Don't know which one has more PEA, Critic says the HM, ok with me.
But, contrary to the above opinion about not using Regane, I've found the regular Gumout Regane to be both an effective and reasonably price product in my vehicles.
Documentation of pea or not, I'll continue to use Gumout Regane with confidence, quality product. And Regane afaik is not designed as a UCL, so reference comparison is extraneous.
