If Diesel fuel which contains moisture is used the injection system and the cylinder liners / pistons will be damaged. This can be prevented to same extent by filling the tank as soon as the engine is switched off while the fuel tank is still warm (formation of condensation is prevented). Drain moisture from storage tanks regularly. Installation of a water trap upstream of the fuel filter is also advisable. z Fuel oil selection chart #) Not specified In ASTM D 975 +) Differs from ASTM D 975 NOTE : The cloud point should be -12 ° C (10 ° F) below the lowest expected fuel temperature to prevent clogging of fuel fitters by crystals.
