I like Castrol for smoother, quieter than Mobil or Fuchs in my Benz. Blazer doesn't care what's in it. No brand loyalty, doesn't care what flavor either!
My motor-cicles are happiest on Silkolene. Neither likes Castrol. Yamalube is pretty smooth too. Not going to get in a "you can't feel the difference in your motorcycle shifts" or "it can't be quieter" bologna because, yes I can and yes some oils are. Different oils make a big difference, and if you can't feel and hear it, well, this is BITOG - follow the sheeple.
I have already got those two trolls on ignore. Not that I'm giving advice.
