Your vehicle is a very important part of your life. Basic vehicle maintenance is kind of like preventive care for your health. For example, having your oil changed at periodic intervals will help prolong the life of your investment and help you avoid major expenses in the long run. An oil change is vital to the optimum performance of your vehicle because oil serves three vital roles that directly impact the longevity of the engine: it coats, it cools, and it cleans. These are known as the 3 C’s of oil.
