What Does Oil Do?

oilRoutine maintenance on your vehicle is just that—routine. So it isn’t often you think about why something needs to be done. Some drivers simply follow their owner’s manual while others listen to the advice of friends and family. One important part of routine maintenance is changing the oil regularly. This is an extremely important part of owning a car, yet many owners aren’t sure what oil does. We at Friendly Ford are here to answer that question: just what does oil do?

Oil works in three ways to keep the engine operating smoothly. First, it helps keep the metal parts that are constantly mashing together lubricated to prevent any damage to the engine. It also carries away any dirt, grime, and metal shavings between parts.

Second, the engine is constantly setting off very small, contained explosions within its cylinders. That generates a lot of heat; oil helps to remove some of that heat and heat caused by friction between the moving parts.

Third, it keeps carbon and varnishes from building up in the engine. A very expensive engine cleaning is the only effective way to remove carbon and varnish build up. The worst that can happen if you don’t change your oil is your engine could seize up entirely. Trust us; that’s not a bill you want to pay!
