I don't think thats true at all. there are a lot of arguments one could come up with against that notion, but one is MPG. Member andrew65 was getting 38mpg and after pouring some of the lucas stuff in got 42.85mpg. Thats a huge difference that I never see on mine except when i compare flogging the bike and riding like grandma. So unless he tested it while riding very differently than he does, there would be no way to explain a 5 MPG improvement. But more importantly there are a lot of people who report great improvements in MPG. We shall see. I know my bike's mileage like the back of my hand, so I will know if this works in that regard. And if it does then the only reason that could be happening is improved lubrication of the upper cylinders which any way you look at can only be good. On the other hand if you are right i'm out 4 bucks....i think i can still eat tomorrow.
