diff fluid in rear of 13 f150 at 45000 Factory fluid was nasty and very dirty. Jury is out on this fluid but at 72000 now without issues....make sure you check to see if you have a limitex slip diff as you will need the additive.
