The 6 Best Synthetic Oils Available

When it comes to running your engine optimally, synthetic oil is the best choice. The following post will examine why synthetic oil is best followed by what I consider the best synthetic oil that is available today.

Why Synthetic Oil?

Synthetic oil is not only refined, it is distilled, purified and then further broken down into basic molecules.

By doing this any impurities that are present in the crude oil are removed and it also allows the basic molecules to be changed to suit engine needs.

Synthetic oil will:

• Keep your engine cleaner
• Better protect engine wear
• Flows better in low temperatures
• Protects the engine in high temperatures
• Protects turbocharger engine parts
