An oil change is essential for the peak performance of your engine. It lubricates the meticulous automotive parts and keeps them from rubbing against each other. Therefore, to extend the life of your engine, you must change the oil once every three months. Even if you forget to do so, don’t worry – your car will make sure to remind you. The engine will produce rumbling sounds, and the oil change light will illuminate. Every time you drive, you will witness excessive smoke trails. Moreover, your car will vibrate violently even when it is idle.
