How to Select the RIGHT Grease?

Grease is not just grease, and though some of the distinctions between different types can be subtle, some can be significant. For example, just as a vintage vehicle is not the same as a high powered farm tractor, the best grease for each is not going to be the same either. And to take that even further, there are different types of greases and uses for the various parts of each of those vehicles themselves.

Knowing how to select the right grease for your particular application comes with understanding a bit more about the different types of greases and their uses. Luckily, we are here to help. Sure, you might be in need of automotive grease, but as mentioned, it isn’t a one-size-fits-all type of grease, and while some are more resilient to high heat temperatures, some are designed to handle higher pressures.

There isn’t a single “best grease,” but there is a “best grease for your situation.”

Grease Types and Grades

Knowing what grease to use comes with understanding the role that the grease is going to play. Sure, grease is designed to lubricate and protect, making your mechanics last and run smoothly, but it is important to consider the specifics.

Basic Lithium grease, for example, is designed for both high speeds and high pressure, and can withstand long hours of action or inaction, making it a popular grease. However, it is not recommended for heavy equipment or temperatures reaching 375 degrees.

On the other hand lithium complex grease can withstand temperatures up to 465 degrees, as well as high speeds. This is one of the best grease options for bearings in tractors or lawn mowers. And the options and applications of grease types and grades go on and on.

Take a look at the options below, and let’s figure out which is the best grease for you!

Types of Grease and Uses

G200EP Lithium Grease

AirTec Lube-Shuttle® G200EP is a premium Lithium 12-hydroxystearategrease designed for high speed, high pressure applications.  Designed for stability and function this grease will not quickly oxidize or get hard like many greases, instead G200EP will remain soft and continue to provide lubrication over long working hours or long downtime periods.  

Additionally, G200EP is formulated with a proprietary anti wear additive that actively works to keep metal surfaces smooth; minimizing wear and friction.  G200EP is a great grease for manufacturing equipment, lawnmowers, compact tractors, and general greasing.  

Limitations.   Not recommended for temperatures over 375°F, not recommended for heavy equipment or large pins and bushings
