but what about the FTE'r that sees that the ULSD lubricity properties are lacking and are considering a fuel additive as a maintenance item?
Maybe in this narrative, to much knowledge may be a bad thing. It’s hard to dismiss the fact that you can achieve long life for your 7.3, without any assistance from a fuel additive.
I read a paper posted online a couple years back regarding the cetane. The chemical that boosts the cetane (whatever it is) is what would make the average person's butt dyno say "wow, this makes my truck run better!" You will notice many of these fuel additives have a similar smell to them.
XPD is their flagship product which does a little bit of everything, but it is probably a waste of money in the summer since the anti-gel is not needed. They make a lubricity-only product "XL" as well as a cetane boosting product "Boost!" as well as a "Winter" and "Summer" branded bottle. I suspect there is quite a bit of overlap.
Edit: Optlubes handy little table comparing the products
Clearly I still have a lot to learn about additives in general, oil and fuel. I am merely a consumer attempting to lengthen the life of my 7.3L while maintaining a strict budget.
I had not seen that chart by Opti-Lube before, thanks for posting the link. I tend to look at a chart from a manufacturer with scrutiny though as the information can be biased. Although, if this is simply listing their products and their intended use, it seems to have some value.

I thought the used motor oil would do better but then again treating at a 200:1 ratio is hardly anything. If you dump a quart of ATF or used oil into a 26 gallon tank and fill it up you've got more like a 100:1 ratio. (I didn't see ATF on there though).
Everyone seems to agree XPD is one of the better ones. back when I filled my tank once a month I'd dump a dose of that stuff in and also dump a 4oz dose of Optilube "Boost" in there for good measure. That should have been good for an 8-10 point cetane rise the way I calculated. From what I read minimum pump cetane has to be at least 40 and ideal is closer to 60, so figured that should have been enough to turn a mediocre tank of fuel into a passable one, and a passable one into a very good one. Nowadays it's not uncommon to fill up 3 times a week so that would all become a little cost prohibitive.
There are some good findings in the chart that I would liked to have seen years ago when I was still running the Stanadyne Lubricity. At least Stanadyne was not down there with "Primrose and Marvel". Just like the PQIA analysis listing, we are only subject to the additives that have been analyzed.

Keep those fuel filters clean!
Could be and you bring a valid point. Just like too many choices can be a bad at times. Again, you are 100% right in that you have first hand knowledge of a long life 7.3L without any fuel additives. This is great information that can/should be evaluated and added to the library of consideration points by a consumer.
I believe the Phillips 66 cogen plant in Linden, NJ is only major refinery on the east coast.
I don't even know what's left around here any more. When I was a youngster I used to hit a lot of the local refineries for the job I had and there were a heap of them. I was young and figured the whole country was loaded with them, little did I know that we just had dibs on them. ARCO, Gulf and Citgo right in or around Philthytown, Sunoco and BP to the south, Texaco at Eagle Point, NJ, right across the river. Something down in DE, I believe Valero is down there now. And there is stuff up in north Joisey but I don't know what it is. Most of them have been bought out by rivals, burnt down or just closed up.
Finlander, the last sentence which states "The product contains additive, which improves storage stability, lubricity and conductivity" in addition to the HFRR rating in the third to last row shows me you do NOT need to use a lubricity additive in your fuel.
At a HFRR rating of "350", your fuel is not quite as good (lubricity wise) as our bio-diesel blends, but puts your fuel squarely between #2 and #3 in the 2007 study. Again, the study was conducted on ULSD available here in the United States after the EPA went to the ULSD mandate in 2006. Since then, the ULSD blend of fuel has not changed in any significant way.
Therefore, we can assume that the 2007 study is still relevant and pertinent to the discussion of lubricity additives.
Although, @KubotaOrange76 brings up a good point (in jest of course)... Without seeing any testing, 2021 HFRR ratings for example, on "bacon grease" and whether or not that is "filtered or unfiltered", I can say with any sort of confidence where Bacon-Diesel (closest color to bacon I could find) would rate on the list. In addition, even if the bacon grease is filtered, how do you stop it from clogging the screen of the fuel pump, sending unit or filter bowl filter itself? This seems like it could warrant another thread, which may actually be somewhat of a new discussion and approved by the peanut gallery, but I would have to verify this before committing to that statement.
Perhaps search for thread titles with Bacon Brah, ULSD (Ultra Low SIZZLE Diesel), Where did my bacon go brah?, damn that shizzle smells good brah!
Im going to take the bacon grease from tomorrow and pour from pan into my tank. I will tell my boss to stop using the xdp i recommended in his 6.7 and go to bacon grease, he will be double happy cause he just started keto.
He lost his fuel system around 210k to maybe a "bad load" of fuel from high volume gas station.
Hot Shots is not on the list the OP started with.
I used Power Service Diesel Kleen in the 7.3, read some interesting info (can't find it now) about Hot Shots EDT (Everyday Diesel Treatment) and have been using it in the 6.7.
From what I remember, across the board Hot Shots was rated 1st or 2nd on the following - Lubricity, Cetane boost, Cleans injectors, Rust preventative, Demulsifies water, Fuel Stabilizer for storage. No other product was that consistent.

Reason: Spelling
Found this test on youtube for anti gelling but also tested for other things including corrosion and scarring too. Optilube was not included in this test but it was interesting.
All you folk burning your bacon grease in your 7.3s are speaking heresy. That grease is precious and should be saved for deep-frying other stuff in. Same applies to beef tallow. Tsk tsk.
From what I gather, Hot Shots makes some nice products, but that is only based on what I have seen via YouTube and from sources on the FTE. In my uneducated and layman opinion, I plan to research additives a bit more prior to traveling the country again with the truck and trailer, hopefully next summer if things calm down a bit.
Like Mark I too am...

Brah, here in the south there is plenty of bacon for our DEEZEL and our BELLIES! Besides BillyBob said on the FACEF**K that bacon grease is good for LED headlights and gives a MST 1,000 HP at 500* EGT towing 40,000 lbs based on butt-dyno results!
