    I have plenty….gel right up driving down the road.


    Must be Michigan just has crap fuel.

    -10f for more than 1 day and all hell breaks loose. Filters like ice cubes and can’t even see the bottom of most fuel tanks. Some have to come inside to get them thawed. Once you add some good juice they are fine.

    Untreated, no way.

    My expereince in the extreme cold has only been in my two trucks. No anti gel, 40 below and tanks are warm to the touch. No way it could gel.

    Last year I idled at 800rpm for two and a half days with the highest temp at -14, and my tanks stayed warm just idling.

    Yeah, I haven't seen tons of these situations, but the last 6-7 years we've had several times at home with multiple days below zero for highs.

    Lots of truck I had to work with gelled, but none that were running.

    I'm not sure the difference. The trucks that I've warmed up the left side of the engine to get thawed out, they ran rough for a few minutes after starting, but the hot return fuel took care of the gel in the tanks usually in less than 10 minutes.

    You could see the fuel in the tanks change from opaque to clear pretty quick with no external heat. That's at temps usually in the 0 to -10 range.

    Maybe some engines, IDK, don't move enough fuel. I've run a bunch though out of 5 gal buckets, and that fuel goes quick.

    Always treat your fuel if you fuel below i70/i80.

    Especially if moving south to North.

    The southern states are light on their "fuel treatment" if they even actually treat at all.

    The northern states have started to become lazy with their fuel treating as well.

    Im normally above i80 nowadays, I still treat my fuel.

    The company knows, $60-80 in idle diesel for the night is better than a couple thousand to get towed and pumped.

    Manufacturers also have a recommended temp for cold weather, and tell you to idle higher to maintain recommended temp. Failing to do so may result in gelled fuel.

    Ive read on here before several times at every winter about this gelling thing in the winter. No one has mentioned yet anything about KEROSENE(I wouldn’t know the mixed with regular fuel). Read that they use this liquid for you individuals that love to play in the wonder winter land. And @D.Tibbitt , I’m enjoying the 80* weather in SoCal part of Commiefornia, as well.:biggrin_2559:

    I suspect water or contaminated fuel from wherever you purchased it, or the place wasn’t selling straight #1 like they said.

    Either way it proves my point. If the lable says #1 but its not or something is wrong with it. Additive is cheap insurance.
     
    Feedman, Speedy356 and Long FLD Thank this.

    Kerosene is almost identical to #1; less additives and more refined to smoke less in lamps, but otherwise about the same.
     
    Opendeckin, Diesel Dave and ducnut Thank this.

    Everyone needs to heed this post here. Of i can help it, i will try to get fuel in cold weather states. Its definitely treated differently. You don't even have to add additive if you get fuel in a cold weather state. It can go into the negatives without anti gel. I also can attest to that statement of using too much additive. That happened to me, and I ahd to get out and change the filter in about 10 below temps. ½ bottle in each tank will do just fine, even in extreme cold temps. A whole bottle in each tank is wayyyyyy too much.
     
    hope not dumb twucker Thanks this.
