Getting an oil change is generally a pretty common and uneventful experience. However, it can be costly depending on the type of oil your car should have. You will likely hear your mechanic talk about synthetic oil, but before you give the go-ahead on this pricey job, make sure you know what the difference is.Synthetic oil is, at the base, a cleaner oil. It’s refined, distilled, and purified to get rid of any debris and impurities that regular oil possesses. This means that the oil circulates through your engine and comes out cleaner. If your engine is running cleaner, that usually means it’s going to run longer. Synthetic oil also performs better at more extreme temperatures. It is able to flow smoothly through the cold and the heat, while regular oil can break down and expose your engine to damage. However, it may not be worth the money. The biggest difference you will see with synthetic oil versus regular oil is how often you need to change it. It is recommended that you change your oil about every 3,000 to 5,000 miles, but with conventional oil it’s about 7,500. It all really comes down to how long you want your vehicle to run on a single oil change.
