Truest statement !

There is very little difference in morn oils that met the latest API standard (SN). The biggest advantage of synthetic oil is easier starting in cold (below freezing) weather.

I was under the impression it with stood higher heats;; lasted longer and slightly better shear effect(better lubrication specs)

LOL at this reply must be all of 16$ to fill a gen with synthetic oil

That's what I've always used in our Onan, I certainly wouldn't be RVing if I couldn't afford a couple quarts of synthetic oil for our genny. Of course it's not required by Onan, as maintenance costs go their Onan oil is not all that much cheaper than synthetic oil off the Walmart shelf.

Yes. But not necessary.

I use the same oil that goes in the engine.
In my case that is Rotella T6 Synthetic.

By the way Sam, he is running an air cooled gas generator. I wouldn't run anything else but synthetic oil.

Once it's out of warranty and then only if you'll change it every 250 hours.

And for any air cooled engine running inside an enclosure like the OP's genny. On a 90+ degree day, the oil temp will be well over 250 degrees.

"In theory" the synthetics says you get longer oil change periods as the only real advantage.

Actually the major advantage is that true synthetic begins to break down at a much higher temperature. There fore it is superior in any application that has high temps. It is also claimed that it is superior in remaining on surfaces prior to startup. Most high performance engines with close tolerances require it for warranty and the Mercedes diesels even require their specs for warranty. It also is superior for lubrication when condensation may accumulate.

It is an excellent choice for any engine that may sit for periods of inactivity.

I just want to do what is best for it,I don't want any trouble !!!!

No trouble. I run it in all my engins. It is authorised by Onan/Cummins. I want the best protection I can get. Will one of those people who say you don't need the protection be around to help with any repairs?
