AMSOIL Inc. is an American corporation based in Superior, Wisconsin that primarily formulates and packages synthetic lubricants and filters. The company's advertising slogan is The First in Synthetics.
As a jet fighter squadron commander, Lieutenant Colonel Albert J. Amatuzio had opportunity to witness synthetic lubricants in action. These oils are used exclusively in jet engines because of their ability to reduce friction and wear on engine components, function dependably at temperature extremes and withstand lengthy engine operation without chemical breakdown.
Recognizing these same benefits would prove invaluable in combustion engines, Amatuzio began conducting research in the early 1960s. He soon developed and sold commercially available synthetic oils under a variety of names. The milestone came in 1972 when AMSOIL became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. 
AMSOIL has gone on to formulate synthetic lubricating oils for engine and gear applications, including those for specialized vehicles and severe operating conditions. In addition, AMSOIL has developed fuel additives, filtration systems and other companion products that supplement and extend lubricant performance.
AMSOIL products are blended and packaged at the AMSOIL Center in Superior, Wisconsin. It serves as the hub of a global distribution network. Regional warehouses fulfill North American orders; AMSOIL bottles, cases, drums and totes are shipped worldwide.
AMSOIL products are distributed through a network of independent dealers who work with their customers and accounts. Dealers map out lubrication programs and identify ways to reduce costs. AMSOIL customers and accounts can order from their servicing dealer or ordering directly from AMSOIL INC.
Research and validation
The chemical and engine-test laboratories are equipped with analytical instruments needed to design and develop synthetic technology.
Lubricant studies have involved vehicles requiring severe lubricant applications: taxicabs, delivery fleets, police and emergency vehicles, over-the-road transports and heavy-duty construction and industrial machinery.
Additional testing takes place weekly on race tracks across North America. AMSOIL lubricants are used by racing teams operating off-road trucks, stock cars, high-powered boats, dirt bikes and snowmobiles.
