Oil could make a difference but i am very surprised it's that much.

what weight oil and is it any kind of special royal purple oil? I'm not familiar with them.

I'm somewhat sceptical about this. I can see how there might be a difference, if the new oil generates less friction, thus allowing parts to move a little more freely, but, well, not convinced. If it really was that big of a change then we'd see everyone doing it. Having said that, if it's back to back runs on the dyno on the same day, and short time period and same conditions (time of day, temp, stuff like that) then it's very interesting.

I am skeptical as well. I try to look at it from a logical point of view of the system and I don't see how it could make a measurable difference.

Horsepower (HP) is a derivative of Torque (TQ) and engine RPM. The engine makes torque from the combustion process inside the cylinder applying rotational forces to the crankshaft.
Friction plays a role in that process, but can the viscosity of the oils be that much different to allow the piston rings to scale the cylinder walls that much more efficiently? and at a measurable level?

The coefficient of friction between the piston ring material and the cylinder wall material is already low due to the lubrication, but can there be that big a difference in the lubricating characteristics of the new oil to make a measurable difference in torque output?

I've never experimented, and I would love to have my skepticism corrected. Then comes price, how much is anyone willing to pay for that, and pay for that repeatedly since oil is a wear item?

I hope it works cuz I'd be that guy too :)
