Fuel Requirements
Aviation grade 100 LL (blue) or 100 (green) fuel is the minimum octane
approved for use in this airplane.
Use of lower grades can cause serious engine damage in a
short period. The engine warranty is invalidated by the use of
lower octane fuels.
Filling Fuel Tanks
Observe all safety precautions required when handling gasoline. Fuel
fillers are located on the forward slope of the wing. Each wing holds a
maximum of 40.5 U.S. gallons. When using less than the standard
81.0 U.S. gallon capacity, fuel should be distributed equally between
each side.
Have a fire extinguisher available.
Ground fuel nozzle and fuel truck to airplane exhaust pipe and
ground fuel truck or cart to suitable earth ground.
