Impact Resistant – The Overlooked Quality in Grease

Greaseable components on heavy-duty trucks and equipment regularly operate in severe-service, extreme-pressure environments. Frequent high-load operation can push grease out of the application, which can leave components vulnerable. If the grease is not there no matter how good it is, what good is it?

AMSOIL Truck, Chassis and Equipment Grease is formulated to deliver maximum impact resistance! And it stays put. 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 and short term adhesion is the real issue!

Long Grease Service Life

Most trucking companies work to maximize the amount of time trucks are on the road, and inferior greases are not engineered to perform over the intended 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.

A Truck Grease with Superior Rust and Corrosion Protection

Water, snow and ice are encountered regularly, and they combine with salt and other road-deicing chemicals to promote accelerated corrosion on chassis and fifth-wheel components. AMSOIL Truck, Chassis and Equipment Grease clings tenaciously to metal surfaces, helping 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. 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.  The Calcium-Sulfonate Complex is superior to typical Lithium base greases.

  • Stays in place for excellent severe-service protection
  • Delivers peace of mind when maintenance is delayed
  • Protects against extreme impact and pressure
  • Helps seal out water, dirt and other contaminants

NLGI1 Truck Grease Applications

AMSOIL Truck, Chassis and Equipment Grease is ideal for mixed fleets that operate in severe service. It is recommended for heavy-duty over-the-road trucks 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. It 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.

Grease Compatibility 

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 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 Technical Services at (715) 399-TECH).


Maintaining a clean work environment is important when equipment greasing is performed. Wipe grease fittings clean prior to injecting grease to prevent contaminant ingestion. Maintain bearing housings one-third to one-half full of grease. Do not over-grease, as excessive heat buildup can result. Supplement standard grease maintenance by periodically cleaning and packing housings with fresh grease on an established maintenance schedule.


This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Safety Data Sheet (SDS). An SDS is available via the Internet at or upon request at (715) 392-7101. Keep Out of Reach of Children. Don’t pollute. Return used oil to collection centers.

* Note: AMSOIL Truck, Chassis and Equipment 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 on heavy equipment unless the system is designed to successfully pump a tackier grease.

Amsoil grease made a difference. The machine was smother and quiet. I could tell a difference.

Only grease I use

When it comes time to grease bearings or suspension components this is the grease to use, stays put and lasts. Gives long lasting protection and lubrication.

easy to work with

By  JEFF L,  a  Verified Buyer  from  Pensacola, FL  on  July 26, 2021
I really like this grease. I was sold on Amsoil years ago but only recently tried the grease – about a year ago. I use it on farm equipment as well as lawn equipment. I really like the fact that it doesn’t seem thin and run out like the previous grease I used. I also seem to have to add grease less often as when I grease now, the disc takes less pumps till full and I know it’s working because the gangs always spin nice and free by hand.


The reason we say our grease is the best is because AMSOIL has dedicated staff determined to keep it that way. Competitors see grease as a low level income generator and have actually degraded their finished products per one additive supplier. In addition, OEM grease products offer the very least protection as they lack any traceable quality control. Try AMSOIL Truck and Chassis Grease and see for your self.
