While your oil contains additives to prevent motor oil breakdown overtime it does occur. During the drain period motor oil becomes less efficient and effective because of the consumption of additives by your vehicle. Replacement of your vehicles motor oil will help prevent premature wear and extend engine life. Overtime the oil becomes filled with the harmful by-products of combustion to small for your engine filter to clean out. This causes your engine oil to become dirty decreasing its ability to perform valuable tasks such as: protection in high temperatures, Engine wear, Fuel Economy, Engine cleansing, and sludge control.
