AMSOIL Synthetic Polymeric Off-Road Grease (GPOR1, GPOR2) combines an over-based calcium-sulfonate
complex thickener and proprietary synthetic polymeric
technology to provide outstanding performance in heavy duty
AMSOIL developed an exclusive synthetic polymeric
system custom-built to provide performance benefits
specific to off-road equipment. This synthetic technology
helps give AMSOIL Off-Road Grease the ability to tenaciously
stay in place and provide maximum pound-out resistance over
extended service intervals, even in wet environments.
EXTREME IMPACT RESISTANCE
Greased components in heavy equipment are subjected to serious abuse. Virtually all
heavy-duty off-road equipment operates under heavy-load conditions. The extreme impact
common to off-road equipment forces all of that heavy load (pressure) onto places where
the equipment pivots, relying on the grease to prevent metal-to-metal contact.
Lesser-quality greases cannot withstand the load and are pounded out of the impact area.
When this occurs, heavily-loaded components are left unlubricated, which can result in
metal-to-metal contact and extreme amounts of wear.
AMSOIL Off-Road Grease's exclusive synthetic polymeric technology provides exceptional
adhesion (ability to cling to components) and cohesion (ability to cling to itself) properties.
It is engineered to resist pound-out better than other greases in heavily-loaded, extreme-pressure
applications and stay in place longer, providing outstanding lubrication over extended service
intervals and reducing the detrimental effects of missed grease intervals.
AMSOIL Synthetic Polymeric Off-Road Grease is heavily fortified with moly for maximum wear protection
to meet Caterpillar’s requirement for pin and bushing applications. Its high Timken OK load and
excellent four-ball wear and four-ball weld test results are proof of its exceptional load-bearing capacity.
Extended Service Life, Excellent Value
AMSOIL Synthetic Polymeric Off-Road Grease provides severe-duty performance over extended service intervals.
It resists pound-out and significantly reduces the amount of grease ejected during repetitive pounding action.
AMSOIL Synthetic Polymeric Off-Road Grease's ability to extend service intervals and reduce grease consumption
is application-dependent and operator-determined. However, field test results show that it can reduce grease
consumption by up to 50 percent. That allows operators to either maintain their current maintenance schedule
and use less grease per application, or extend the length of time between re-greasing intervals. Its superior pound-out
resistance combined with extended service intervals and superior protection result in reduced lubricant,
labor and equipment-replacement costs.
Excellent Water Washout Resistance
Greased components on heavy equipment are frequently exposed to water. AMSOIL Synthetic Polymeric Off-Road Grease resists
water washout to maintain a seal on greased components and help prevent water and other contaminants from entering wear-prone areas.
Calcium-Sulfonate Complex Thickener
AMSOIL Synthetic Polymeric Off-Road Grease features a calcium-sulfonate complex thickener for enhanced extreme-pressure performance.
Calcium-sulfonate complex is the ideal thickener for off-road grease. Its inherent extreme-pressure benefits deliver excellent impact resistance.
* 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, particularly in cold temperatures. AMSOIL GPOR2 pumps best in temperatures above
40°F; GPOR1 pumps best in temperatures above 0°F. A heavy follower plate may be necessary when pumping grease from larger package sizes.
AMSOIL Synthetic Polymeric Grease is not recommended for automatic or centralized lubrication systems on heavy equipment unless the system
is designed to successfully pump a tackier grease.
AMSOIL Synthetic Polymeric Off-Road Grease is ideal for heavy-duty, heavy-load-bearing applications operating in the adverse conditions
found in agricultural, construction, landscaping, logging and mining environments. Applications include power shovels, drag lines, wheel
and track loaders, excavators, bulldozers, skid steers, dump trucks and other heavy-duty equipment with heavily-loaded pivot pins, king
pins, bucket pins and bushings. AMSOIL Synthetic Polymeric Off-Road Grease is a perfect choice for equipment, including Caterpillar,
requiring 5 percent moly for pin and bushing applications. AMSOIL Off-Road Grease provides superior performance, protection and longevity
in heavy-duty, off-road applications.
AMSOIL Synthetic Polymeric Off-Road Grease is compatible with many other types of greases. However, it is recommended that when changing
greases, the equipment be cleaned of the old grease when possible or flushed with a liberal amount of Off-Road Grease while the mechanism is
in operation. Closely monitor the system for any inconsistencies. Grease compatibility questions should be referred to your AMSOIL representative
or AMSOIL INC.
