Generator oil change/sythentic ?
Hello: I have an Onan QG4000 generator that is due for its first oil change (20 hours). I have the owner's manual, and while it lists the correct oil based choices on temperature, it has no discuss...

I'm sure it would not hurt anything to use synthetic but I don't see any great benefit either, unless you use the generator a lot more than most people. I would go by the manufacturer's recommendation on this one.
