Why Oil Changes Are Important

Oil's primary purpose is to keep your vehicle's fast-moving engine parts lubricated so that they generate less friction and heat. Better lubrication leads to more efficient engine performance, and it helps to reduce wear and tear on your engine. In other words, oil can help to improve fuel economy and overall vehicle longevity.

But why do you need to change your oil regularly? It all boils down to the fact that oil doesn't last forever. Oil degrades over time, eventually turning into a sludgy substance that is far less effective than fresh oil. Oil can also grow contaminated with dirt and the tiny metal particles that break off your engine's parts. Leaving oil unchanged can have a wide range of adverse effects on your car, so it's best to stay on top of regular oil changes.
