Why Do We Change Our Oil and What Does it Do?

February 27th, 2017 by

As a car owner it is incredibly important to take notice of the small things that are going on inside of your car. One thing that is incredibly important to pay attention to is the sounds of your engine and any irregular sounds that make you take a closer look. Sounds like this could mean it is time to change your oil which is an easy fix and is essential to keeping your car running for a long time.


The engine oil that is in your car is like the blood in your body and it keeps your engine running smoothly. Oil works to lubricate the internal parts of your engine and help to make sure the complicated mechanisms keep running how they are designed. Additionally, the oil works to keep your engine from overheating and causing bigger issues.

We change the oil in our cars because when oil becomes older it breaks down and does not properly cool and lubricate the engine as it is supposed to. Used oil is less effective because when oil is older it becomes thinner and less likely to cool or lubricate the engine. Making sure that you change your oil at the appropriate time helps to ensure your engine lasts for years!

Engine oil is one of the most important parts of your engine and makes sure that your car runs safely.
