No disrespect, but of all the opinions listed, this is absolutely the worst recommendation I've seen. I would never run oil that heavy unless I was running a car with 250,000 hard miles in Dubai...in the summer.
What is your reasoning for running oil so for outside the parameters of what Porsche recommends and moreover with a viscosity far beyond what your modern engine was designed for?
