Engine Oil - Yamaha VIKING VI 2021 Owner's Manual

Unleaded fuel will give you longer spark plug
life and reduced maintenance cost. Gasoline
containing ethanol can be used if the ethanol
content does not exceed 10% (E10). Gasoline
containing methanol is not recommended be-
cause it can cause damage to the fuel system
or vehicle performance problems.
Portable fuel containers
If you carry a portable fuel container in the
bed of your Yamaha Viking VI, be sure to se-
cure it with the cap tightened before driving
the vehicle.
Always place a portable fuel container on the
ground before filling it. Before removing the
container cap, touch the container with the
fuel dispenser nozzle. Keep fuel dispenser
nozzle in contact with container inlet when fill-
ing. WARNING! Never refill a fuel container
in the bed of any vehicle. Fire may result
from a build-up of static electricity. The
discharge of this build-up while refueling
can cause a spark and ignite the gasoline.
