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.

For product service life in differentials, consult your owner's manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.

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.

      Reduces gear whine!

      Comments about Severe Gear 75W-140:

      I've been having issues with my 3.73 gears, after taking my car to the track the gears whine and it can become annoying. Since I've been using Amsoil's 75W-140 for the diff, the gear whine has gone down a bit. The car feels great and my Torsen Limited Slip Diff seems to be behaving very well with the new oil. I recommend this product.

      Grear Gear Oil

      Comments about Severe Gear 75W-140:

      Run this in 3 trucks in both the front and rear diffs. One of those also runs it in the transfer case (NP205). Have had zero issues and have noticed less wear during yearly inspections. No fault of the gear oil at all but you need to make sure all your seals are in good working condition as this will let you know if it they are not, much more so then normal conventional gear lube, at least in my experience. Via an external temp reading (infared gun) of the diff cover after same trips with same load have noticed a drop in temperatures as well. Basically it works, and is the only thing I will run in high abuse applications.

      Amsoil 75w-140 synthetic gear oil.

      By 

      from East Texas

      Verified Buyer

      Comments about Severe Gear 75W-140:

      Use in a ford f150 as required. Change around every 60, 000 miles. May not be necessary, but can't hurt to have clean oil. Decided to use Amsoil after reading an independent test/study on gear lubes by a major oil company. Many oils were good. But Amsoil outperformed the other oils in nearly all of the tests performed. In 1998 when I first changed the oil Amsoil was all I could get in synthetic 75w-140. Ford dealers didn't carry it and the service manager recommended using 90w, stated, "We use 90w". I said, "the diff. Tag states 75w-140! You don't sell the oil you recommend?". Wonder how may diff's ford burned up? Have used Amsoil since then.

      Comments about Severe Gear 75W-90:

      I have used Amsoil products in my entire driveline of all of my vehicles and equipment for years. I run Severe Gear in the transfer case and both differentials of my truck, and the rear differential of my high horsepower car. The benefits are: smoother and quieter operation, especially in cold weather; 1-2 mpg increase; much better protection. I do not use extended drain intervals, but there is always that option. I'm picky about my vehicles, I use this for the protection, better operation, and peace of mind.

      Comments about Severe Gear 75W-90:

      My new F-150 only has 15k on it now and I still haven't changed the front axle but I did switch the rear over to 75-140 at 10k. Had a ford ranger that I bought new and switch it's rear to amsoil at about the same mileage. I used it for my lawn service runner. It was over loaded it's whole life up until 102,000 when I was hit and they totaled it. I sold that rearend to another guy that was going to rebuild it with a spool and deeper gears. He called me back and said it looked like brand new inside. Pretty amazing considering what that truck went through.
