    Has anyone ever heard of fuel gelling due to a chemical reaction with an additive?

    I have not, But that does not mean its not possible.. I know some "additives" can bring the gelling point down, So instead of being safe up to neg 20 depending it can make it as much as Positive 20. With as much bio fuel as is in Diesel now adays anything is possible.

    I used Lucus. But about 2 tanks ago. When we stopped to put it in the shop on Saturday the fuel wasn't gelled. Its been sitting at the shop until today when they took it in the bay to look at it and now they are saying the only problem we were having is the fuel gelling. They say it's not weather related but that it must have been a chemical reaction even though its been 2 tanks ago that I added anything. I'm thinking an injector is going bad, but its not throwing any codes

    don't know about lucas, most people use that other stuff. can't think of the name right now.

    depending on where your at. if your up north. your going to be having problems. seems that some truckstops are still selling bio. which gells at 45 degrees. therefore, isn't used in the winter. yes, i used to haul the stuff.

    if you fuel up in texas where it's warm, and you head to the north. i gelled up in casper wy. last year.

    my last tank i filled up. northern utah. was pretty obvious it was bio. crap looked like pancake syrup. and the temps were 40 degrees. got to barstow cali. and had to change fuel filters.

    where at, is your truck at the shop at? if it sat outside for a couple of days and your in the north. and you filled up from southern temps. i cn see it gelling from sitting around.

    fuel can gell if you shut the truck down for 10 hours and use your webasto heater.

    We are in Amarillo. This is the furthest up north we have ran so far. When we took it to the shop it wasn't gelled, but Wednesday it was. They are saying it is not weather related gelling but a chemical reaction

    As cold as it has been in Amarillo my guess would be it gelled because of low temps.

    The mechanic at the Cummins is saying it gelled because of a chemical reaction not because of weather
