Choosing the right fuel
At operating temperatures below 0°C (32°F), use a blend of No. 1D and
No. 2D Diesel fuels, also known as winterized No. 2D.
Do not use diesel fuel blended with waste oil in engines equipped with a
catalytic converter-muffler. Blending waste oil in with the fuel will plug
the catalytic converter-muffler, resulting in a significant loss of engine
power. Your emissions warranty will be voided if blending waste oil with
diesel fuel is practiced.
Use low sulfur (less than 0.05% by weight) fuel as required by the EPA
for emission compliance.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.
Running out of fuel
Avoid running out of fuel as this will allow air to enter the fuel system,
which will make restarting the vehicle difficult.
If you have run out of fuel:
• If your vehicle is equipped with dual fuel tanks, add at least
15–19 liters (4–5 gallons) of fuel to each tank before attempting to
restart the engine.
• If your vehicle is equipped with the Caterpillar 3126 B engine,
the fuel system must be primed before attempting to restart the
engine. Refer to the engine operator's manual for instructions on
priming the engine.
• Use caution not to overheat and damage the starter by cranking
the engine for an excessive period of time. You may need to crank the
engine for a longer time than normal. If the engine fails to start in 30
seconds, turn the ignition to the OFF position and wait for two
minutes before cranking the engine again.
• Any remaining trapped air will self-purge from the fuel system once
the engine starts running.
• The engine may run rough and produce white smoke while air is in the
fuel system. This is normal and should stop after a short period of time.
