| AMSOIL
Severe Gear Synthetic Extreme Pressure (EP) Lubricants
are premium grade lubricants 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 prevent "thermal runaway"
- a phenomenon caused by a lubricant's inability to control
friction and increased heat under high-stress conditions.
By preventing 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.
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.

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-Lock™ 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.
