The way I look at it is.... If the engine was designed for Synthetic then use Synthetic (never go to Dino oil). But if it says Dino oil or better .... then Synthetic is OK if thats what you want to do.
Keep in mind this tread is talking about an old school, air cooled, carbureted, single cylinder engine (Im assuming he has the Onan 4000 series) not a modern Car or truck engine that even seems to be talking about now.
Those two are miles apart..... as far as tech goes.
But I plan on changing to Synthetic oil on my Genny as well.... now that its broken in.
