Air cooled engines run hotter than water cooled engines. Thus the manufacture does not recommend multi viscosity oils. BUT! that ruling was for non-synthetic oil. Standard oils loose their multi viscosity capacity when run to hot and thin out. So when running multi viscosity oils in air cooled engines, always use synthetic oil. I have the same generator as you and have used 10W-30 synthetic for 22 years with no problems.

Regular multi viscosity oil is fine in an air cooled motor, air cooled motors do not have a thermostat to make them run as hot as water cooled motors. There are no air cooled car or motorcycle engines anymore because they cannot get them to run hot enough for modern fuel injection pollution control systems.
