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.
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.
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

- 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-90) provides superior performance
and replaces competitors' 75W-90 and 80W-90 gear
oils. It delivers the best fuel efficiency and cold-temperature
performance of the Severe Gear oils.
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.
