AMSOIL Severe Gear® 75W-110
AMSOIL Severe Gear® 75W-110
Product Details
Engineered for high-demand applications, including trailer towing, heavy hauling, 4X4 off-road driving, commercial use and racing. Protects gears and bearings from scoring and wear. Excellent cold-flow properties. Outperforms all conventional gear oils. Recommended for all types of vehicles.
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.
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.
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.
Performance Features
- Superior Film Strength
- Controls Thermal Runaway
- Rust and Corrosion Protection
- Helps Reduce Operating Temperatures
- Maximum Efficiency
- Long Oil, Seal & Equipment 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 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.
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-110) provides superior performance and replaces competitors' 75W-110, 75W-90 and 80W-90 gear oils. It delivers better viscosity protection than Severe Gear 75W-90.
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.

Technical Information
Extra Information
Gear Oil and Motor Oil Are Not the Same
Gear oil differs from motor oil. While many motorists may assume SAE 90 gear oil is thicker than SAE 40 or 50 motor oil, they are actually the same viscosity; the difference is in the additives.
Motor oil contains additives such as detergents and dispersants to combat byproduct chemicals from gasoline or diesel ignition. Because an internal combustion engine has an oil pump and lubricates the bearings with a hydrodynamic film, extreme-pressure additives such as those used in gear oils are not necessary.
Motor oils and gear oils both have anti-wear additives, and they both must lubricate, cool and protect components, but gear oils may be placed under extreme amounts of pressure, creating a propensity for boundary lubrication, a condition in which a full-fluid lubricating film is not present between two rubbing surfaces. For example, differentials in cars and trucks have a ring-and-pinion hypoid gear set. A hypoid gear set can experience boundary lubrication, pressures and sliding action that can wipe most of the lubricant off the gears. To combat this extreme environment, extreme-pressure additives are incorporated into the oil. AMSOIL synthetic gear oils are formulated with an extra treatment of extreme-pressure additives in order to reduce wear and extend gear and bearing life.
Additional Differences
Because many of the components found in the drivetrain consist of ferrous material, the lubricant must prevent rust and possible corrosion to other materials. Rust and corrosion problems are not nearly as prevalent in engines.
The many small and intricate components that make up gear sets can be quite noisy and may be subjected to shock-loading. The viscosity and extreme-pressure formulation of gear oil quiets gears and dissipates shock-loading.
The rotating motion of the gear sets also tends to churn the lubricant, leading to foaming. If a gear lube foams, its load-carrying capacity is significantly reduced because the air suspended within the oil is compressible. For example, when the gear teeth come into contact with each other, any trapped air bubbles compress, reducing the thickness of the separating oil film. In turn, this reduction could lead to direct metal-to-metal contact between gear teeth and result in accelerated wear. The gear oil must have the ability to dissipate this entrapped air, ensuring a sufficient lubricating film that protects the gears against contact wear.
WHERE:
Stock or Modified
• Diesel pickup enthusiasts, contractors (small business owners) and over-the-road truckers (small fleets and owner/operators)
WHY:
• Superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life and 6X better wear protection
• API GL-5 (GL-5 has a lower coefficient of friction due to the higher concentration of EP additives over GL-4, and thus synchros can not engage as effectively.)
• Provides superior performance to competitors’ 75W 11O, 75W9O and 8OW-9O gear oils and delivers better viscosity protection than Severe Gear 75W-9O
