I wouldn't call it a "close cousin". The two Ultra Euro grades are in fact very different, meant for different applications. The Euro 5w-30 is a low-SAPs oil designed specifically to meet various modern diesel specs and to protect those engines' intricate emissions equipment (DPF).
And the whole argument here was that due to sulfur levels in US gasoline, many German MFGs advise against the use of such low-SAPs oils in their gasoline engines here, presumably because the weak add pack may not be up to the task of making it through the entire extended OCI which is sometimes as high as 15K miles. Now, if you're not going to follow MFG OCI recommendations and just change it every 5K miles like dbrowne is doing, then there shouldn't be a problem. And the benefit of running a low-SAPs oil in a DI application is that it should result in fewer valve deposits, at least in theory. I don't think we have enough data yet to confirm nor deny this claim at this point.
On a side note, I find it a bit amusing that Pennzoil calls the Ultra Euro 5w-30 "a low volatility" oil despite its Noack being 11%, the same as for Ultra Euro 5w-40. At one point in time, I've questioned SOPUS on that figure, because in order to meet MB 229.5 spec, an oil needs to have Noack of no more than 10%. A SOPUS employee responded that the 11% figure in the spec sheet was wrong and that in fact PUE 5w-40 has Noack below 10%. They promised to update the spec sheet. They never did.
