The ?Man-Made? Engine Oil (Synthetic Oil Change)
April 20, 2025
If you own a newer vehicle, your vehicle’s manufacturer may require that it use synthetic oil instead of conventional oil. Synthetic oils are more stable, don’t break down as easily, and provide better engine protection than conventional oil. All those things can prolong the life of your engine and help it run better.
Imagine the damage that could happen to your engine as it operates at high speeds and very hot temperatures. Oil reduces the friction between the metal parts. That’s why it’s important that it maintains its lubricating properties for a long time, which synthetic oil does better than conventional oil.
Clean oil is better than dirty oil because it has fewer impurities. Synthetic oil is purer because of how it’s formulated and manufactured. Plus, as the outside temperatures change, the ability of oil to operate in those conditions is important.
For example, the colder it gets, it’s important for oil to flow easily to retain its lubricating properties. How thick a fluid is changes in different temperatures, and that thickness is known as viscosity, Synthetic oils are better at maintaining their viscosity throughout temperature changes.
It’s not only newer vehicles that can benefit from synthetic oil. If you have an older vehicle, synthetic oil may offer superior lubricating than conventional. Our technicians can advise you what’s the best oil for your vehicle and how often you need to change it, which may vary from the owner’s manual recommendations. You might find you’re able to change your oil less frequently than you used to with conventional oil.
Yes, synthetic oil is more expensive than conventional, so let us help you decide whether its advantages are worth the difference in price.
