According to wikipedia, Chevron was the first to introduce PEA additives to their gasoline.
If PEA additive is not the best, what other additive is better than PEA that can clean deposits efficiently and not leave behind residue?
I am not claiming to be an expert. I am also here to learn.
From reading the information on most forums, PEA additive is what people want.
@ y_p_w, you stated PEA is not being used as a detergent. Can you explain?
The primary chemical uses of PEA are for curing plastics and paints. It's a broad category that includes a lot of chemicals that won't be useful as fuel detergents.
Some of the literature on PEA use indicates that some types are in fuel additives for uses other than as a detergent.
And there are certainly PEAs used in additives other than from Chevron. This is from Afton, although it's marketed as an aftermarket fuel treatment and not specifically for pump fuel.

HiTEC® 6406 is formulated with Afton Chemical's high purity polyetheramine detergent and is compatible in high ethanol fuels.
As for the use of PEA in detergents, here's just one patent by Lubrizol that mentions the use of PEA detergents.

What I'm trying to get across might be summed up by the adage "There's more than one way to skin a cat." PEA is very good as a detergent, but I'd worry far more about how well an overall additive package works. There's no particular reason why a detergent additive package has to include PEA to achieve maximum effectiveness. Like many things, it might be possible to simply use more of something else to be equally effective.
