    Its' going to be cold and I don't have a lot of PS Antigel left but I have a lot of 911 left.

    Can I add the 911 to the tanks instead? The web site says "Diesel 911 does not prevent fuel gelling".... so I know their answer but does anyone know why it won't prevent gelling yet you can add it to re-liquefy and de-ice?

    Thanks.

    It's going to be cold means a lot. Give a temperature otherwise no one will know. Depending on where you fueled you may not need anything

    Ask the truckstop clerk if the fuel is blended and to what temperature.
    0 degrees isn't so bad.

    I would say that the supplier does not want people using 911 as preventative on a regular basis. If it's all you have on you, I say throw it in.

    To add......I would never trust any fueling station that says their fuel is treated to a certain temp. Better to add your own and know for sure. Just not worth being stranded and froze up.

    Every time a truck gets towed in and gelled up I hear "but the pump said it was pre-treated" or "we only buy treated fuel". Yup.......sure it is. Tell that to the ice growing on your fuel filters.

    Today I was going to through in a spare bottle of Forte I have, until I read the label and it said anti-gel good to -05C.
    It was -33C this morning.

    DO NOT add 911 instead. It liquifies gelled fuel and the manufactuter specially states it is not an antigel.

    Most truck stop fuel is blended for 17 degrees this time of year. You’ll be fine to get to the next stop to get some diesel treat. I always use Power Service. One Botlle for above zero, 2 bottles below zero ambient, 1 bottle = 250 gallons. I only have 200g capacity, increase as necessary.

    911 is mostly methyl hydrate or something similar by the smell .. it works at de icing but isn’t friendly to seals and valves .. as stated above get some #1 diesel and not worry about freezing
