Biodiesel - Mack Granite GU Series Operator's Handbook Manual

MAINTENANCE AND LUBRICATION 279
CAUTION
Ultra Low Sulfur Diesel (ULSD) fuel with a maximum sulfur content of 15 ppm
must be used in order to meet Euro4 engine emission requirements.
Using otherwise approved diesel fuels with a maximum sulfur content greater than
500 ppm may shorten engine life and void the engine warranty.
Air is always present inside the fuel tanks, entering mainly through the tank
ventilation. With the air being heated and cooled, condensation is formed and
water is mixed in the fuel. To avoid condensation when the vehicle is parked
for longer periods, fill the tanks up to 95% of capacity. Do not fill more than
that, as the fuel needs to have room for expansion during the heat of the day.
