I was actually going to try this oil in a race bike in the early 90's (factory RS600 long rod). Neo claimed a 20% or 20 degree (can't remember now) tempurature drop at the head with this oil in road race inline fours. The only reason I didn't try it was that I had a hairline crack in the camchain tunnel that seeped oil using 30wt and I was sure that this stuff would pour out the crack. After I rebuilt the engine with a new cylinder, I was going to try it after break in but quit racing and sold my stuff before I got around to it. I have the gallon that I bought then, around 1994, and would be willing to donate it to the cause if someone wants to run it.
FWIW, I ran alot of different NEO oil and always had good luck with it. They were always very forthcoming with me about their product, although I didn't ask the questions that I would ask now after hanging around here.
Cheers,
Dana
