It is the general consensus among most German brands operating in North America that pretty much any gasoline engine should use the full-SAPS spec'd oil (i.e. MB 229.5, BMW LL-01, Porsche A40, VW 502/505), whereas diesel engines should use a low-SAPS oil (MB 229.51/229.52, BMW LL-04, Porsche C30, VW 504/507, etc).
However, when the gasoline engines in question feature direct injection, the jury is still out on that one
Really? VW 505 is a diesel spec, thus conflicts with your generalization of german diesels must use Low-SAPS.
Low-SAPS is a must for diesels that uses DPF and Urea Injection.
Yes, you're right, although the the point of my post above was not to discuss which oils are applicable for German diesels, but rather provide relevant information to the OP.
As per the OP's question, it was more to illustrate that his GASOLINE engined Porsche operating in North America should be using a full-SAPS oil (A40) rather than a low-SAPS oil (C30), more COMMONLY reserved for MODERN diesels WITH a DPF. Obviously, pre-DPF diesels can operate on oils with any level of SAPS, just as gasoline engines always have.
Also, to add to the above, I wanted to make the point that in North America, most Euro gasoline vehicles are spec'd for full-SAPS oil, whereas in Europe (where ultra low sulphur gasoline is available), the lower SAPS oils are often considered interchangeable with full-SAPS oils in gasoline engines, contrary to common practise here in NA.
MB is one notable exception as they are fairly clear on only using 229.5 in gas engines throughout the world.
