a great product

  • By JimH in CA from Smartsville CA USA on Monday, June 30, 2025
  • Pros: no corrosion/rust , little wear.
  • Cons: a bit costly, but overhauls are much more costly.!
  • Review: I've used this with 20w-50 oil and my engine is running very well; no material in the oil filter, good compressions and 12 hrs per qt of oil use. Borescope shows ok valves.
    This engine is now 1,200 hrs past tbo, and still makes redline power on takeoff.!!

  • Review: I was told that it is a must for Lycoming engines to protect the cam from rusting. The future will tell
