GasHole is on a distinguished road

Your choice on the brand of synthetic. I personally will use Mobil 1 as I have for years in all my vehicles. I'm sure Amsoil or the purple stuff, or whoever else's has some scientific mind-boggling molecular data that makes it better, but I can buy Mobil 1 right off the shelf at WalMart or Advance Auto Parts any day of the week....
and YES, you must use 5w20 as specified, due to the MDS function. I change mine at 5,000 using synthetic. I will change it out from the factory fill this weekend at 2500 miles. Just my way of doing things. I think the book says you can go like 7500 miles or something....screw that.
