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.
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.

AMSOIL Synthetic Gear Lube Outperforms
Valvoline Gear Lube
High quality gear oils must lubricate, cool and protect geared systems.
They must also carry damaging wear debris away from contact zones
and muffle the sound of gear operation. Commonly used in differential
gears and standard transmission applications in commercial and
passenger vehicles, as well as a variety of industrial machinery, gear
oils must offer extreme temperature and pressure protection in order
to prevent wear, pitting, spalling, scoring, scuffing and other types of
damage that result in equipment failure and downtime. Protection
against oxidation, thermal degradation, rust, copper corrosion and
foaming is also important.
AMSOIL submitted its 75W-90 Synthetic Gear Lube (AGR) and
Valvoline 75W-90 Gear Lube to an independent laboratory for
quality comparison tests. The gear lubes were tested according to
ASTM testing procedures in several critical performance areas,
including oxidation resistance, viscosity retention and cold temperature fluidity. Oxidation resistance was measured using the
L-60-1 Thermal Oxidation Stability Test, viscosity retention was measured using the KRL Shear Stability Test and cold
temperature fluidity was measured using the Brookfield Viscosity Test. Additional load carrying, wear, extreme pressure and
scoring protection tests were performed exclusively on AMSOIL 75W-90 Synthetic Gear Lube using the L-37 High
Torque Axle Test and the L-42 High Speed Axle Test.
L-60-1 Thermal Oxidation Stability Test
Test Conditions
The L-60-1 Thermal Oxidation Stability Test measures a lubricant's rate of deterioration under severe oxidation conditions.
A measured sample of test lubricant is placed in a special gear case with two spur gears and a copper catalyst strip. The
gears are driven at 1,725 rpm at 163°C for a 50-hour duration, while air is bubbled through the sample.
Viscosity increase, deposits not soluble in pentane or toluene, carbon varnish and sludge deposits are measured upon test
completion. Test specifications are listed below.

Test Results
Because AMSOIL 75W-90 Synthetic Gear Lube is a premium lubricant designed for extended drain service, the test was
allowed to continue for 100 straight hours, double the standard test length. The Valvoline 75W-90 was run at both the
standard 50-hour test length and the double 100-hour test length. Test results indicate AMSOIL 75W-90 Synthetic Gear
Lube outperformed Valvoline at both test lengths.
Even at double the standard test length, AMSOIL 75W-90 scored almost four times better than industry test specifications
in the area of viscosity increase, while also greatly exceeding specifications in all areas of the test.
The photographs below show the superior deposit-control characteristics of AMSOIL 75W-90 Synthetic Gear Lube.
L-60-1 Thermal Oxidation Stability Test Results
AMSOIL 75W-90 (100 hours) Valvoline 75W-90 (100 hours) Valvoline 75W-90 (50 hours)
Even after enduring a double-length, 100-hour L-60-1 Thermal Oxidation Stability Test, AMSOIL 75W-90 Synthetic Gear
Lube produced significantly fewer deposits than the Valvoline 75W-90 run at a standard, 50-hour test.
KRL Shear Stability Test
Test Conditions
It is essential that high-quality gear lubes resist shear to ensure adequate oil film thickness and protection against friction and
wear. The KRL Shear Stability Test is used to determine the mechanical shear stability of lubricants containing polymer.
Mandatory under the SAE J-306 gear oil standard, the KRL Shear Stability Test makes use of a taper roller bearing in
order to shear the test fluid and determine the permanent drop in viscosity caused by the mechanical stress under practical
conditions. Under the specifications of SAE J- 306, the measured viscosity at 100°C (212°F) of an SAE 90 gear oil must
exceed 13.5 cSt after 20 hours of testing.
Test Results
AMSOIL 75W-90 Synthetic Gear Lube easily exceeded SAE J-306 specifications following the 20-hour test length and
was allowed to continue for a total of 192 straight hours, almost 10 times longer than the standard test length. Even after this
extended test, AMSOIL 75W-90 lost only 0.40 percent of its original viscosity, making it 99.6 percent shear stable.
Valvoline 75W-90 Gear Lube, on the other hand, failed the test during the initial 20-hour testing period, losing 14 percent of
its original viscosity.
Brookfield Viscosity Test
Test Conditions
The Brookfield Viscosity Test (ASTM 0-2983) is used to determine the internal fluid-friction of a
lubricant during cold temperature operation. The lubricant sample is chilled in a -40°C (-40° F) air
bath for 16 hours, and a Brookfield viscometer determines the torque required to shear the lubricant.
The lower the cold temperature viscosity (measured in centipoise), the better the cold temperature
protection. ASTM specifications dictate that 75W-90 gear oils measure less than 150,000 cP at
test completion.
Test Results
AMSOIL 75W-90 Synthetic Gear Lube easily passed the Brookfield Viscosity Test, measuring
88,000 cP at test completion, 42 percent less than test limits. The superior cold temperature properties of AMSOIL
75W-90 Synthetic Gear Lube ensure quicker oil flow, enhanced component protection and improved fuel efficiency.
Many conventional lubricants fail to pass the Brookfield Viscosity Test due to the paraffinic (wax) content in their base oils.
Valvoline Gear Lube passed the test at 130,000 cP, only 13 percent lower than test limits.

