Synthetic oil provides many benefits for your engine. It cleans better, it cools better, and it lubricates better than conventional "regular" oil does. Synthetic oil costs more than regular oil, but it allows greater flexibility with oil change intervals; sooooo you save money in the long run. Plus, it will extend the life of your engine.
