Almost all of them say that. 99.9% of them are snake oil and the ones that do work, only increase mileage a tiny bit, mostly within noise error range.
If you engine is really loose, then yes, thick goo additive may improve compression and improve mileage but it is a bandaid.
I would love to see some additive that can take my 460 from a 11mpg gas guzzler to even 14 or 15mpg. The whole world would jump on something that gives improvements of double digit percentages.
If you actually do find an additive that improves mileage in a normal engine, please post it, we all want to know.
Meantime, tune it up, change oil and fluids. Make sure brakes are good and take all the excess junk out of the bed of the truck, inflate tires to proper pressure. Those will give you better mileage gains that most snake oils. Even a good wash and wax will help a tiny bit.
Good Luck,

PS. Woah. Just reread your post. 100 MPG??!!!! You need a long hill and disconnect the drive train, that will get you there. Otherwise ain't gonna happen with a truck so don't believe the hype of all the gizmo wizards out there.

An ICE is something like 30 percent efficient in a perfect world. I forget the exact figure because I took thermodynamics 35 years ago. Most of the energy in a gallon of gasoline or diesel is lost to heat in the exhaust and coolant. That is why turbocharging works. There have been experimental ceramic engines that hold in more of the heat and have less friction, but no one has come close to one that could be mass produced.
5W-20 oil with the current state of the art friction modifiers only deliver on the order of 1.5 percent gain over the old 10W-40 without FM's. Thats about as good as lubricant alone is going to get. Maybe 0W-5 ester-based racing oil can do better, but not if you expect your engine to last.

A gasoline engine, N/A will between 15-25% efficient, maybe even a bit higher for the latest stuff. Turbo diesels are usually around 30-35%, possibly higher once again for the newest ones.
The most efficient engine is a huge huge huge, 25,480 liter engine on a cargo ship. Its a two stroke turbo diesel, and it can reach levels of over 50% efficiency.

That is why I laugh at politicians who yell from the pulpit: "We need to raise gas mileage standards for all vehicles".
Translated: The working stiff car buyer will pay for it...
Modern vehicles now are straddled with regulations from the Feds and then some. Once a vehicle gets to be 8-10+ years old, 100,000 miles, things go wrong. the average owner cannot work on cars and trucks like they used to...
Now when things go wrong, a vehcile will shut down and quit. in the past, at least you could do some minor repairs to get to point "A" to point B"/.
I feel Ford Motor Company, and all US manufacturers as an industry, is doing a fine job in building new cars and trucks.
Soon, the Feds will expect Detroit to build a 1-ton dually truck that gets 45.9 MPG city then raise that standard to 55. 8 MPG. Never mind, weight, laws of physics, wind resistence ect/.
Too much is too much, and I feel sorry for Ford, GM and Chrysler when I hear some of our politicans speak.
