I stick to what the previous owner used - namely Mobil 1 Synthetic oil. I think it is 0w40. I use Hengst oil filters ordered from Pelican Parts. I don't like making changes from OEM but I do my own oil changes and save big $$$. Yes if you don't have it would suggest you get Wayne's 101 Projects for the Boxster at Pelican Parts - $30.
Pays for itself in no time if you do just the basics like oil and filter changes...
Yes and welcome to the forum!
