Whats the application? Intended use? You can defiantly tell a diff turning the same engine over by hand using low tension oil rings, then same engine with standard oil rings.
So theoretically there is some power to be gain by friction loss.
I run a vacuum pump with low tension oil rings to help control the ring seal.
If this is not a all out effort type engine deal forget the low tension oil rings.
