Here’s a quick vid on fuel system treatments/ cleaners…
Amongst the many, only a few have PEA (Poly Ether Amine) which is touted as a strong detergent that cleans DGI related deposits. In my collection, Royal Purple has it.

The old Gumout (as shown in vid) use to have it, the new formulation is based on Ethanol. What happened?
If you guys know, pls chime in!
