Automotive grease is a lubricant that protects car parts from friction and lubricates moving engine parts. Grease is a thick and oily product , and consists of a soap emulsified with mineral or vegetable oil.
When selecting a grease, you should consider the application and operating conditions as wrong selection may cause equipment damage. You should also consider the grease's components, including the base oil type, thickener type, and base oil viscosity.
The most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity.
Here are some types of grease:
-
Calcium greaseThis lubricant is best used at lower temperatures, as high temperatures may cause changes in its structure.Drop point is usually upto 110 C
-
Lithium greaseThis product is made from lithium soap stock. It has good high and low temperature characteristics and chemical stability. These greases have a relatively higher drop point ranging from 190 - 220 C
