Low Temperature Operability or Cold Weather Operation

All Diesel fuel contains paraffin waxes which are crystalline in nature containing straight chain (normal alkanes) that will begin to solidify at low ambient temperatures forming a gel that collects on the fuel filter restricting fuel flow to the engine. Low temperature performance of diesel fuel can be characterized by its Cloud Point and Cold Filter Plugging Point (CFPP) and Pour Point
