In 1972, AMSOIL INC. introduced AMSOIL Synthetic 10W-40 Motor Oil and became the first company in the world to manufacture and market an American Petroleum Institute (API) rated synthetic motor oil.
Why synthetic? Because synthetic lubricants are superior to conventional petroleum lubricants. Petroleum lubes are refined from crude oil, a natural substance pumped from the earth and containing diverse chemicals. Some of the chemicals in petroleum oil are detrimental to the lubrication process and to the lubricated components. For example, some petroleum oil chemicals invite oxidation in high temperature operations. Oxidation quickly destroys lubricant integrity.
Synthetic lubes, on the other hand, are not refined from crude oil, but constructed from pure chemicals selected for their ability to lubricate. The purity of synthetic lubricant basestocks significantly reduces lubricant oxidation, which promotes the ability of synthetics to be used in higher temperature applications than conventional lubes may be and promotes their ability to be used for extended drain intervals. In fact, AMSOIL synthetic lubricants are specially formulated for extended drain intervals.
Synthetics are also free of the paraffins found in conventional petroleum oils. With no paraffin to congeal at low temperatures, synthetics maintain better low temperature fluidity than petroleum oils do, which protects equipment operating in cold environments -- even the relative cold of a just-started engine.
The molecular uniformity of carefully selected synthetic lubes promotes superior lubrication and friction reduction, which in turn promotes superior heat control, wear control and energy efficiency. Molecular uniformity also helps synthetics maintain their protective viscosity in high temperature operations, which also promotes superior wear control.
The superior performance and protection afforded your equipment by AMSOIL synthetic lubricants adds up to increased productive time and profits for you.

Gasoline Engine Oils -- AMSOIL offers a wide range of gasoline engine oils. The preferred oil for stationary gasoline engines is AMSOIL Synthetic 10W-30.
By-Pass Oil Filters -- AMSOIL offers by-pass oil filters in single or dual filter element configurations for use in diesel or gasoline mobile or stationary engines. By-pass oil filters subject oil to ultra-fine filtration, removing particles smaller than those typically captured by conventional oil filters. AMSOIL by-pass oil filters also remove water from circulation, something conventional oil filters cannot do.
AMSOIL by-pass oil filtration systems also call for the addition of oil to the engine's sump. The larger than typical volume of oil afforded by the by-pass "spreads the load" better, so each quart rests longer, cools more, stays cleaner and lasts longer.
The AMSOIL Dual Gard By-Pass Oil Filtration System allows mounting of two by-pass filter elements, which allows even more oil in the system and doubles by-pass filter element change intervals.
Automatic Transmission Fluid -- AMSOIL Synthetic Automatic Transmission Fluid (ATF) is formulated for passenger car automatic transmissions, power steering units and hydraulic or compressor systems calling for ATF.
AMSOIL Synthetic ATF offers superior performance over a greater temperature range than conventional ATFs do, allowing free fluid flow through narrow transmission passageways in cold temperatures and resisting high temperature thickening, sludging and deposit formation in high temperatures.
