Read up on oil from BR's link from page 1.
Then BLS also made a post on page 1 regarding issues with the wet clutch. All your questions are answered in this very thread.
I have read all the threads above and on to the links as well. I kind of glaze over after a few pages. I just picked up some 7317 filters at Wally-World, and I know BR switched back to M-1. I picked up some non Delvac M-1(probably my mistake) (assuming its automotive) and wanted to verify before poring this into the VFR. Maybe I will just go back and pick up the Rotella. Opinions on Oil are like.........belly buttons, and everyone has one. I just try to see what the majority of folks use, then filter that with the the opinions of the people that I think that they know what their talking about and pick from there.
Edit:
I knew I read it somewhere...
I think I may have answered my own question.
Quote from "All about Oil" by Mark Lawrence
"Mobil-1 automotive oils all contain small amounts of moly - about 100 to 200 ppm. This can cause clutch slippage in some motorcycles. I've only heard of this being a problem in Honda Shadows. "
I don't ride a Shadow, and don't think I ever have. I did ride a Saber once, and that was close enough for me to know it's not my preferred riding style.
