Thanks Ernest, the chart is very helpful! The SG does seem to have the numbers in all the right places. A couple of people have also mentioned oil from the Harley dealer is good, but I haven't seen any of their numbers. I can put a bit of extra faith in what they're doing for BMW oil though, knowing the rings are laying flat in the bikes, as they are in my car. I would imagine this is something that has been taken into consideration when looking at ring wear in both engines.
