AMSOIL's History

Pilot Al

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 that these same benefits would prove invaluable in combustion engines, Al 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, AL continued his research and development and sold commercially available synthetic oils under a variety of names.

In 1970 he incorporated his name into a commercially sold product he called AMMOIL (the name came from a nickname he had in the air force, “Ammo”). After a while, many started referring to the oil simply as AM’S OIL.

In 1971, the name was changed to AMZOIL and it continued to be sold commercially. The name would later be changed to today’s familiar AMSOIL.

First-Oil-Can-1972

The true milestone came in 1972 when AMZOIL 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 (API) service requirements for automobile engines.

It signaled a new age in lubrication science and the birth of an entirely new industry.

The new lubricant performed like no other had before. 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 AMSOIL’s lead with introductions of synthetic motor oils of their own.

Quality First

AMSOIL Lab

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 Lubricants.

Research & Validation

Reseach & Validation

AMSOIL invests heavily in product research and validation to ensure we remain at the industry’s forefront. Research and testing are one of our highest priorities at AMSOIL.

The company’s research and development facilities are staffed by specialists in every facet of synthetic lubricant technology.

Our on-site chemical and mechanical test facilities contain the sophisticated analytical instruments needed to develop cutting-edge synthetic technology.

Quality assurance test procedures are rigorous and begin with analysis of every raw material that enters the plant.

Both during new product development and as a continuing control on the manufacturing process, our AMSOIL lubricants are subjected to an exhaustive series of standardized industry tests, including those that measure film and shear strength, flashpoint, volatility and high- and low-temperature viscosity.

No other lubricant manufacturer in the world matches the high-quality standards set by AMSOIL, and all AMSOIL Synthetic Lubricants exceed the industry’s most stringent specifications by a wide margin.

Field Testing

Even the most comprehensive lab testing must be validated in the field. AMSOIL products are proven in intensive field demonstrations involving automobiles, trucks, powersports, off-road vehicles, commercial and industrial equipment, and many more, in real-world service situations.

Some of our long-range studies have involved vehicles requiring the most severe lubricant applications: taxicabs, delivery fleets, police and emergency vehicles, over-the-road trucks, wind turbines, heavy-duty construction and industrial machinery, and more.

AMSOIL Synthetic Products for Fleets.

Results of tests performed under these extreme operating conditions demonstrate that AMSOIL products reduce engine wear, decrease maintenance time, maximize fuel efficiency and increase fleet cost effectiveness.

The final, conclusive proof of any lubrication product is, of course, the superior performance acknowledged by satisfied consumers and cost-conscious fleet managers.

Racing is Research

Further testing occurs at racetracks around the world. AMSOIL Lubricants have helped racing teams operating off-road trucks, stock cars, modified vehicles, monster trucks, high-powered boats, dirt bikes and snowmobiles capture countless checkered flags and championships.

Racing is Research. AMSOIL full synthetic lubricants for race cars and trucks, boats, off-road vehicles, ATVs, snowmobiles and more.

“We purchased the AMSOIL Center in the fall of 2004 in order to expand our production and warehousing capabilities.

We installed the industry’s most advanced packaging lines, increasing production capabilities by 250 percent. We installed the industry’s most advanced blending equipment, increasing efficiency and maintaining the high level of quality demanded of AMSOIL lubricants.

We constructed a new laboratory, ensuring only the most high-quality formulations emerge. The world’s best raw materials are delivered here, and the world’s best lubricants are housed here.

Achieving a high level of success is not easy. It takes hard work, dedication, persistence and a little help. This is true for any type of business. I worked very hard to develop AMSOIL synthetic motor oil throughout the 1960s. I worked even harder to get it API-certified in 1972, but it took a little help from the AMSOIL Dealer network to make AMSOIL the success it is today.

The AMSOIL Center is the result of the hard work and dedication of many. I started producing AMSOIL synthetic motor oils out of a tiny garage here in Superior, Wis. Now, the AMSOIL Center is more than nine acres under one roof. I used to blend and package AMSOIL motor oils myself. Now, the AMSOIL Center boasts the finest state of- the-art, automated packaging equipment in the industry.”
