A fluid that is applied to lubricate pneumatic machines is known as a lubricator. Normally, it lessens the roughness among the surfaces and reduces the viscous heat generation when the faces are in working conditions for a long time. It maintains the performance and extends the service life of the automobiles. A lubricator is designed to feed the lubricating oil to the various elements of the automobile containing air pistons, valves, and air utensils.

The efficiency of every equipment depends on the lubricator. Besides the abrasion lessening, lubricator also minimizes the wear and tear of the elements throughout the service life of the device. The absence of the lubricator might create unwanted failures in the equipment. There are miscellaneous kinds of lubrication and lubricants utilized in equipment elements. Particular characteristics of effective lubricator are:

• The thermal stability of the lubricator should be high.
• The viscosity index of the lubricator should be high.
• Corrosion protection of the lubricator should be extraordinary.

10 % additives and 90 % base oil are used in the formation of a lubricator. However, the appropriate choice of the lubricator is essential to get the highest efficiency that influences the functioning of the apparatus.
