Does this Yamaha generator use mixed gasoline?
Pete 
from New York 
February 08, 2017
Answer
Yamaha recommends using 86 Octane fuel or higher. This unit does not require any mixing of gasoline or oil. Owner's Manual.

Can this be converted for propane use?
Peter G. 
from California 
December 15, 2016
Answer
Yamaha does not offer a fuel conversion for any of their generators and adding an aftermarket one will void the warranty.
