My Prius and Fiat both came with synthetic oil. All Piaggio bikes like the Tuono, RSV, Vespa, and even a 50cc Sportcity scooter...they all come with full synthetic from the factory too. As far as the first oil change, that seems to be different. For the Prius it is 10,000 miles for the first oil change which is longer than usually recommended fro the first oil change. Fiat it's at 6 months, and the Piaggio bikes all call for the first oil and filter change at 600 miles, so apparently there is still break-in metal in the synthetic oil, just like with dino oil. Anecdotal cause when I do that first oil change, both the filter and oil always look brand new. Someone said if you look closely you can see shiny metal flakes in it, but I can't. ?? With my Triumph, they did start out with dino oil and went to synthetic at 500 miles. As you can see, the recommendations are all over the place. Some say use it from the beginning to never use it. I got my dino oil out at 45 miles and put in full synthetic for my Ninja 300. Seems like with time, more and more mechanics are recommending synthetic earlier and earlier though.
