Been running the last 6k miles with Mobile1 0w-20 as well and have had no problems at all. It's very good oil for street driving. I do plan on going back to Motul back in for my next oil change next month.
FYI, if anyone here in The States is doing their own changes and didn't already know (or didn't read the thread posted above) Wal-Mart sells 5qt. containers of our oil for about $25. (
