Whats the difference between conventional petroleum motor oils and synthetic oils?
A 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 high temperatures or demanding operating conditions of modern engines. TOP Q I was always told to change my oil every 3000 miles if I wanted to properly maintain my vehicle. How is it possible to drive 25,000 to 35,000 miles without an oil change using AMSOIL? A AMSOIL synthetic motor oils are guaranteed to run 25,000 to 35,000 miles or one year in mechanically sound engines, providing, of course, the oil is kept free of contaminants by changing th
