 A Commitment to Excellence
As a jet fighter squadron commander Lieutenant Colonel Albert J. Amatuzio had ample opportunity to witness synthetic lubricants in action. These oils are used exclusively in jet engines because of three extraordinary performance characteristics: an ability to reduce friction and wear on engine components, an ability to function dependably at severe temperature extremes and an ability to withstand rigorous and lengthy engine operation without chemical breakdown.
Recognizing that these same benefits would prove invaluable in combustion engines, Amatuzio began conducting serious research in 1963. By 1966 he had formulated a synthetic motor oil and put it to use in vehicles in northern Minnesota. Throughout the late ’60s Amatuzio continued his research and development and sold commercially available synthetic oils under a variety of names. In 1970 he incorporated his own name into a commercially sold product called AMMOIL. In 1971 this product name was changed to AMZOIL and it continued to be sold commercially. The true milestone came in 1972 when AMZOIL became the first synthetic motor oil in the world to meet American Petroleum Institute criteria. The new lubricant performed like no other before it. When the first can appeared on the market in 1972, it signaled the birth of an entire industry. AMSOIL synthetic lubricants have expanded the boundaries of lubrication science and redefined the performance possibilities of modern machinery and engines.

Know the Facts - AMSOIL Saves You Money! See the cost comparison chart
AMSOIL extended drain intervals means fewer oil changes, long term savings and convenience. Even if you drive only 12,000 miles per year, the cost for AMSOIL motor oil is less than you pay for petroleum oil now! And you still get better wear protection, lower engine temperatures, improved fuel efficiency and easier cold-weather starts. All of these benefits add up to reduced operating costs and longer engine life. Change your oil and filter today and in 12 months change the oil and filter again. That’s it! What could be more convenient and good for your vehicle, too? 
The Right Choice for the Environment
Messages on the importance of being “green” and erasing our carbon footprints are everywhere these days. Consumers are becoming increasingly more conscious about how the purchasing decisions they make impact the environment. On the other hand, worries over rising costs of everyday purchases (fuel, groceries, etc.) have consumers scrambling to find a product they can feel good about that won’t break the bank.
