MAINTENANCE AND LUBRICATION
437
Diesel-powered engines for heavy-duty trucks built on
or after January 1, 2007 are designed to operate only
with Ultra Low Sulfur Diesel (ULSD) fuel. Improper fuel
use will reduce the efficiency and durability of engines,
permanently damage advanced emissions control
systems, reduce fuel economy and possibly prevent
the vehicles from running at all. Manufacturer
warranties will be voided by improper fuel use.
Additionally, burning Low Sulfur Diesel fuel (instead of
ULSD fuel) in 2007 and later model year
diesel-powered cars, trucks and buses is illegal and
punishable with civil penalties.
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.
For additional information about fuel, refer to the Operator's Manual
Vehicle Maintenance.
