Cold weather running conditions are not just a problem for starting diesel engines. Cold weather can rob a diesel engine of its efficiency and power by clogging the fuel filter with solidified wax particles. Although diesel fuels are usually formulated for the local climate, there is no guarantee that the weather will cooperate. Depending on the fuel, temperatures as high as 40°F may cause the paraffin waxes in diesel fuel to begin to solidify. This problem worsens as temperatures drop. Eventually diesel fuel reaches a “pour point”, where the solidified wax is so concentrated that fuel stops flowing and becomes unusable.
