AMSOIL Severe Gear® 75W-140
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.

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-140) provides superior performance and replaces competitors' 75W-140, 80W-140 and 85W-140 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 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
If a vehicle manufacturer recommends a 75W-90 gear lube, may a 75W-140 be used?
No. In most cases, 75W-140 gear lube is too thick to be used in place of 75W-90. For modified or non-stock differentials where a higher viscosity gear lube may be desired, AMSOIL typically recommends 75W-110. 
Can AMSOIL Severe Gear® be used in Harley-Davidson transmissions?
Yes. In Evolution 1340 and all Twin Cam Harley-Davidsons, AMSOIL recommends AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) or Severe Gear 75W-110 Synthetic EP Gear Lube (SVT). In older Harleys, such as Knuckleheads, Panheads and Shovelheads, AMSOIL Synthetic SAE 60 Motorcycle Oil (MCS) or Severe Gear 75W-140 Synthetic EP Gear Lube (SVO) is recommended.
Severe Gear® 75W-140 Synthetic Gear Lube (SVO)
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 and replaces competitors’ 75W-140, 80W-140 and 85W-140 gear oils. It delivers better viscosity protection than Severe Gear 75W-90 and 75W-110 when maximum protection is needed for severe-duty applications.