1-37 High Torque Axle Test
The gears protected by AMSOIL 75W-90 Synthetic gear Oil showed little or no rippling, ridging, pitting or deposits
following the L-37 High Torque Axle Test.
Test Conditions
The L-37 High Torque Axle Test is used to evaluate a gear lubricant's load-carrying, wear and extreme pressure
characteristics in hypoid gears operating under both high-speed/low-torque and low-speed/high-torque conditions. A Dana
Model 60 hypoid gear axle is used with either coated or uncoated drive gear and pinion to drive two dynamometers from an
eight-cylinder, 5.7-liter gasoline engine. With the axle filled with the test lubricant, the high-speed/low-torque test is
performed for 100 minutes, with the gears visually assessed afterwards. Next, the low-speed/high-torque test is run for 24
hours, followed by a thorough inspection of the gears. Performance relative to API GL-5 and MIL-PRF-2105E
specifications is assessed based on tooth surface rippling, ridging, pitting and wear, deposits and discoloration.
Test Results
Testing on AMSOIL 75W-90 Synthetic Gear Oil was conducted using uncoated gear and pinion. The AMSOIL lubricant
passed on all counts and showed little to no rippling, ridging, pitting or deposits, indicating that AMSOIL 75W-90 provides
superior protection and performance under extreme pressure conditions.
L-42 High Speed Axle Test
Test Conditions
The L-42 High Speed Axle Test evaluates the antiscoring characteristics of a gear lubricant operating under high-speed and
shock-loading conditions. A Spicer Model 44-1 hypoid gear axle is driven by a 5.7 liter, V8 gasoline engine with a
four-speed truck transmission and two high-inertia dynamometers and hard accelerated to 100 mph. The axle is periodically
shock-loaded through a dynamometer to simulate high shock-loading conditions. The axle is accelerated through the gears
to 1,050 r/min and decelerated to 530 r/min. This cycle is repeated five times, followed by 10 shock loadings. In order to
meet API GL-5 and MIL-PRF-2105E gear oil specifications, scoring must be equal to or better than gears tested with a
reference oil.
Test Results
AMSOIL 75W-90 Synthetic Gear Oil easily passed the L-42 High Speed Axle Test, receiving a significantly better rating
than the reference oil and leaving little to no scoring on the ring and pinion.

scoring protection tests were performed exclusively on AMSOIL 75W-90 Synthetic Gear Lube using the L-37 High
Torque Axle Test and the L-42 High Speed Axle Test.
L-60-1 Thermal Oxidation Stability Test
Test Conditions
The L-60-1 Thermal Oxidation Stability Test measures a lubricant's rate of deterioration under severe oxidation conditions.
A measured sample of test lubricant is placed in a special gear case with two spur gears and a copper catalyst strip. The
gears are driven at 1,725 rpm at 163°C for a 50-hour duration, while air is bubbled through the sample.
Viscosity increase, deposits not soluble in pentane or toluene, carbon varnish and sludge deposits are measured upon test
completion. Test specifications are listed below.

