Why is it so important to change the engine oil regularly?

The primary function of the engine oil is to lubricate the engine’s internal moving parts. In order for the oil to fulfill this function it has to posses certain properties. As these properties diminish over time and distance it is essential to replace the engine oil periodically in order to maintain reliable engine lubrication. During combustion soot and gases are produced which leak past the piston rings into the crankcase. Modern oils are designed to absorb these by-products and keep them suspended to prevent the formation of sludge deposits. Ultimately the oil will become saturated and it will loose its ability to do the jobs it is intended to do. Since engine oil is a cocktail of base oil, synthetic or mineral, which is enhanced with chemicals, it is inevitable that the strain of heat, oxygen and impurities will graduyally reduce its ability to meet the engine’s demands. In the early stages of deterioration some excessive wear may occur which will probably go unnoticed to start with. Poor lubrication over a long period will lead to premature engine failure. Engine oil left in the engine for a very long time will ultimately coagulate and lead to sudden engine failure. Our advice is never to exceed the oil change intervals and to use the oil recommended by the car’s manufacturer. The oil specified may vary for different climatic conditions. Oil change intervalls vary for different operating conditions.
