it's probably just the stuff they pour into their gas to call it Chevron
Its very well known that PEA helps out - techronn gas and others have it in small amounts. Most bottled fuel additives have it in large amounts.

It is nice having the data to back up the claims. I am interested to see what the Top Tier Plus is going to do to help. My issue is I prefer ethanol free Top Tier and that is harder to come by.
Fuel additives can't clean the valves on a direct-injected motor so that part would only apply to hybrids

Wondering if something like Seafoam would do the trick?

Sadly most of the cleaners out there that I have seen tested really haven't done the trick very well with caked up intake valves in GDI engines. The best method is likely a walnut hull blast to get the valves cleaned up.
The trick would have to involve adding in another fuel rail with port injectors! Having to pay $500 to have the intake valves of a 3.2 Audi v6 walnut blasted was my welcome to a high mileage GDI engine. I have not owned another since, but that was also when I learned PEA and top tier fuel are not snake oil.

Sadly we have a lot of people stuck with GDI engines that the OEMs didn't see fit to correct the design to address the intake problems they created. It is pretty sad that OEMs are still dragging their feet on correcting this.

Luckily more manufacturers have been going to a dual GDI / port system, even though the intake problems don't usually start until well after the warranty.
It's a good reason to buy a hyrbid with a simple atkinson engine that doesn't have GDI, turbo(s), loosey goosey piston rings, and whole engine deactivation instead of cylinder deactivation.
Hasn't that proven to be false info? The new 2.0t is still direct injection-only IIRCIt can if you have the newer injection system with both port and direct.
Edit: I must have heard wrong, apparently it DOES have both

What is PEA ? Chemical name please.
I searched and folks talk about it but I didn't find what it is.
I also saw someone refer to "it" as PAO ??

Polyether amine (PEA) is a type of detergent additive used in fuel systems to clean and prevent the buildup of carbon deposits, especially in combustion chambers and injectors. It's known for its powerful cleaning action and can be found in various fuel additives and injector cleaners.
Personally I try to buy top tier fuel wherever possible, and use a bottle of techron in a tank of fuel that will mostly be used before an oil change.
The MY25 Ecoboost in the Maverick absolutely has both direct and port injection. It is not "false info;" it is well-documented around this site.
The name of the chemical was on the first page of Google results when I looked for "PEA fuel additive..."

PAO is an olefin that has nothing to do with PEA.
