Most PEA Bang For Your Buck

Don't put words in my mouth. I indicated it was a last resort, because there are lots of people who have gotten significant mileage gains with PEA additives, like 1-3 mpg depending on many factors, of course. Of course I don't expect magic for $15, but it is certainly worth the experiment.
Imho, those injector cleaners are about that, they will dissolve some gum in fuel tank, lines and injectors thus helping with better and less restricted fuel delivery and injection allowing for better ignitability and fuller burn after cleaning. Additive itself will also dilute fuel to potentially reduce gas mileage just a smidge while going thru that tank.
I run Gumout Regane Complete bought in US WM and usually on about 1/2 full tank; and basically just to keep injectors unclogged and spraying as they should.

I've used Redline Complete Fuel System Cleaner for my PEA cleaning for years. Serves me well every six months.
correct on both counts. the 3.5/3.7 use the same block, only difference is bore size. and yes, the RWD variants have a proper external pump.
Your intention insulates it. You should already know that there are infinite variables when it comes to fuel economy. There is no way you can pin point the problem and assume it need additives just to improve you MPG's. Not only that - how many bottles do you need to use just to improve your fuel economy? Will justify the amount of money you put into the additives be cheaper in the long run? How many bottles will be used? I understand it can be used as a maintenance protocol such as other preventative maintenances. And just because it works for other vehicles does not necessarily will work for your vehicle (even if it's the same year, make, model, engine size and etc.. due to variabilities of the circumstances). We do not live in the same area, climate, altitude, etc, etc.. We don't take the same route nor drive the same driving conditions.
I use redline every 5K in the Tundra. It sees top tier fuel every time. The Pilot get 2 bottles at 60% and 20% olm. It gets top tier every so often.
Just to restate my previous post, Ford does not want a check engine light unless absolutely necessary. To that end, the ECU is programmed to compensate to maintain emissions compliance. Lazy O2 sensors and other sensors can contribute to low MPG while not showing up during a scan.
I am not going to insist that's what is wrong. I don't know your vehicle. But please don't be under the impression that since there is no code, everything is optimally functional.
Try my idea of non ethanol fuel and report back.

I like your thoughtful, measured response. Heck, I might try it. Will let you and the thread know what happens if I do so.
To the OP, if the drive train is up to spec, turn your attention to the wheel bearings, brakes, Tires and tire pressure, and Alignment (as another poster mentioned). Also record your own observed mileage and compare to the Lincoln's built in calculations. With two of my vehicles (both Nissans) one is almost dead on, the other is off by up 4 mpg at times. With all this said....and every other comment, something is seriously out of wack to be down 16+ MPG.

Your numbers for percent of PEA is far greater than what any of them claim on the SDS's. And for the sake of simplicity and comparing apples to apples, my pricing was from one source.

25k miles is really infrequent, almost not worth the bother. Personally I think every 10k would be more like it.

Agreed, if those numbers were that high they would surely be published as such in the SDS.
Very optimistic for sure
You need to be careful where you pull these. There's lots of old versions, old revisions of MSDS floating around the web.
These are directly from the respective manufacturers websites as of today:

Yes, I realize that there is a lot of varying facts for the same product on the various MSDS's and SDS's. As you say, still floating around, nothing dies on the internet. I don't know if you looked at the one for the Techron High Mileage. On the SDS that I saw and used, it had a nice narrow range of 20-25% "Trade secret." That's why I used 22.5% for my OP analysis.
Coincidentally with all this, the local Advance has a BOGO on the Techron products, $12.99 for two, so I bought six.
Perhaps I'm overestimating the performance of top tier fuels.
