Preferred Customers pay the same low prices for AMSOIL products that AMSOIL Dealers pay.
Ten dollars gets you a six-month trial Preferred Customer membership for buying AMSOIL products at wholesale prices. Here is what Preferred Customers get:
Since the introduction of the world’s first synthetic motor oil, AMSOIL synthetic lubricants have been setting new standards for motor oil quality. They are specially designed to protect engine components, reduce emissions, last longer, reduce fuel consumption and prevent environmental pollution. From the beginning, AMSOIL synthetic motor oils have outperformed conventional petroleum motor oils on all counts.
AMSOIL INC. has been dedicated to helping reduce negative impacts on the environment. AMSOIL was the first to recommend 25,000-mile/one-year drain intervals. By safely extending drain intervals, AMSOIL synthetic lubricants dramatically cut the amount of oil consumed and emissions produced. This is not a new fad that AMSOIL is jumping on board with; it is the way AMSOIL has always operated.
In addition to the extended drain intervals, AMSOIL synthetic motor oils are specially designed to protect engine components, extending the life of the engine and reducing the need for replacing engine parts. They are also thermally stable with a strong resistance to high temperature volatility (burn-off), preventing sludge deposits and keeping engines clean. Low volatility and clean operation reduce oil consumption and emissions.
The advanced lubricity (slipperiness) of AMSOIL synthetic lubricants has also been proven to increase fuel economy. This reduces dependency on foreign oil and overall fuel consumption. The resulting improvement in fuel efficiency and reduction of emission levels contribute to the conservations of natural resources and protection of the atmosphere.
AMSOIL INC. doesn’t just leave the responsibilities of environmental protection to the products; the company itself is diligent in making efforts to keeping the earth clean. AMSOIL recycles virtually 100 percent of the corrugated trays and packaging boxes that come into its facilities, equaling several tons of recycled cardboard each month. All used steel drums and all “clean” plastic bottles are also recycled.
AMSOIL INC. is determined to continue to set the bar high for the lubrication industry across the board, including with regards to environmental responsibilities. Our long-standing quality products lead the way to a greener, healthier planet for all.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.
