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.

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.

| Heavy Duty Class 8 Line

Follow the
OEM drain interval (miles or hours) for
synthetic oil up to 250,000 miles or three years,
whichever comes first. Otherwise, drain
at twice the OEM interval for conventional
oil. |
| Vocational/Delivery |
Follow the
OEM drain interval (miles or hours) for
synthetic oil up to 120,000 miles or three years,
whichever comes first. Otherwise, drain
at twice the OEM interval for conventional
oil. |
| 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. 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 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 oils 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.
