The tendency of a hydrocarbon fuel, such as gasoline, to knock is measured by its octane number. Lower numbers denote a greater knock tendency; higher numbers denote greater knock control. "Knock" is an uncontrolled and explosive ignition of fuel in the combustion chamber. It causes a knocking or pinging sound, robs the engine of power and, left unchecked, causes serious engine damage. Knock may be eliminated with the appropriate octane number.
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

I'm not really sure of the performance increase by use, but I like what I read about what it is supposed to do and I trust Amsoil to deliver.
