As mentioned on many previous threads: upon starting the car, the 5W40 or 10W40 will "stick" to the cold engine parts better, whereas the 0W40 will tend to "run off" the engine parts more easily. If yolu live in cooler climates, the 0W40 is probably preferred, as too much viscosity upon starting the car is not desirable. If you live in warmer climates, the 5W40 or 10W40 may be preferable, as it won't be too thin when you start the car.

Most of us on here use straight olive oil. It’s pretty cheap at costco. Olive oil also has a very high smoke point. Lots of threads on rennlist about this idea. You just need to search about it. I have been leaning towards using the virgin branded options. I to am reluctant to follow the Porsche owners manual. I think they are in bed with big oil.

Oh the endless discussion about which oil is better... I'm going to miss it when we all start arguing about which charger is better for our 911 Carrera E.
"If you track, I recommend you the yellow charger. If you don't track then the black one is just fine"
