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...

Newer Onans use splash lubrication, which is harder on oil than pressurized systems. I'd run dino oil for the first couple oil changes so the generator engine is broken in, then switch to synthetic.
