It is true that adding gasoline to diesel lowers its CFPP, but it will also lower the ignition point, which can cause damage and even fire in the engine, so this is by no means recommended. Jugopetrol’s high-quality diesel fuel can be used at temperatures which are lower that those prescribed by the standard, but if you believe that even that will not be sufficient for the location where you are traveling, you can try the anti-freeze additives available at our petrol stations. These additives react with paraffin crystals, affecting their shape and size, making it possible for fuel to flow at lower temperatures. For an efficient performance, additives must be added to the fuel prior to paraffin formation.
