 The World's Best Synthetic Lubricants From AMSOIL 




AMSOIL specializes in developing synthetic lubricants that offer innovative answers to the greatest challenges vehicles and equipment present. The extraordinary performance of AMSOIL synthetic lubricants in a range of markets – automotive, powersports, industrial, racing and more – have made our influence in the industry unmistakable and our brand highly respected. Our commitment to innovation has resulted in legions of brand-loyal customers.




AMSOIL President and CEO Al Amatuzio founded his company on the same principles that defined his career as a jet fighter squadron commander – excellence, integrity and strong leadership. In 1972, the breakthrough came. AMSOIL 10W-40 Synthetic Motor Oil, the result of years of research and inspired by aerospace technology, became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. It outperformed conventional oils on all counts, signaling a new age in lubrication science. Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and followed the AMSOIL lead with introductions of synthetic motor oils of their own. Accept no substitutes – AMSOIL is The First in Synthetics®.


In 1994 Al Amatuzio was honored as the pioneer of synthetic lubrication with his induction into the Lubricants World Hall of Fame.




AMSOIL invests heavily in product research and validation to ensure we remain at the industry’s forefront. Our on-site chemical and mechanical test facilities contain the sophisticated instruments needed to develop cutting-edge synthetic technology. AMSOIL synthetic lubricants are validated in long-range studies with taxicabs, delivery fleets, police and emergency vehicles, over-the-road trucks, wind turbines and industrial machinery.


Further testing occurs at race tracks around the world. AMSOIL lubricants have helped racing teams operating off-road trucks, stock cars, high-powered boats, dirt bikes and snowmobiles capture countless checkered flags and championships. We believe that Racing is Research™, and we use the data our racing efforts generate to tailor AMSOIL formulations for even greater levels of performance and protection.




AMSOIL is firmly established as a leader in synthetic lubrication. The company's history is a checklist of industry firsts, and its legacy of research and innovation continues today.



Holding ourselves to higher quality standards is our industry trademark. We select raw materials based on quality and performance, not price. Each chemical is tested to ensure it meets our quality standards before it is accepted into our manufacturing facility. Our manufacturing process uses a strictly controlled computerized process to maintain top-quality finished products. Samples of the finished product are subjected to a series of industry-standard tests prior to packaging. Every product AMSOIL manufactures is tested every time it is blended to ensure maximum quality and consistency, ensuring AMSOIL customers receive the same high performance every time they purchase AMSOIL synthetic lubricants.



AMSOIL believes that developing products to enrich the lives of our customers is more important than maximizing profits. As a family owned company that isn’t beholden to stockholder demands, we maintain the freedom and flexibility to make business decisions that support that philosophy. We remain loyal to those who use our products, and we strive to run our company in a way that benefits them.



AMSOIL INC. embodies the American ideals of entrepreneurship, innovation and hard work. President and CEO Al Amatuzio’s initial idea half a century ago has grown into a company recognized as a world leader in synthetic lubricant technology. Despite the opportunity to save money by manufacturing in other countries, we’re committed to formulating, blending and packaging AMSOIL synthetic lubricants in the United States.



AMSOIL makes top-quality synthetic lubricants for your car, truck, motorcycle, boat, four-wheeler, snowmobile, lawnmower and anything else with an engine. AMSOIL lubricants are designed to help your equipment run at peak efficiency and last longer. Join the millions of proud AMSOIL users to experience the difference.



AMSOIL's 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 more than 300,000 square feet. The recently expanded and modernized lubricant production plant contains materials blending and bulk storage facilities, as well as high speed canning lines and packaging equipment. A separate plant is thoroughly equipped with specialized tools and machinery for the manufacture of AMSOIL's various air and oil filters. The main warehouse, newly enlarged to a storage capacity of 60,000 square feet, serves as the hub of a global distribution network; bottles, cases, and drums bearing AMSOIL are shipped worldwide. Capacity is geared to meet projected market demands a decade away.


All of AMSOIL's administrative functions are centrally located at its own downtown building, substantially renovated and outfitted with the latest in communications and information processing equipment. The entire complex is staffed by a cooperative, knowledgeable, and well disciplined team of over one hundred employees. AMSOIL's professionals are ready, willing, and able.




Our research and development facilities are staffed by specialists in every facet of synthetic lubricant technology. The chemical and engine test laboratories are well equipped with the sensitive analytical instruments needed for design and development of the world's finest oils.

Quality assurance test procedures are rigorous, and begin with analysis of every single barrel of raw materials that enters the plant. Both during new product development as a continuing control on the manufacturing process, AMSOIL lubricants are subjected to an exhaustive series of standardized tests, including those that measure film and shear strength, flashpoint, volitility, and high and low temperature viscosity.

No other lubricant manufacturer in the world matches the high quality standards set by AMSOIL, and all of AMSOIL's synthetic lubricants exceed industry specifications by a wide margin. Our 100% American made products pass even Europe's more stringent tests with "flying colors".



Even the most comprehensive lab testing must be validated in the field. AMSOIL products are proven in intensive field demonstrations involving automobiles, trucks, and commercial and industrial equipment in real world service situations. Long range studies have involved vehicles requiring the most severe lubricant applications: taxicabs, delivery fleets, police and emergency vehicles, over the road transports, and heavy duty construction and industrial machinery.


Results of tests performed under these extreme operating conditions demonstrate most emphatically that AMSOIL products reduce engine wear, decrease maintenance time, maximize fuel efficiency, and increase fleet cost effectiveness. The final, conclusion proof of any lubrication product is, of course, the superior performance acknowledged by satisfied consumers and cost conscious fleet managers.



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 eight times. These remarkable long drain intervals help ease the world's waste disposal problem: users of synthetics simply have much less oil and fewer plastic containers to deal with. The combined use of AMSOIL motor oil, air and oil filters, and engine oil analysis has now made one fill, zero waste lubrication a reality.


The superior lubricity of AMSOIL products means 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. Additionally, AMSOIL has made the technology of biodegradability a top research priority, with encouraging recent successes.


AMSOIL INC. is determined to meet the challenge of the lubrication industry's environmental responsibilities head on. Our long standing quality products lead the way to a greener, healthier planet for the next generation.



OUR WORLD RELIES ON TECHNOLOGY meet ever increasing demands of transportation, manufacturing, and industry. The use of high quality synthetic lubricants to meet these demands has grown steadily. However, tomorrow's needs will be different from today's. AMSOIL INC. anticipates these needs and will remain on the leading edge of new developments.


As engineering and automotive technologies progress and generate higher performance machinery, it is certain that synthetic lubrication will be the ONLY choice for many applications.

AMSOIL's Commitment To Excellenceassures that we will set the standards by which other lubricants will be judged.


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