Changing the oil in your car on a regular schedule is essential to keep the engine running smoothly. In fact to not change the oil as often as it requires it or to allow the oil level to drop dangerously low can damage the engine terribly. This harm can translate to big bucks in terms of car repair costs. Be smart about changing the oil in your car and never let this simple maintenance job be ignored or neglected all together.
