FUEL SELECTION – DIESEL
ENGINE
Refer to your chassis manual for the
manufacturer's recommendations on proper fuel
selection (ULSD fuel only).
Winter Fuel Waxing and Anti-Gel
Additives
In sub-freezing temperatures, #2 diesel fuel
can form small wax crystals that become trapped
in the fuel filter and block the fuel flow to the
engine, causing it to stall out. At sub-zero
temperatures, the fuel can congeal and turn
"slushy." If this happens, the only remedy is to
have the vehicle towed into a heated facility to
allow the fuel to warm up and become fully
liquid again.
During winter time, most truck stops and
reputable filling stations have winter blend diesel
fuels available that are less susceptible to waxing.
3-18
There are also commercially available
products (typically called anti-gel additives) to
add to diesel fuel while filling the tank to inhibit
wax formation in freezing temperatures.
Further Information
Consult your chassis manual or diesel engine
guide in your InfoCase for more information on
fuel requirements and additives.
FILLING THE FUEL TANK –
DIESEL ENGINE
Diesel fuel can foam up while being pumped
into the tank. Sometimes this foam can cause the
pump nozzle to shut off before the tank is
actually full. Allow the foam to settle, then
resume filling at a slower flow rate until the tank
is full.
STARTING AND STOPPING
DIESEL ENGINE
Refer to the chassis manual in your InfoCase
for the manufacturer's recommendations on
starting and stopping the engine.
See also "Engine Block Heater" in this
section.
Do not attempt to start the vehicle by hot-
wiring.
Idling Diesel Engine
NOTICE
Do not operate engine at low idle for long
periods with engine coolant temperature
below the minimum specification in your
diesel engine manual. This can result in
the following:
• Fuel dilution of the lubricating oil
• Carbon build up in the cylinder
• Cylinder head valve sticking
Reduced performance
