Is this for diesel pickups, or equipment using red dye? For my two diesel pickups, I have had good luck with plain old Diesel #1 in winter, down to -20F or a touch colder. Never had gelling issues with it in those temps. At -20F and colder, I put an additional additive in. Power Service Diesel is good but honestly I have had good luck with regular Seafoam too.

Oh no.
You're not running red dye in your on highway vehicles are you?
OP honestly you shouldn’t need much in the way of fuel treatment in your area. The temps just aren’t cold enough to be an issue. Low sulfur fuels are much more resistant to gelling than the older stuff. I live in Michigan and we just don’t see freeze ups like we did before low sulfur. Using fuel from a reputable station is the best bet.
If you are worried about water contamination powerserve products are good quality. That is what we use at the Mack Volvo Hino dealer I work at.
Do not over treat. Some of the filter medias do not like that. Use what the treatment manufacturer recommends.
Fuel treatments do absolutely nothing to increase mileage, add longevity to your fuel system, or any other wild claims some of them make. They are to disperse water and improve flow in low temps. Some are specialized and kill algae in your tank. Hope you never get that.
Just for fun there is no such thing as premium diesel. All # 2 and #1 fuel have cetane ratings they have to conform to. Winter blend may vary a bit depending where you are in the country.
The jist is (some details may need corrected) Diesel #1 is a winter blend, with anti gelling additives. Diesel #2 is a regular on highway diesel that most places sell in summer, in cold areas at least. Different states or even counties may require certain additives, for various reasons all year long.
Red dye (or 'high sulfer') diesel fuel is non taxed (where I am from anyhow) and only to be used in vehicles on non public roadways. That, plus tractors, generators, etc. I believe the sulfur levels were reduced for emissions reasons.
Refineries typically produce No. 2 in the summer, and a 'winter blend' in the winter. Some places cold enough just get No. 1.
Ted, Biggest thing is cloud point and gel point, No. 1 occurring at a lower temp.
A lot of diesel drivers like to add cetane improvers. You can think of cetane being analogous to gasoline octane. Higher cetane claims to improve starts and performance.
