Analysis of Lubricating Oil Deterioration in Four-Wheeler

Lubricating oil used in vehicles deteriorates over the period of use, due to various causes. These include, high temperatures, great variety of contaminants like carbonic acid etc Ell. Deteriorated oil must be changed periodically, to ensure smooth performance of vehicle. Changing the lubricant too early, cause inefficient use of already depleting resources, also unwanted impact on environment. However, changing the oil too late may affect vehicle performance. Hence to compromise between these two necessities, optimum oil change point must be found.
