Product
Description
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.
Performance
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.

Temperature Extremes
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.
Applications
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.
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 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 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 and better fuel
efficiency than SEVERE GEAR 75W-140.
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 oils.
AMSOIL SEVERE GEAR® is compatible
with most limited slip
differentials. If limited slip
differential chatter occurs, add
AMSOIL Slip-Lock™ friction modifier
additive.
HEALTH &
SAFETY
This product is not expected to
