What’s the Best Heavy-Equipment Grease?

Grease must resist extreme impacts, fight wear, resist water washout and more to be considered the best heavy-equipment grease.

Greasing heavy-duty off-road equipment can be labor intensive and difficult. Pulling equipment out of service costs time and money, while the multitude and challenging location of grease points means some can be overlooked. Routine greasing, however, is important to protecting equipment against wear and maximizing service life. When it’s time to do the job, it pays to do it right with the best heavy-equipment grease you can find.

Since you’re on the AMSOIL blog, it won’t come as a surprise that we think AMSOIL Synthetic Polymeric Off-Road Grease is the best heavy-equipment grease to use. Now it’s up to us to prove why. Read on for more.

Heavy-equipment greasing challenges

Maintenance personnel face multiple challenges when greasing heavy equipment.

  • Difficult zerk (grease fitting) locations
  • Minimal standards for grease lubrication intervals
  • Proper grease selection

The problems of missed grease points

Even seasoned technicians can miss a grease fitting or two given their multitude and out-of-the-way location on some applications. Missing a grease interval can cause wear and, eventually, equipment failure.

Here’s one area where AMSOIL Synthetic Polymeric Off-Road Grease shines. Its exclusive synthetic polymeric system helps give this grease the ability to tenaciously stay in place and provide maximum load-carrying and impact resistance over extended service intervals, even in wet environments.

This means the grease stays in place longer to help protect if service is missed or delayed.

In addition, AMSOIL Synthetic Polymeric Off-Road Grease is formulated with 5 percent molybdenum disulfide (moly) for an extra level of protection, actively separating metal components when lubrication intervals are missed.

AMSOIL Synthetic Polymeric Grease is the best heavy equipment grease.

Excellent compatibility

Use of greases with incompatible thickening systems can result in equipment wear as certain incompatibilities can cause grease to harden or soften, reducing protection.

AMSOIL Synthetic Polymeric Off-Road Grease uses a calcium-sulfonate-complex thickener, which is compatible with nearly all major thickener types, including lithium-complex-thickened greases.

It provides peace of mind that you’re not going to accidentally cause problems due to incompatibility.


Stays in place despite extreme impact

Virtually all heavy-duty off-road equipment operates under heavy loads. The extreme impact common to off-road equipment forces pressure onto equipment pivot points, meaning the grease must prevent metal-to-metal contact. Lesser-quality greases cannot withstand the load and are squeezed out of the impact area, resulting in metal-to-metal contact and wear.

An off-road grease must resist extreme impact to be considered the best heavy-equipment grease.

Here again, AMSOIL Off-Road Grease delivers. It provides exceptional adhesion (ability to cling to components) and cohesion (ability to cling to itself). It is engineered to stay in place longer, providing outstanding lubrication.

Offers extended service life

Extending greasing intervals maximizes equipment uptime, but safely doing so requires using a grease capable of meeting the challenge.

Since it stays in place so well, AMSOIL Synthetic Polymeric Off-Road Grease reduces the amount of grease ejected during extreme operation. Its ability to extend service intervals and reduce grease consumption is application-dependent and operator-determined, so reach out to AMSOIL Technical Services for guidance ([email protected]; 715-399-8324 [TECH]).

That allows operators to either maintain their current maintenance schedule and use less grease per application, or extend the length of time between greasing intervals, saving time and labor.

Resists water washout

Heavy equipment is frequently exposed to moisture and 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.

In the industry-standard Water Washout Test (ASTM D1264), it loses only 1 percent volume, demonstrating its ability to remain in place and continue protecting against corrosion and wear.

The best heavy-equipment grease

Given its ability to remain in place despite extreme impacts, fight wear, promote compatibility, extend service intervals and resist water washout, we think AMSOIL Synthetic Polymeric Off-Road Grease is the best heavy-equipment grease out there.
