AMSOIL SEVERE GEAR Synthetic Extreme Pressure (EP) 75W-90
Lubricant
Formulated for the severe operating
conditions of today's pick-up trucks, SUVs, heavy
equipment and other hard working vehicles.
Use in differentials, manual transmissions
or other gear applications where one or more of the
following standards are specified: API GL-5 &
MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton
PS-037) for 250,000 miles, Mack GO-J, Arvin/Meritor
0-76N (75W-90) & 0-76M (75W-140), plus hypoid
gear oil specifications from all foreign and domestic
manufacturers such as GM, Ford and Daimler Chrysler.
Can also be used in rear axles where API Service GL-4
lubricant is recommended.
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, busses, 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.

Follow
the OEM drain interval (miles or hours) for synthetic
oil up to 250,000 miles. Otherwise, drain at twice
the OEM interval for conventional oil. |
Follow
the OEM drain interval (miles or hours) for synthetic
oil. 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.
AMSOIL
SEVERE GEAR (75W-90) replaces competitors'
75W-90 and 80W-90 viscosity grades.
AMSOIL
SEVERE GEAR is compatible with conventional
gear oils, however mixing oils reduces the benefits
and nullifies the extended service life recommendations.
AMSOIL
SEVERE GEAR is compatible with most limited
slip differentials. If limited slip differential chatter
occurs, add AMSOIL Slip-LockT friction modifier additive.
Note: AMSOIL does not support
extended drain intervals where water contamination
occurs. Check and service the gear oil frequently
when water contamination is possible.
AMSOIL has optimized gear
lube performance for specific operating conditions.
However, AMSOIL gear lubes are multi-functional and
may be used in many different applications. This chart
conveys the best AMSOIL recommendation based on product
design and operating environment.
First row product recommendations
offer superior performance in the respective applications.
Second row product recommendations offer excellent
performance in the respective applications. The third
row is exclusive to SAE 80W-90 viscosity.
AMSOIL Severe GEAR 75W-90
(SVG) and 75W-140 (SVO) synthetic gear lubes have
a performance emphasis on the extreme pressure and
high heat of today's vehicle differentials.
AMSOIL Long Life 75W-90
(FGR) and 80W-140 (FGO) synthetic gear lubes have
a performance emphasis on 500,000 mile extended drain
intervals associated with larger sumps and lower operating
temperatures of over-the-road truck differentials.
AMSOIL 75W-90 synthetic
gear lubes will outperform conventional 80W-90 gear
oils in all applications and may be used as a replacement.AMSOIL
offers 80W-90 (AGL) synthetic gear lube for those
customers requiring this specific viscosity grade.