Test Results
Because AMSOIL 75W-90 Synthetic Gear Lube is a premium lubricant designed for extended drain service, the test was
allowed to continue for 100 straight hours, double the standard test length. The Valvoline 75W-90 was run at both the
standard 50-hour test length and the double 100-hour test length. Test results indicate AMSOIL 75W-90 Synthetic Gear
Lube outperformed Valvoline at both test lengths.
Even at double the standard test length, AMSOIL 75W-90 scored almost four times better than industry test specifications
in the area of viscosity increase, while also greatly exceeding specifications in all areas of the test.
The photographs below show the superior deposit-control characteristics of AMSOIL 75W-90 Synthetic Gear Lube.

Even after enduring a double-length, 100-hour L-60-1 Thermal Oxidation Stability Test, AMSOIL 75W-90 Synthetic Gear
Lube produced significantly fewer deposits than the Valvoline 75W-90 run at a standard, 50-hour test.
KRL Shear Stability Test
Test Conditions
It is essential that high-quality gear lubes resist shear to ensure adequate oil film thickness and protection against friction and
wear. The KRL Shear Stability Test is used to determine the mechanical shear stability of lubricants containing polymer.
Mandatory under the SAE J-306 gear oil standard, the KRL Shear Stability Test makes use of a taper roller bearing in
order to shear the test fluid and determine the permanent drop in viscosity caused by the mechanical stress under practical
conditions. Under the specifications of SAE J- 306, the measured viscosity at 100°C (212°F) of an SAE 90 gear oil must
exceed 13.5 cSt after 20 hours of testing.
Test Results
AMSOIL 75W-90 Synthetic Gear Lube easily exceeded SAE J-306 specifications following the 20-hour test length and
was allowed to continue for a total of 192 straight hours, almost 10 times longer than the standard test length. Even after this
extended test, AMSOIL 75W-90 lost only 0.40 percent of its original viscosity, making it 99.6 percent shear stable.
Valvoline 75W-90 Gear Lube, on the other hand, failed the test during the initial 20-hour testing period, losing 14 percent of
its original viscosity.
Brookfield Viscosity Test
Test Conditions
The Brookfield Viscosity Test (ASTM 0-2983) is used to determine the internal fluid-friction of a
lubricant during cold temperature operation. The lubricant sample is chilled in a -40°C (-40° F) air
bath for 16 hours, and a Brookfield viscometer determines the torque required to shear the lubricant.
The lower the cold temperature viscosity (measured in centipoise), the better the cold temperature
protection. ASTM specifications dictate that 75W-90 gear oils measure less than 150,000 cP at
test completion.
Test Results
AMSOIL 75W-90 Synthetic Gear Lube easily passed the Brookfield Viscosity Test, measuring
88,000 cP at test completion, 42 percent less than test limits. The superior cold temperature properties of AMSOIL
75W-90 Synthetic Gear Lube ensure quicker oil flow, enhanced component protection and improved fuel efficiency.
Many conventional lubricants fail to pass the Brookfield Viscosity Test due to the paraffinic (wax) content in their base oils.
Valvoline Gear Lube passed the test at 130,000 cP, only 13 percent lower than test limits.

