Getting your car’s engine oil changed is one of the least expensive auto maintenance services. Despite it being relatively inexpensive, having your oil replaced regularly and with correct type of oil, plays a critical role in making your vehicle last longer and saving you money. If you don’t believe you have the time or money to get your oil changed when needed and with correct type of oil, and you choose to wait, eventually the oil in the engine will deteriorate, becoming more like sludge. It will clog your car’s engine. Engines are expensive to clean, and replacing a damaged piston, cam shaft or crank shaft is not a repair bill you want to receive.
