Stanadyne is OK. The Ford formulas are OK. Beyond that I'm not sure.
I don't use anything often, although I have used Stanadyne and never noticed any difference whatsoever. I think it's good practice to use Stanadyne cleaner every so often, but haven't done that yet.

You don't want to emulsify water in the fuel on modern high pressure diesels because that causes the water to go through the fuel filter/water separator to the engine.
That's bad.
You want to demulsify the water in the fuel so you can block it and drain it before it hits the injectors.

I have always used Stanadyne performance formula. It is a quality product made by a large fuel injector manufacturer. Year round, every fill. I have used it since 2006.
Lubricity is one big issue, stiction another and water in fuel a third.
It helps with all this plus has a cetane improver. Might have been fine without it, but when I first started using it on the Ford 6.2, the difference in the actual sound of the engine was amazing...I was sold. Smoother and quieter.
Don't forget to drain your fuel/water separator monthly. Document it.

Keep in mind, when the engine starts cold, pilot injection is not running initially. When its warm outside, the delay between engine start and pilot injection starting might be seconds. When it is cold outside, that delay might be several minutes. When pilot injection is not running, the diesel engine will sound much rougher with all the fun sounds normally associated with an older diesel.

Exactly. Read the PSPs for Power Service. It is primarily alcohols & petroleum derivatives that are, in fact, emulsifiers. The letter from Power Service quoted above is largely smoke & mirrors/word manipulation. There is a certain amount of water than can be emulsified in a given volume of diesel fuel. Any more than that will naturally be “demulsified”, or precipitated out. That’s 8th grade science class.

You're running Stanadyne in the gas engine?

When it is cold outside, that delay might be several minutes.

I order mine at the dealership as they generally don't stock them. Here's a link to Amazon. https://www.amazon.com/Ford-PM-23-GA.../dp/B001H1OGMY
