synthetic gear lubes are formulated to protect gears
operating in heavily loaded conditions, whether or
not the gears operate with full film lubrication.
Superior film strength and viscosity retention offer
superior portection in full film regimes, while top-quality
extreme pressure agents protect when a full lubricating
film does not separate gear surfaces.
The thermal durability of AMSOIL
synthetic gear lubes ensures extreme pressure protection
after extended exposure to extreme temperatures. The
extreme pressure agents in conventional gear lubes
sometimes lose their effectiveness after extended
exposure to high temperatures, leaving gears vulnerable
to metal-to-metal contact and wear.
GEAR Synthetic Extreme Pressure Gear Lubes
(75W-90, 75W-110 & 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.

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).
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).
