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.
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.
