Maintaining engine lubricating oil is a very important element in stretching the productive life of vehicle engines. Often referred to as the life blood of the engine, the oil circulates through the engine, performing critical functions necessary to maintain engine performance and maximize useful service life.
Engine oil needs to be changed on a regular basis because oils can lose their performance properties over time as a result of heat, contamination and chemical deterioration. Engine oils oxidize and become loaded with soot, wear debris and contaminants that can only be removed by draining the oil. Oxidative matter and acids formed as a byproduct of combustion also degrade the oil.
