I always carry anti-gel fuel additive with me in an MSR brand camping fuel bottle (prevents leaks and spills... in the 33oz size)... I carry 2 of them at all times for road trips.

I have a 44 gallon tank and only need 16oz per fill up, but will use all 32oz if real cold and extra piece of mind.

No matter what... even of the station states that their fuel is "winterized"... I always treat my own fuel... why take chances and I want to do know that it is/was done right and that I have the extra protection of cetane boost and injector cleaners.

Winterized could mean a blend of #1D and #2D... which has very little lubricity... or it could mean they dumped in bulk Powerservice into their underground tank when the tanker truck filled up the station... who knows... and if it it was done correctly???

I carry 2 MSR camping fuel bottles at all times (refilled from the large large 96oz jugs) and maybe keep a spare emergency small bottle unopened as a backup if on a large road trip.

I use Powerservice year round (white bottle/anti-gel in winter from November to March) and grey bottle the rest of the year).

Good luck... but the key is also to use OEM/Racor made fuel filters and to change them every 15,000 miles as well. Dirty fuel filters will clog quicker and not flow as well... and will allow gelling to stick to the sediment more easily.

Trust no one... change your filters on time with OEM filters and use Powerservice in the white bottle at every fill-up no matter what the stattion claims. The problems happen when you fill up at stattion that is in a warm area and you drive to a cold area or the mountains.. or s station that has not yet received their new supply of "winterized diesel" for that week or month.. so why risk it... do not trust anyone but yourself to do it right (or me.... you can trust me)!!!!!
