Product Details

Product Applications

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.

• High Load Gear and Bearing Protection
• Longer Oil and Equipment Life
• Lower Maintenance Costs
• Compatibility With Conventional and Synthetic Gear Lubes
• Multi-functional for Multiple Applications

Service Life

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.

Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check and service the gear oil frequently when water contamination is possible.

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.

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 (80W-90) is compatible with synthetic and conventional gear oils, however mixing oils reduces the benefits and nullifies the extended service life recommendations.

AMSOIL SEVERE GEAR (80W-90) 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.
