Synthetic oils can outlast basic petroleum oil by at least three times. While a car that runs on regular oil might require an oil change every 3,000 miles, cars running on synthetic oil might be able to run much longer -- between 9,000 and 15,000 miles.

Premium additives found in most synthetic oils help an engine run longer and cleaner -- without buildup -- than conventional petroleum oil. The additives also allow the oil to last longer than regular motor oil without as great a change in composition or performance.

Using synthetic oil in a vehicle helps a car to withstand extreme hot and cold temperature. This in turn adds longevity to the life of the vehicle’s engine and can decrease the need for regular oil changes.

Using synthetic oil does not guarantee more mileage between oil changes. The type of vehicle, its age and the type of oil it requires can determine the length of time synthetic oil will last before it needs to be changed.
