I mean for a given displacement, the 8 cylinder is less efficient than the 4.
Yes if it can reduce engine friction by %50 (which is 10-20% of engine only losses) that would be a 5-10% increase in efficiency in itself.
less moving "parts" is good too.
Not sure about the change in piston motion, how that plays out.
