Kind of an oil thread :(

Yeah, I know, who needs one? I pretty much pay no attention to the various oil claims and posts saying X oil is better than Y oil. But here's an interesting actual oil test someone did on a Norton Commando motorcycle website. It's worth a look. Whether it translates directly to the loads in an engine I can't say but it certainly shows some differences in the specific test. There are videos throughout the thread so look at all the videos.
