    I know this seems to be the wrong time of year to be asking this but I was recently in PA when they had this late cold spell in the Northeast.

    I woke up and checked the outside temp display and it said 12 degrees and instantly realized I had forgotten to put anti-gel in the fuel tanks. I was afraid to start the engine because any gelled fuel would clog the fuel filter.

    I called the shop at the terminal and they said to put the anti-gel in the tanks. So, I added the anti-gel and everything was fine.

    It was my understanding that after the fuel has gelled it's too late to add anti-gel and that's when you use the 911, which can only be used by a road service tech or shop for some reason with my company. I don't know if the fuel was gelling, I just assumed that because the temperature was 12 degrees it might be a problem, but maybe that's not cold enough to cause serious issues.

    Diesel gel up around 10-15 degrees depending on the fuel, what treatment is put in and water in it.

    If it was just a overnight freeze, I wouldn't worry about. I was in PA/NY border last night and it fell below 30 and snowing but it warm up later.

    Your filter and fuel lines would likely gel first anyway. So not starting the truck would not really help you any.

    Fuel tends to take on a waxy/butter look when gelled. If you shine a light down in your tanks and it looks fluid still you're probably ok.

    Never thought of doing that. I guess like a bottle of olive oil if you put it in the fridge.

    If northern fuel "gelled" at 12 degrees F this nation would come to a standstill in the winters. With northern fuel I don't even begin to worry about issues until forecast lows drop below 5 F for more than about 5 hours of engine off time

    Sounds like some here are heavily invested in Power Service or other similar company.

    21 years out and have never had a gel issue. Never added any fuel treatments. I do idle if it gets below 0 to -5f.
