Prist is an additive to fuel that keeps ice from building in fuel lines. Somtimes fuel contains water that you cant see. When the plane climbs the temperature drops and the fuel cannot hold water. This water can separate out and could be a bad thing if it freezes in fuel lines blocking the flow of fuel and then there goes your engine.

Prist is also Anti-microbial agent. Therefore it helps to keep sludge from forming in the fuel systems. This is important if the airplane rarely flys. We fly our aircraft Mon-Fri, so it is not sitting for very long, so we very seldom add it. Many times it is already pre-mixed, so it is not an option.

It is also a anti-microbial agent; it kills the little organisms that grown in jet fuel. It is not longer labeled as such because the manufacturers of prist did not want to do the studies to meet FDA approval for such a label.
