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. 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.

So, what is it that allows AMSOIL motor oils to be used for extended drain intervals, while other oils must be changed significantly sooner? First, the synthetic base stocks with which AMSOIL motor oils are formulated are worlds apart in quality compared with conventional base stocks. The synthetic molecules are uniform in size and shape, resisting the vaporization that boils off the smaller molecules of conventional motor oils and leaves behind a thicker, higher viscosity oil that compromises engine protection. AMSOIL motor oils surpass even the most stringent European volatility standards, providing superior protection for extended drain intervals.

Second, AMSOIL spares no expense when it comes to additives, selecting the most robust additive packages on the market. These additives keep AMSOIL motor oils shear stable, resist the degrading effects of varnish and sludge, keep engine components clean and deposit-free and effectively resist rust, corrosion and foaming.

By using only the highest quality synthetic base stocks and additives available, AMSOIL motor oils are capable of extended drain intervals, all while maintaining performance, providing long-term wear protection and fuel economy, keeping engines clean and deposit-free, providing cold weather starts and protecting against rust and corrosion.


Though AMSOIL Inc. was founded in 1972, its story begins in the mid 1960s, when Lt. Col. A.J. "Al" Amatuzio, a jet fighter squadron commander, was impressed by the superb performance of synthetic lubricants in jet engines (in fact, only synthetics stand up to the performance demands of jet engines) and began studying their possible automotive applications. In 1972, after an intense period of research and development, Al Amatuzio introduced the firstsynthetic motor oil in the world to exceed API automobile service requirements.

The next year, Amatuzio developed a marketing plan to get his innovative but still unknown product to customers. His marketing plan enabled customers to have personal contact with a Dealer who could take the time to explain the product and answer questions. The rest is history! From humble beginnings in a northwest Wisconsin warehouse, AMSOIL pioneered an entire industry -- synthetic lubrication -- and established high professional and ethical standards for a unique business opportunity.

Since 1972, the company has seen rapid growth and constant change. One driving force behind the great success of AMSOIL is a commitment to quality and constant improvement. As the years passed, an increasingly broad range of automotive and industrial lubricants and filtration equipment was developed, with each new product exceeding industry performance specifications by a wide margin.

AMSOIL offers a great selection of products for your vehicle.


AMSOIL Premium synthetic drivetrain lubricants reduce wear, extend service life and maximize fuel economy.

Synthetic Transmission Fluids
AMSOIL synthetic transmission fluids withstand the rigors of high-torque, heavily loaded tractors and other equipment. They maintain viscosity for reduced gear and bearing wear, helping increase equipment life. Their synthetic formulations resist oxidation, varnish formation and sludge build-up to provide superior cooling and protection. Their synthetic chemistries maximize fuel efficiency and provide up to 500,000 mile drain intervals in OTR trucks with manual tranmsisions.

Synthetic Gear Lubes
AMSOIL synthetic gear lubes feature naturally high film strength and premium additives that help shield gears from metal-to-metal contact for maximum wear control. Their low-friction formulations promote increased fuel efficiency and are designed to provide long oil, seal and equipment life. AMSOIL 75W-90 Long Life Synthetic Gear Lube provides outstanding protection throughout drain intervals of up to 500,000
miles in OTR trucks.

Synthetic Greases
AMSOIL synthetic greases are engineered to remain in place better than
conventional greases to provide reliable protection. They feature exceptional adhesion properties and superior friction-reduction abilities for long equipment life.

Synthetic Hydraulic/Transmission Oil
AMSOIL Synthetic Tractor Hydraulic/Transmission Oil is sufficiently robust to protect heavily loaded transmissions and certain wet-brake ATV differentials, yet flows readily to provide dependable, smooth operation in hydraulic systems. Its all-weather formulation reduces the need for seasonal oil changes by resisting high-temperature breakdown during long summer hours and by remaining fluid in sub-zero winter conditions. Synthetic Tractor Hydraulic/Transmission Oil resists corrosion, limits wear and promotes increased energy efficiency.
Qualifies as a Universal Tractor Transmission Oil (UTTO)

Synthetic Hydraulic Fluids
Superior synthetic hydraulic fluids provide outstanding all-season performance. Increased Protection AMSOIL synthetic hydraulic fluids are formulated to resist high-temperature breakdown, helping to keep hoses, valves and pumps clean and operating properly. They remain fluid in sub-zero temperatures to limit pressure spikes, unresponsiveness and other problems inherent to inferior fluids. AMSOIL synthetic hydraulic fluids are designed to withstand the stresses of high-load, high-pressure operation and inhibit foam, corrosion and deposits for long equipment life.

AMSOIL Synthetic Anti-Wear Hydraulic Oil contains anti-wear additives and rust inhibitors to provide optimum protection for expensive equipment.
