Oils Analysis is the technique that consists on the study of the properties of the lubricants and the pollutants suspended in this with the purpose to supervise and to report appropriately, with significant and exact information, on the lubricant one and the condition of the machinery. With this technique in a practical way and in place we can know if a lubricant oil is capable to continue lubricating a machinery or if a change or another maintenance action becomes necessary. They usually take samples of the oil that is in the machine and it is compared with a standard pattern or with samples of the same maker's new oil. The analyzing device of oils carries out the comparison, determining the properties of the analyzed oil consequently.

Through an effective analysis of oil, the following benefits can be obtained:

	To establish appropriate intervals for the changes of oil and filters.
	To detect grade of contamination of the oils.
	To identify abnormal patterns of waste.
	To determine chemical degradation of the oil and preservatives.
