Personally, I start adding it to every tank when the temps consistently get below 32F... but around 20 and below is when things can get bad. Along with the fuel gelling, there is also moisture concerns.... so more is better than less and earlier is better than later.
Use Standyne, Powerservice or Howes for consistent performance and lubrication benefits of the fuel pump and injectors.

It's been -25 degres F here in MN and I'm having some gelling issues. Use power service (white bottle) double strength in every tank. I had to put in a bottle of power service 911. Hope it will clear it up. The fuel I put in is rated to -30. This is the second time this winter this has happeded.

There have been several threads on FTE this year about gelling fuel, I am seeing ULSD gelling even treated at temps that it shouldn't. We run winter blend fuel here in Iowa treated the fuel in the semi friday with enough to treat 250 gallons in each 150 gallon tank, and today it was 5 above, and got down to -3 last night, and it was starting to gel. Now winter blend fuel without the treatment should not have gelled at those temps, plus some old LSD fuel I have in the garage that was treated with Howes last spring (straight #2 not even winter blend) was less cloudy than the stuff I pulled out fo the semi today. I am thinking that ULSD has changed all the rules on when fuel is gonna gel.

It's been near zero here in Michigan and I have yet to experience fuel gelling. Never happened on my 3 7.3's or any of my medium duty trucks. Michigan winter blend fuels must be better than some ot the others.

All depends on where you live and the temperature. Most Winter blended fuel does alright right out of the pump so long as you stay in that same geographical area. We sell a whole lot of the Stanadyne Winter 1000 and E-Zoil D-Gel additive to big rig owners because they may fill up here in New England and then drive north to Canada where it's colder and they can have problems. To answer your question more directly, I'd say 10F or lower is where you should be concerned. That's just my opinion and other factors need to be considered, but just a rule of thumb. I run the Stanadyne Performance formula year round and have never had a gelling problem. If I were to go further North I'd add a little Winter formula.
