AMSOIL Synthetic Polymeric Truck, Chassis and Equipment Grease (GPTR1, GPTR2) delivers excellent wear protection and extreme-pressure
performance over extended service intervals in medium- and heavy-duty applications. It combines
select base oils, proprietary synthetic polymeric chemistry, an advanced additive package and a
lithium-complex thickener for excellent impact resistance, reliable contaminant control and
Extreme Impact Resistance
Greasable components on heavy-duty trucks and equipment regularly operate in severe-service,
extreme-pressure environments. Frequent high-load operation increases the potential for grease to
pound out, which can leave components vulnerable to increased wear and corrosion. AMSOIL Truck,
Chassis and Equipment Grease is formulated to deliver maximum pound-out resistance. Its exceptional
adhesion and cohesion properties help keep the grease in place to seal out water and contaminants
and provide a protective barrier between metal components.
Long Service Life
Most trucking companies work to maximize the amount of time tractors are on the road, and inferior
greases are not engineered to perform over extended service intervals. The long intervals truckers
demand can result in components being left unprotected because the grease has squeezed out of
place. AMSOIL Truck, Chassis and Equipment Grease is engineered to remain intact for maximum
protection over extended service intervals. Owners/operators can be assured their equipment is
protected when the job demands additional time on the road between maintenance checks.
Superior Rust and Corrosion Protection
Over-the-road trucks and commercial equipment operate in all types of weather. Water, snow and ice
are encountered regularly, and they combine with salt and other road-deicing chemicals to promote
accelerated rust and corrosion on chassis and fifth-wheel components. AMSOIL Truck, Chassis and
Equipment Grease clings tenaciously to metal surfaces, helping to keep rain, snow and other
corrosive contaminants from penetrating greasable components. It is formulated with an advanced
additive package designed to combat the harmful effects of roadway contaminants, helping components
last longer and saving fleets money.
Maximum Extreme-Pressure Protection
AMSOIL Synthetic Polymeric Truck, Chassis and Equipment Grease is engineered for maximum protection
in extreme-pressure applications. It features a sophisticated additive package and exclusive
synthetic polymeric technology designed to provide long-term protection for heavily loaded
components. AMSOIL Truck, Chassis and Equipment Grease’s high Timken OK Load and excellent
Four-Ball Weld Test results prove its superior performance in extreme-pressure environments.
Ideal for Fleets
AMSOIL Truck, Chassis and Equipment Grease is ideal for mixed fleets that operate in severe
service. It provides exceptional protection and long service life for a broad range of
AMSOIL Truck, Chassis and Equipment Grease offers enhanced protection for extended component life,
reducing replacement costs. In addition, its long service life reduces the need for frequent
re-application (or requires less grease at each servicing), reducing maintenance costs.
Reduced Environmental Impact
Less-tenacious greases are ejected from greased components and pollute the surrounding environment.
AMSOIL Truck, Chassis and Equipment Grease is formulated to stay in place for long service
intervals, resulting in less grease pollution and reduced grease consumption. In addition, AMSOIL
Truck, Chassis and Equipment Grease is formulated without the use of barium, chlorine, antimony or
sulfur, which are all potentially harmful to the environment.
AMSOIL Synthetic Polymeric Truck, Chassis and Equipment Grease is recommended for heavy-duty
over-the-road tractors and trailers, delivery fleets, dump trucks, refuse haulers, utility fleets,
emergency service vehicles, sewer and septic trucks, snow removal vehicles, wreckers, municipal
service vehicles, equipment haulers, cement mixer trucks, airport support vehicles and more.
AMSOIL Synthetic Polymeric Grease provides exceptional performance in heavily loaded chassis
grease points, wheel bearings, axle assemblies, universal joints, pivot pins, fifth-wheel hitch
plates, steering linkages, spring pins, king pins, ball joints, water pump bearings and other
greased heavy-duty components.
AMSOIL Synthetic Polymeric Truck, Chassis and Equipment Grease is compatible with many other types
of grease. However, it is recommended that when changing greases, the equipment be cleaned of the
old grease or flushed with a liberal amount of AMSOIL Synthetic Polymeric Grease while the
mechanism is in operation. Closely monitor the system for any inconsistencies. Any grease
compatibility questions should be referred to your AMSOIL Dealer or AMSOIL INC.
*Note: AMSOIL Synthetic Polymeric Grease is designed to remain in place for long service
intervals. The same properties that provide its enhanced tenacity can also make it harder to pump.
A heavy follower plate may be necessary when pumping grease from larger package sizes. AMSOIL
Truck, Chassis and Equipment Grease is not recommended for automatic or centralized lubrication
systems unless the system is designed to pump a tackier grease.
