Peter, you can kind of disregard what I said with that quote. Since you scanned in what your owners manual said (I don't have mine over here in Afghanistan nor do I have any SB's here either), and it appears that it does give three different choices I may have been a little premature. I was under the impression that the Mobil 4T full synthetic was all that was used after the "break in" oil was drained out on the first service. As others have said if you go anywhere near the 10,000 mile service interval on the Rocket I wouldn't use anything but the full synthetic (while I was in the US in July I went ahead and had the oil changed out at 8,000 miles).
