Must really be expensive stuff. Redline puts it in a product that sells in a store for under $7.00. LOL
It appears by the Chevron web site that they invented PEA. They state they use it in their product Techron Concentrate Plus.
"Polybutene Amine (PBA) and Polyether Amine (PEA) are two chemical technologies originally developed and patented by Chevron to help clean harmful deposits from carburetors, injectors, valves, and ports. Although commonly found in most consumer fuel system treatments, PBA still leaves behind combustion chamber deposits, preventing an engine from being restored to its original performance.
Not only does Techron Concentrate Plus have enough PEA to help remove deposits from your fuel system in one tankful, but it also can clean and protect your fuel system sensors from sulfuric buildup – the root cause of faulty fuel gauge readings".
