The lubricants have been produced to provide variety of qualification and quality that suitable for the purposes of lubrication. Qualified base oil has been enhance the quality by adding chemical additives in order to provide special properties i.e.
The quality and special properties of lubricant will be declined until it is unsuitable for using anymore. The deterioration of lubricant can be classified into 3 major aspects as follows,
1. Deterioration by Oxidation reaction.
2. Deterioration of additives.

Knowledge about lubricant
Viscosity is the first important fundamental property that must be considered in selecting the lubricant to suit with your automobiles. Lubricant with low viscosity creates thin lubricating film. Even though low viscosity lubricant cannot support much weight, it is able to insert to the engine parts that need lubrication rapidly and reduce heat very well. Also reduce the hard working of engine and fuel economy.
Lubricant with high viscosity creates thick lubricating film, able to resist high pressure better,...
