AMSOIL Synthetic Gear Lubes
Modern vehicles are
designed with more horsepower and torque than in years past,
allowing them to haul and tow heavier and heavier loads.
This results in higher gear loading and hotter running
differentials. In addition, factors such as increased
interior space and lower floor boards push axles higher into
the vehicle's body, reducing air flow and increasing heat.
The closer proximity of the axles to the exhaust system also
effectively raises heat, while more aerodynamic body styles
and air dams result in restricted air flow to the
differentials.
A number of factors cause
SUV, pickup truck and van gears to operate under more severe
conditions than over-the-road trucks, contributing to
increased temperatures, higher gear loading and shorter
drain intervals. First, these vehicles have smaller gears
that must handle higher loads per square inch of surface
area. Second, their smaller sump sizes (and lower volume of
gear lube) cannot dissipate heat as well as larger sump
sizes. Third, air flow is significantly reduced compared to
over-the-road trucks. Fourth, these vehicles are subject to
more frequent stop and go driving conditions and are more
susceptible to moisture from condensation due to varying
temperature fluctuations.
The AMSOIL Solution
In order to optimize its
gear lubes for modern applications, AMSOIL has updated its
gear lube formulations.
SEVERE GEAR™
Synthetic Extreme Pressure Gear Lubes (75W-90 & 75W-140)
Specially formulated for
severe duty applications, AMSOIL SEVERE GEAR™ Synthetic
Extreme Pressure Gear Lubes are excellent for vehicles that
experience towing, hauling, steep hill driving, commercial
use, racing, off-road use, rapid acceleration, stop and go
driving and high ambient temperatures. AMSOIL SEVERE GEAR™
Gear Lubes are formulated with increased levels of premium
quality additives, allowing improved limited-slip and
locking differential performance.
And with high viscosity indices, SEVERE GEAR™ Gear Lubes
provide an extra level of protection at high temperatures.
Extra additives provide additional insurance against wear in
case of a lubricant film breach. These additives provide an
iron sulfide barrier coating that effectively prevents
micro-welding that leads to heat and friction. This allows
AMSOIL SEVERE GEAR™ Gear Lubes to 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™ Gear Lubes
inhibit component damage and rapid lubricant degradation.
SEVERE GEAR™ Synthetic 75W--90 Gear Lube (SVG) replaces
Series 2000 Synthetic 75W-90 Gear Lube (TGR).
SEVERE GEAR™ Synthetic 75W--140 Gear Lube (SVO) replaces
Series 2000 Synthetic 75W-140 Gear Lube (TGO).

Long Life
Synthetic Gear Lubes (75W-90 & 80W-140)
AMSOIL Long Life
Synthetic Gear Lubes are formulated with new and enhanced
additives designed specifically for extended drain intervals
of up to 500,000 miles in over-the-road trucks. Long Life
Synthetic Gear Lubes are engineered to protect gears better
than conventional gear oils, resisting acid, carbon and
varnish formation and oxidative breakdown. Their superior
shear stability allow them to maintain their viscosity
during extended service. The enhanced 80W-140 formulation
replaces the former 85W-140 formulation, allowing a greater
operating range and improved cold temperature performance.
AMSOIL Long Life Synthetic Gear Lubes are available in five
gallon buckets, excellent for use with lube dispensing
pumps.
Long Life Synthetic 75W-90 Gear Lube (FGR) replaces
Synthetic 75W-90 Gear Lube (AGR). Long Life Synthetic
80W-140 Gear Lube (FGO) replaces Synthetic 85W-140 Gear Lube
(AGO).

80W-90
Synthetic Gear Lube
The 80W-90 gear lube
market is mineral oil based. New reformulated AMSOIL 80W-90
Synthetic Gear Lube is designed as a high quality synthetic
replacement for mineral gear oils. It is a multifunctional
product designed to surpass the requirements of equipment
and automotive applications calling for an SAE 80W-90
viscosity grade. Its naturally high viscosity index and
shear stable construction provide improved cold temperature
performance, while extreme pressure additives provide
excellent protection for gears and bearings. AMSOIL 80W-90
Synthetic Gear Lube is competitively priced, making it an
excellent choice for cost conscious customers.
