AMSOIL is "The First in Synthetics" and also the first in 
quality, protection and performance.

AMSOIL is the only company in the world to own trademark rights to 
"The First in Synthetics"

Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and has followed the AMSOIL lead by introductions of synthetic motor oils of their own although mostly are not 100% pure synthetic like AMSOIL is; they are Group III Hydroisomerized petroleum oils, marketed as synthetics under a new law. They spend millions of dollars advertising their "new" and "revolutionary" products. No one, however, can match AMSOIL experience and technological know-how. And no company in the world delivers products like AMSOIL.

Petroleum motor oil's film strength is about 400 psi where as AMSOIL lubricants film strength is about 3300 psi and does not break down, shear or loose viscosity under heat and stress. Petroleum motor oil breaks down under heat and stress and leaves carbon, varnish and sludge deposits in the engine and allows critical engine components to wear much more rapidly.
