Severe Gear 75W-90 High Performance Gear Lube
AMSOIL’s Severe Gear is always making headlines. This time it’s been the product which attracted Banks Performance Diesel..
If you want a lubricant which significantly improves the power to the wheels but more importantly adding protection which you can measure in temperature and fuel economy – this is it!
Formulated for the severe operating conditions of today’s pick-up trucks, SUVs, heavy equipment and other hard-working vehicles.
Astonishing Performance under the most Demanding Conditions
AMSOIL Severe Gear® 75W-90 Synthetic Extreme Pressure (EP) Gear Lube is a premium-grade gear oil (GL5) 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 of the 75W-90
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. Expect significant reductions of heat and even gained mileage. We’ve even had customers driving large RV or trucks with heavy trailers on mountain inclines report 4 to 7 more miles per hour after switching to the Severe Gear product. It remains one of the most advanced products in the entire AMSOIL line.
Basically ends meteal to metal contact under high pressure loads.
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 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. And let’s not forget those with classic cars with little modification and or towing.

Normal Service
|
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 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.
Recommendations
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.

Reviews
The Differential Difference!
By DUSTIN, a Verified Buyer on January 16, 2023 ;
I put Severe Gear 75W-90 in my 2019 Charger ScatPack. I immediately noticed former gear transitions and no more rear end whine. Although I’ve used Amsoil for years, this is the first time using Severe Gear. I’ll buy again for sure!

By SCOTT, a Verified Buyer from Florida on January 14, 2023 ;
So far I feel better running this than Yamaha stander gear oil
Dodge Challenger Rear Diff
By AXEL, a Verified Buyer from South Carolina on January 06, 2023 ;
Purchased Amsoil Severe Gear Oil for my Dodge Challenger Redeye who’s rear diff was starting to whine when turning. After changing the oil the whine went away. Thanks Amsoil!
Severe Gear
By CHRIS, a Verified Buyer from Hopkins, MN on January 04, 2023 ;
I honestly can’t say whether Severe Gear is any better than the dozens of gear oils I’ve used over the years? But I do know I love the handy pouch it comes in! It made changing the differential oil in my family’s three Subarus very easy and mess-free. I’ll continue to use Severe Gear in all my vehicles going forward.
Second time around
By TAcker, a Verified Buyer from Chatham Ontario on October 13, 2022;
This is the second time using Amsoil gear oil. I have a 2012 GMC Sierra that I had changed the front and tear diff oils at 5,000 km. The truck now had 133,000 km and I put in fresh oil. I like the new flexible container; helps make it easier to get it in. Love these oils: truck runs smoother in my opinion after installing.
Takes the headache out of servicing your differential
By WILLIAM, a Verified Buyer from Atlanta, Georgia on October 17, 2022;
They really nailed the packaging on this one. It really lets you simply pour the fluid into the differential without getting pumps or scoops or any other steps in between.