1-37 High Torque Axle Test
The gears protected by AMSOIL 75W-90 Synthetic gear Oil showed little or no rippling, ridging, pitting or deposits
following the L-37 High Torque Axle Test.
Test Conditions
The L-37 High Torque Axle Test is used to evaluate a gear lubricant's load-carrying, wear and extreme pressure
characteristics in hypoid gears operating under both high-speed/low-torque and low-speed/high-torque conditions. A Dana
Model 60 hypoid gear axle is used with either coated or uncoated drive gear and pinion to drive two dynamometers from an
eight-cylinder, 5.7-liter gasoline engine. With the axle filled with the test lubricant, the high-speed/low-torque test is
performed for 100 minutes, with the gears visually assessed afterwards. Next, the low-speed/high-torque test is run for 24
hours, followed by a thorough inspection of the gears. Performance relative to API GL-5 and MIL-PRF-2105E
specifications is assessed based on tooth surface rippling, ridging, pitting and wear, deposits and discoloration.
Test Results
Testing on AMSOIL 75W-90 Synthetic Gear Oil was conducted using uncoated gear and pinion. The AMSOIL lubricant
passed on all counts and showed little to no rippling, ridging, pitting or deposits, indicating that AMSOIL 75W-90 provides
superior protection and performance under extreme pressure conditions.
L-42 High Speed Axle Test
Test Conditions
The L-42 High Speed Axle Test evaluates the antiscoring characteristics of a gear lubricant operating under high-speed and
shock-loading conditions. A Spicer Model 44-1 hypoid gear axle is driven by a 5.7 liter, V8 gasoline engine with a
four-speed truck transmission and two high-inertia dynamometers and hard accelerated to 100 mph. The axle is periodically
shock-loaded through a dynamometer to simulate high shock-loading conditions. The axle is accelerated through the gears
to 1,050 r/min and decelerated to 530 r/min. This cycle is repeated five times, followed by 10 shock loadings. In order to
meet API GL-5 and MIL-PRF-2105E gear oil specifications, scoring must be equal to or better than gears tested with a
reference oil.
Test Results
AMSOIL 75W-90 Synthetic Gear Oil easily passed the L-42 High Speed Axle Test, receiving a significantly better rating
than the reference oil and leaving little to no scoring on the ring and pinion.

PRODUCT DESCRIPTION
AMSOIL Universal Synthetic Marine Gear Lube is an exclusive AMSOIL formulation of synthetic base oils and high
performance additives that address the specific concerns of marine applications. It is extreme pressure (EP) additive fortified
for superior protection of fast accelerating, high torque/horsepower engines. It protects against shock loading from cavitation
of heavily loaded engines.
AMSOIL Universal Synthetic Marine Gear Lube is water resistant. It maintains extreme pressure protection even when
contaminated with as much as 10% water. It promotes longer seal life, preventing excessive water leakage. AMSOIL
Universal Synthetic Marine Gear Lube protects against rust and is compatible with aluminum, copper and brass alloys.
APPLICATIONS
AMSOIL Universal Synthetic Marine Gear Lube is recommended for fresh and salt water applications requiring either
75W-90 or 80W-90 viscosity grade and meeting either API GL-4 or GL-5 performance standards.
Examples of AMSOIL Universal Synthetic Marine Gear Lube applications include:
Outboard Lower Units:
Mercury/Mariner, Johnson/Evinrude, Bombardier, Honda, Yamaha, Suzuki, Force/US Marine, Nissan
Tohatsu, Harbormaster Marine Outboard Drives, Sears Gamefisher and Seagull

Marine gear oils operate in environments subject to water contamination. The chart below demonstrates the ability of
AMSOIL Universal Synthetic Marine Gear Lube to maintain designed qualities such as extreme pressure/anti-wear
performance and resistance to foaming, even when subjected to 10% water contamination.
The Falex Procedure is measurement of a gear lube's extreme pressure and anti-wear properties. A high value in the Falex
Extreme Pressure Test relates to extra extreme pressure protection. AMSOIL Universal Synthetic Marine Gear Lube is not
affected by water and provides 50% more extreme pressure protection for long gear and bearing life.
The presence of foam in a lubricant disrupts oil film and promotes wear. Water contamination can increase the likelihood of
foaming. Industry standard testing demonstrates zero foam in both new and water-contaminated AMSOIL Universal
Synthetic Marine Gear Lube. Other conventional gear lubes can foam when mixed with water, as seen in the graph.

