Just trying to find one of the P.E.A containing fuel injector additives - but obviously value depends on how much of the good stuff they put in the additive - as many seem to have only a tiny amount:
Caltex Techron Concentrate contains 15-20% Polyether amine
Rislone Hy-per only as 0.1-1%! Seems very dodgy as they openly state that it contains P.E.A but has very little of it!
A well regarded US one Regane Gumout has 10-30%
The STP one is very confusing, seems to have a bunch of stuff but no pure PEA but some similar ones.
If you can find it Red Lineยฎ SI-1 Complete Fuel System Cleaner has apparently the highest at 28-34%.
Annoying that a lot of ones seem to either have a very small amount - which would have likely no benefit or seem to use very tricky names which make it unclear if they have it at all.
Amazing when you look at the SDS that so many of them are very questionable in benefit i.e all kerosene or napha etc. All the Australian brands were really shitty when you looked into them - Penrite, Nulon etc very low levels of PEA.
PS. FWIW the best value by far was the Redline SI-1, contains 28-34% PEA - so you could use much less of it for same effect. This was the cheapest i found for a single bottle:
