The Difference Between Conventional Petroleum Motor Oils And Synthetic Motor Oils?

What’s the difference between conventional petroleum motor oils and synthetic motor oils?

Conventional petroleum oils are refined; AMSOIL is designed to provide the benefits a refined product cannot provide.

Conventional petroleum oils are refined from crude oil which is pumped from within the earth. The refining process, however, does not remove many of the impurities inherent in the crude oil. These impurities detract from the lubricating ability of the oil and contribute to deposit, sludge and varnish formation. AMSOIL synthetic motor oils are constructed in the laboratory and contain no impurities. AMSOIL synthetic motor oils have uniform molecular structures and are designed for specific lubricating applications. They are not affected by the high temperatures or demanding operating conditions of modern engines.
