It won't hurt a thing, but it will clean up an engine, better and cheaper than Marvel Mystery oil, or Rislone products. Never had any engine opened up for any reason yet. That's on many engines and cumulative mileage easily of over 1M miles. It won't hurt your engine to keep ATF in the oil year round.
That's a lot of ATF for our engines.