AMSOIL Slip-Lock Differential Additive
Effectively Eliminates Gear Housing Chatter
When making a turn, the outer wheels of a vehicle must travel faster than the inner
wheels. It is up to the differential to act as a balance arm, establishing constant
equilibrium of torques and forces between the left-hand and right-hand driven wheels.
In standard (or open) differentials, power is directed to the wheel offering the least
resistance. This works well when making a turn, but in a situation where one wheel is
lifted off the ground, it causes the suspended wheel to turn while the other remains
motionless.
Limited-slip (or positraction) and locking differentials are traction-increasing devices.
Locking differentials transfer all available torque to both wheels. The teeth of the
spider assembly engage with those on the locker clutch, causing both axle shafts to
operate as one. Locking differentials don't allow one drive wheel to spin while the
other remains stationary. Instead, they keep both wheels in drive mode, but unlock to
permit different wheel speeds when turning. The engaging and disengaging of the teeth on automatic locking differentials
often causes a banging and clunking sound. Manual locking differentials usually use an electric motor or vacuum
diaphragm to engage the locker, reducing this noise.
Limited-slip differentials allow different wheel speeds when turning, but when one wheel loses traction, greater torque is
transferred to the wheel offering more resistance. Limited-slip differentials make use of friction between clutch plates, as
opposed to the meshing teeth employed by locking differentials. Transferring less torque per side, limited-slip differentials
are generally smoother and quieter than locking differentials, but still sometimes "chatter" when transferring torque to the
wheel with traction.
In some differential applications, a friction modifier additive is
necessary to reduce chatter. AMSOIL Slip-Lock Differential
Additive is formulated with advanced friction modifiers and is
designed to eliminate gear-housing chatter in cars, trucks and
SUVs equipped with limited-slip, positraction and locking
differentials. It also reduces the banging and clunking associated
with automatic locking differentials.
AMSOIL Slip-Lock Differential Additive is formulated for use
with both synthetic and petroleum gear lubricants and safely
replaces manufacturer recommended friction modifiers. Its
convenient flip-top dispenser provides quick and easy application
to the gear housing. One four-ounce bottle of Slip-Lock treats
differential capacities of two to four quarts. It is not for use in
automatic transmissions or other applications requiring ATF.
NOTE: AMSOIL Synthetic Gear Lubes do not require the use of this additive. However, not all differentials respond the
same and if chatter is noticed, the addition of AMSOIL Slip-Lock will eliminate it. For chattering differentials not running
AMSOIL Gear Lube, this product is an excellent solution to the problem.

convenient flip-top dispenser provides quick and easy application
to the gear housing. One four-ounce bottle of Slip-Lock treats
differential capacities of two to four quarts. It is not for use in
automatic transmissions or other applications requiring ATF.
NOTE: AMSOIL Synthetic Gear Lubes do not require the use of this additive. However, not all differentials respond the
same and if chatter is noticed, the addition of AMSOIL Slip-Lock will eliminate it. For chattering differentials not running
AMSOIL Gear Lube, this product is an excellent solution to the problem.

Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check and service the
gear oil frequently when water contamination is possible. 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.

Helpful Differential Recommendations:
Flush (drain) as much of the old fluid out.
Differential fluid capacity depends on ring gear and axle housing size.
Do not over/under fill differential. This could mean a capacity difference of a quart or more and may cause over
heating problems. (See the owner’s manual for proper fill level)
AMSOIL gear oils are formulated with friction modifiers for limited slip differential applications. There is no need
to add limited slip or additional additives.
After changing the differential fluid, drive the vehicle in 7 or 8 figure eight turns, so new lubricant can work its way
into the axle assembly.

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.
Superior Film Strength
Controls Thermal Runaway
Rust and Corrosion protection
Reduced Operating Temperatures
Improved Efficiency
Longer Oil, Seal, & Equipment 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.
NORMAL
Cars, SUV, Light & Medium Duty Trucks Drain at 100,000 miles of service or according to the owner’s manual,
whichever is longer
Severe
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 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.
