It may live up to it's claims, but I'm a sceptic. At 68 years, I've seen lot's of gimics, gizmos, and gunk who's real claim to fame was to make somebody money.
Opti-2 is a mineral oil, witha specific additive package. We've had automotive oil with all sorts of additives, including teflon, boron, graphite, moly, chlorine compounds, zinc, phosphers, and others. Some work good, some not so. Opti-2 relies on the antiwear compound "sacrificing" itself, instead of the metal, and producung a very high heat at the bearing that will allow for the metal to "move" and thus fill in the machine marks and imperfections from manufacturing. Are you really comfortable heating up the bearing surface to a degree that the metal "moves"? Is there perhaps a heat treatment in the pieces of a roller bearing? If you are heating the bearing to a point that metal is moved, will it not muck up the heat treatment.
As I said, I'm a sceptic. Other oils have additive packages as well. The base stock of Opti-2 is mineral oil. So why so expensive? A little Zinc, Boron, or Clorine compound shouldn't raise the price to a buck + per ounce. The whole thing reminds me of the late night infomercials where they take two engines, pour the secret compound in one and let it run for a while, and then drain the oil until one quits, and of course the one with the secret compound is running good. sure
