Product Details

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 orsevere synthetic oil service intervals. Where service intervalsare unavailable, drain at twice the interval for conventionaloil.

Gear oils should be changed more frequently when operatingvehicles or equipment in dusty or dirty conditionsunless the gear system is properly sealed and equippedwith membrane type breathers.

Note: AMSOIL does not support extended drain intervalswhere water contamination occurs. Check and service thegear 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® (80W-90) provides superior performance and replaces competitors' 80W-90 gear oils. It is formulated to exceed the requirements of front and rear differentials, transfer cases, transaxles, manual transmissions, oil-lubricated wheel bearings and steering gear boxes.

AMSOIL SEVERE GEAR® is compatible with conventionaland synthetic gear oils. Mixing AMSOIL gear oils with otheroils, however, will shorten the oil life expectancy and reducethe performance benefits. AMSOIL does not supportextended drain intervals where oils have been mixed.Aftermarket oil additives, other than those specified byAMSOIL, are not recommended for use with AMSOIL gearoils.

AMSOIL SEVERE GEAR® is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.

Gear shops think highly of this oil

I''m going to start towing a camper several times a year and wanted a quality gear oil in the diff and new transmission fluid. After much research I decided on Amsoil and have piece of mind that it will protect just fine.

BMW R1150 GS Motorcycle

I have been using the Synthetic 80W-90W Gear Lube in the Transmission and Final Drive unit of my 2001 BMW R1150GS motorcycle or years. It never breaks down between changes even though I ride in 1st and 2nd gear for hours on Utah desert roads for hours at a time. shifting is always silky smooth. I highly recommend Amsoil Synthetic Gear Lube wherever the motorcycle specs call for Gear Lube. If your Transmission also houses a "wet clutch" be sure to research the correct Amsoil product to use with a "wet clutch" as there is a special requirement to insure that "wet clutches" won't slip.

We go on two week trips every year on which we average about 5,000 miles and I have had not problems :-)

Excellent product.

This gear lube doesn't ball up like tar in the cold weather. Better protection and mobility. Great in all diffs, especially with all wheel drive vehicles these days.
