Unleaded gasoline 87 Octane or higher
We DO NOT recommend the use of ALCOHOL
bearing fuels in any of our products. The use of
these fuels may create a potential safety hazard.
NOTE: The use of alcohol bearing fuels can
cause engine malfunction, particularly "vapour lock"
at temperatures above 50° F (10°c C).
NOTE
• NEVER use No. 2D at temperatures below
20°F (-7°C) unless you are sure it has been
“winterized”. Cold temperatures will cause
fuel to thicken which may keep your engine
from running.
• If No. 1D is not available, a “winterized” blend
of No. 1D and No. 2D may be available. This
blended fuel is usually called No. 2D also and
may be used in colder temperatures.
• If the vehicle fuel tank is being filled for the
first time or if the vehicle was allowed to run
out of fuel, it will be necessary to bleed the
air from the fuel system (refer to “Bleeding
The Fuel System" in the Maintenance manual
).
4.8 FUEL RECOMMENDATIONS - DIESEL
Fuel tank should be filled to within 1/2", (13mm)
below the bottom of the filler neck. DO NOT overfill
the tank.
Use #2 diesel fuel (ASTM No. 2D) when
temperature is above 20°F (-7°C).
Use #1 diesel fuel (ASTM No. 1D) when
temperature is 20°F (-7°C) or below.
4 SPECIFICATIONS
Gasoline containing ALCOHOL can cause
deterioration of some non-metallic
materials in the fuel system.
Fuel hoses must be inspected frequently
and replaced if excessive stiffness,
deterioration or fuel leakage is found.
Gasoline Containing ALCOHOL will
attract and hold moisture inside fuel
tanks. Moisture may cause corrosion of
metallic parts within the fuel system.
Fuel leakage from a fuel system can
occur while the system is in use, in
transit, or in storage. Such leakage can
contribute to an explosion or fire, causing
serious bodily injury or death.
