Oil is essential to the healthy performance of a vehicle’s engine. A light may display on your dashboard when your vehicle is low on oil or when it is time to bring your vehicle in for an oil change; this is all for a reason.
An engine produces heat as it runs. Combining the combustion cycle with friction between the parts of the engine generates heat that has to be expelled. While fans and various other methods cool the engine as it runs, oil performs the job and continues to lubricate the engine as well. The lubrication provided by the oil in the engine prevents additional heat from building up by serving as a thin barrier between the metal parts of the engine.
