Engine output actually may not be affected by poor ring sealing which is causing oil consumption. Depends which rings are at fault. Failure or poor sealing of the oil control ring and/or the 2nd compression ring can cause oil consumption, but not necessarily a large loss of power since most of the cylinder sealing is accomplished by the top/1st compression ring. Power WILL be lost by inadequate oiling of the wrist pin, piston skirt, etc. in those cases, however. But that power loss would be negligible until you had a wrist pin seize on you.
