You don't need any anti-gel if you are buying fuel in the region where those temperatures are normal/expected. Winter fuel is treated for the area.
There are exceptions, but they're rare.
Once in Denver, all the diesels gelled up about 10 years ago. Got a -30 cold snap and it was later determined that the local fuel was only being treated to -10F. I was working in Denver, all our equipment gelled up. Not a bottle of 911 to be had by 8am, trucks scattered on the sides of the roads everywhere. I drove up into the mountains and bought a couple cases of 911 for the job. Probably could have made some bank driving around town selling it for $50 a bottle!
Other places to look out for are particularly low alt warm climates that are near mountains. IE you could buy fuel in Vegas and gel up in Utah because you could make it there in 1 tank of fuel. There's actually signs on I -15 going North out of Mesquite NV that they sell winter blend fuel. Last winter we were down in Vegas/Mesquite and then went up to Park City. 70 deg 1 day, -15 that night. I ran anti gel because I still had some desert fuel in the truck when I filled up on the way up to SLC.
