Now I don't know about the Yamaha, but I was warned by the honda techs that using synthetic in the EU series caused a problem with the low oil sensor. They were issued some tech alert from Honda == for some reason synthetic builds up in it or something causing them to fail a LOT sooner than normal.
So just make sure you use what they suggest in the manual. Nothing like a damn sensor failing that keeps you from being able to start your gen!!!
