ROWLAN SYNTHETICS Authorized Independent AMSOIL Dealers


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 their extraordinary ability to reduce friction and wear on engine components, function dependably at severe temperature extremes and withstand rigorous and lengthy engine operation without chemical breakdown.

Recognizing these same benefits would prove invaluable in combustion engines, Amatuzio began conducting serious research in the early 1960s. He soon developed and sold commercially available synthetic oils under a variety of names. The true milestone came in 1972 when AMSOIL became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. It set all-new standards for motor oil quality and outperformed conventional petroleum motor oils on all counts. It was clear from the start this innovative product would play a major role in redefining the performance capabilities of modern machinery and engines.

Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and has followed the AMSOIL lead with introductions of synthetic motor oils of their own. Accept no substitutes – AMSOIL is The First in Synthetics®.

Facilities -

The AMSOIL Corporate Headquarters, Manufacturing Plants, and Main Distribution Center are located in Superior, Wisconsin, with several regional warehouses strategically located throughout North America and overseas.  These facilities cover a total of 700,00 square feet.

The state-of-the-art lubrication production plant contains materials blending and bulk storage facilities, as well as high speed bottling lines and packaging equipment.  The main warehouse serves as the hub of a global distribution network; bottles, cases, drums and totes bearing the AMSOIL label are shipped worldwide.  Capacity is geared to meet projected market demands decades away.

Products -

AMSOIL formulates a wide selection of synthetic lubricating oils for all types of engine and gear applications, including those for specialized vehicles and severe operating conditions.  In addition, AMSOIL has developed sophisticated fuel additives, filtration systems and other companion products that supplement and extend lubricant performance.  All are distributed through a worldwide network of Independent Dealers.

This complete line of quality products is recognized by countless private motorists, fleet managers and industrial administrators as the best and most cost-effective choice for increasing engine performance, reducing maintenance and prolonging vehicle and equipment life.

Environmental Impact -

As our world strengthens its environmental policies and grapples with pollution issues, the ecological wisdom of using synthetic lubricants becomes obvious.  AMSOIL synthetic motor oils outlast regular petroleum-based oils by as much as 11 times. These remarkably long drain intervals help ease the world’s waste-disposal problems: users of synthetics simply have much less oil and fewer plastic containers to deal with.  The combined use of AMSOIL motor oil, AMSOIL Ea Air and Oil Filters and engine oil analysis greatly extends oil change intervals.

The superior lubricity of AMSOIL products means much less friction, drag and wear on critical engine parts.  The resulting improvement in fuel efficiency and reduction of emission levels contribute to the conservation of natural resources and protection of the atmosphere.

AMSOIL INC. Is determined to meet the challenge of the lubrication industry’s environmental responsibilities head on.  The company’s long-standing quality products lead the way to a greener, healthier planet for the next generation.

AMSOIL has been the leader in quality synthetic lubrication for over three decades, and will continue to introduce dynamic and innovative products to meet the challenges of the 21st century.
