If you plan on keeping a diesel beyond the warranty period I would use a lube. Do a little a little research on fuel lubricity-SCAR rating- for here in the USA and over in Europe. Our fuel doesn’t lubricate as well. HPFP will fail prematurely on US diesel but it will likely be beyond the warranty period, hence Ford is not concerned about the design flaw.

Just be advised, opti-lube is not an emulsifier , so water will stay in form and you would be relying on your water separator to collect it and alert you so you can drain it.
thefirst question folks ask when they get told you need a new fuel system due to water contamination is “ why didn’t my water separator contain the fuel and why didn’t the computer alert me that I have water in my fuel system?

Cummins guys have been running ashless 2 stroke oil for years. Walmart sell it by the gallon super cheap. However, the single best lube you can use is bio diesel.but its not always available and isn't so great in super cold weather✌

I been using Archoil for years with no complaints. Never get water when I drain fuel filter between changes and it actually picked up a little over a mile per gallon on mpg. I have no reason not to use it.

That’s why you use a demulsifier. In any case, I think water gets blamed when the real cause is lack of lubricity.

Nope, not a waste of money unless you prefer to replace your HPFP down the road

Optilube and other demulsifiers help separate the water from the diesel even more. . All the owner has to do is drain it.
I drain mine at least once a month.
Emulsifiers on the other hand typically contain alcohol and are no no

The separator is designed to separate water from diesel.

my lack of confidence is probably related to the questionable efficiency of the water seperators and the questionable alert that you have water in your seperators and the fact that I have never drained any water from any of the 3 trucks that had seperators.
the good news is that the 2020 model will have a new design seperator...maybe that one will a tuLly work.
