93k on the motor. the car doesn't see much every day normal driving. its a track car so its life is pretty much sit in the garage for a week or to. then get trailered to the track. beat on all weekend. then mid week i'll drive it to my friends shop a mile down the road for maintenance. so i'm not to sure about oil consumption rates. i'll keep an eye on it. i usually check the oil and fill as required during lunch time at the track. i haven't seen any knock except for a random one whille on the highway.
