Lucas 10866 Anti-Gel Diesel Fuel Additive 64 Fluid Ounces for All Diesel Engine Applications

I used this for my home To stop my heating oil from gelling. It worked well just add it to your oil tank before your fuel oil delivery.

i use this in my Kenworth with a C-15 Caterpillar engine. im not over the road for the most part any more. i do use it when the temp drops below 32° overnight because my truck is off most nights. i have two 150 gallon tanks. i keep above half full in the winter and treat with a half bottle per full tank if its going to get below 30° like tonight it will be 10° without the wind chill. and i have never had a problem with gelling. i do use a block heater also and when i treat my fuel i make sure its had enough time to run all the way through the fuel system lines and filters.
