I've noticed that the little gear assembly isn't at all like the inside of most engines, and that making the oil stringy like that offers the opportunity to whip a lot of air into the oil. Air is a terrible lubricant.
I generally stay away from any product built and sold on marketing alone, like Lucas or Scamsoil.
We ran tests on our drag bike, And Royal Purple was by far the best, Scamsoil the worst, but Scamsoil paid so that's the sticker that went on the bike, even though RP was in the case.
Personally, I just use Mobil1. Good enough for OE, good enough for me!
