Product 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.

Product Description
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.

Advantages in Using AMSOIL's Easy Pack

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.

Performance Features
• Advanced protection against wear, even with up to 15 percent water contamination 1
• 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.

SERVICE INTERVAL

.
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 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 (75W-110) provides superior performance and replaces competitors' 75W-110, 80W-110 and 85W-110 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 oils 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 oils.

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).

Great

Ive been running this in both axles for 112,000 miles. I dont have issues with kicking it in 4WD in extreme cold (no 4WD button/knob in this rig). The rear locking Eaton differential works reliably with zero noise. I tow consistently and I tap shift 97% of the time I drive to avoid using my service brakes which puts extreme stress on my drivetrain (bought truck new, truck has 125K hard miles, original factory installed rotors & pads are still on it and only the pads have worn by 2mm max). I drain & fill the diffs every 45K and I only get metal dust at the plugs, no flakes. So, I would say its working well.

This oil cured that instantly and now its nice and quiet. Despite this oil being thicker than factory i have not seen any negative difference in fuel economy.

I will purchase again

I abuse this truck. High torque, towing (7k), and spirited driving are the norm. The gearbox doesn't chatter, used L/S additive, and is very quiet.

Impressed

Used for a a 2015 Ram 1500. The old oil came out at 77 k miles. It was foaming extremely bad (air bubbles in oil). I replaced with severe gear and Amsoil's limited slip fluid.

I noticed smoother driving characteristics with the severe gear. The truck rolls better. I also noticed a 1 mpg increase in fuel economy.

Great product.

I have 2013 freightliner Cascadia. Was changing oil in differentials. So far, best product market has to offer. Differentials runs much quieter, lower temperatures. And over all feels so smooth.

Smooth Operation

I had this gear oil installed in my 1994 Ford Ranger XLT 2WD differential by a local repair shop. An inspection of the gear set revealed all was well. This truck has well over 200,000 miles on it and this marked my second differential oil change. My decision to use the Amsoil 75W-90 Servere Gear oil was based on the fact this truck hauls a wide variety of cargo (from rocks, wood to motorcycles) and I treasure reliability. After driving this truck for 23+ years, I've become familiar with it's sounds and feel and I noticed an absence of a slight howl coming the back of the truck at freeway speeds. No other changes or adjustments were made during the oil change and I maintain my own tire pressures. I look forward to not having to be concerned about this for another 100,000 miles!

Awesome products that work

I've been using Amsoil for over 30 years from everything 2 stroke, and every kind of racing engine you could think of. Also transmissions rear drive axels and also my everyday daily drivers. The proof is no failure and awesome reports from pro builders that rebuild my stuff.

Love Amsoil fluids

I have replaced all my OEM fluids with amsoil and my Jeep is much nicer to drive. Shifting (manual transmission and transfer case) is smoother, differential whine is gone.

Gears are quieter and runs cooler I run this in my daily drivers and my old cars example 670 hp Cuda that I road race, I do have to add the limited slip additive for it not to chatter

Great gear oil.

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.

A must have for trucks that work!

Simply the best hands down. My trucks tow heavy in the most extreme heat conditions, this can be torture on gears. I typically run my trucks to about 500k then replace them. To date I have never had a single issue in the rear end at all, other than the occasional pinion seal. Do yourself a favor and step up to real protection.

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.

Replace that "Universal" oil out of your H-D trans NOW!

I use AMSOIL Severe Gear 75W-110 in the 6-speed transmission of my 2009 H-D Road King. The SYN-3 oil installed at the factory made the transmission noisy and hard to find neutral when it was warmed up. Since I starting using AMSOIL Severe Gear 75W-110 over 24,500+ miles ago, my transmission has stayed much quieter, shifts without "clunking" and finding neutral is still a breeze.

Waited for this new SAE spec 75W-110

This is at the upper end of a 75W-90 gear oil - right in line with the old 75W-90 rating, as modern 75W-90 synthetics are usually too thin.
Quieted down a moody 1981 Dana 44, and required a minimal amount of friction modifier for a rear Chrysler 9-1/4".
