I am now at 115 hours on a new Superior IO-360 with the roller cam. I had a lifter issue during the first flight last fall. I only got 45 minutes of break in time before the issue and had to land. Superior totally disassembled the engine as the roller lifters can only be removed by splitting the case, changed the lifter, and ran the engine on their test stand at their facility (lucky I just live down the road). I asked about the cylinders since it took a few hours of run time to diagnose the lifter and the engine was not yet broken in during this run time but Superior thought it would be fine.
Over the last 35 hours I have used a quart of oil every 7.2 hours which seems high to me for a new engine. I am running between 5 and 6 quarts in the engine.
Any thoughts? What kind of oil usage are others finding on the Superior engines?
Thanks,
