AMSOIL SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricants are premium grade gear oils specifically engineered for maximum performance in severe duty applications. These state-of-the-art AMSOIL formulations feature an exclusive blend of high viscosity, shear stable synthetic base oils and an extra treatment of high-performance additives.
Package sizes include:
1-Quart Bottles (case of 12)
AMSOIL SEVERE GEAR® Synthetic EP Lubricants are 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 motorhomes.
AMSOIL SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricants are premium grade gear oils specifically engineered for maximum performance in severe duty applications. These state-of-the-art AMSOIL formulations feature an exclusive blend of high viscosity, shear stable synthetic base oils and an extra treatment of high-performance additives. AMSOIL SEVERE GEAR® Synthetic EP Lubricants maintain their 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® lubricants help 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 Lubricants inhibit rapid lubricant degradation and component damage. Equipment runs better and lasts longer with AMSOIL SEVERE GEAR® Synthetic EP Lubricants.
AMSOIL SEVERE GEAR® provides performance beyond that possible with conventional gear oil. These AMSOIL custom products offer superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life.
* Superior Film Strength
* Controls Thermal Runaway
* Rust and Corrosion protection
* Reduced Operating Temperatures
* Improved Efficiency
* Longer Oil, Seal, & Equipment Life
AMSOIL SEVERE GEAR® EP lubricants excel in hot and cold temperature extremes. By design, they resist breakdown from high heat, preventing acids and carbon/varnish formation. Their waxfree construction also improves cold flow properties, improving fuel economy and cold weather shifting.
For product service life in differentials, consult yourowner’s manual or the Original Equipment Manufacturer(OEM) to establish the application, NORMAL or SEVERE.
|Cars, SUV, Light & Medium Duty Trucks||Drain at 100,000 miles of service or according to the owners manual, whichever is longer||Drain at 50,000 miles of service or according to the owners 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 3 years, whichever comes first. Otherwise, drain at twice the OEM interval for conventional oil.|
|Heavy Duty Off-Road Vocational||Follow the OEM drain interval (miles or hours) for synthetic oil up to 120,000 miles or 1 year, whichever comes first. Otherwise, drain at twice the OEM interval for conventional oil.|
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, manualtransmissions and other gear applications requiring anyof the following specifications: API GL-5, MT-1,MIL-PRF-2105E, Dana SHAES 234 (Formerly EatonPS-037), Mack GO-J, or the differential (hypoid) gear oilspecifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler. Can also be usedin axles where an API GL-4 lubricant is recommended.
AMSOIL SEVERE GEAR® (75W-140) provides superiorperformance and replaces competitors’ 75W-140, 80W-140 and 85W-140 gear oils. Use where these viscositiesare required by OEMs and where maximum viscosityprotection is needed for extreme severe-duty applications.
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.
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).
Keep out of the reach of children. Don't pollute. Return used oil to collection centers.
