The 0/40 will work great and provide slightly better mileage, more power and cooler temps than a thicker oil. Porsche recommends it, and you want the thinnest oil possible. That is what I used in my Boxster, and use in my street 996 in our very moderate SoCal climate. For racing my turbo in the desert, I do use a 10/50, but I think that is a bit extreme for your usage.
