AS far as I know, they are all good products, and are pretty comparable.
I use
Power Service as that's what's added by local fuel distributors, and if I fill away from home, it will be comparable. White bottle is more for winterizing / anti-gelling, while Diesel Kleen (silver bottle) is more for warmer temps, keeping injectors clean and lubed, and injection pump lubed, and water dissipated all year.
There are other formulas for severely cold (arctic) operating temps, and 911 red bottle for fuel that's already gelling or gelled. If you go to any OTR truck stop, (any one I've been to lately) Power Service MASSIVELY outsells anything else.
SeaFoam is effective stuff in all of their products with a great reputation which is hard to earn and maintain. I know a LOT of people that use it and swear by it.
Rislone, Line of products such as Ring Seal, high mileage (motor honey) Compression Boost, Bars Leaks, etc, must be able to produce enough results against their claims to avoid false advertising claims. They've always, in my experience, been in the "if it sounds too good to be true, it probably is" realm of operation, but I doubt it would be harmful at least. It's most likely comparable to Marvelous Mysterious Mineral Spirits with Red Dye Additive, as they list most of the same "benefits".
Honestly I don't think any of them will hurt at any reasonable concentration/dilution ratios, even others such as Lucas, Stanadyne, or Liqui-Moly, but as you can probably tell, I would not rely too heavily on the Rislone.
EDIT - Sorry about all the edits. It's late. I'm tired.
