LiquiMoly Ceratec

I'm looking for feedback on Liqui Moly products — specifically Ceratec. I've seen reports suggesting that adding Ceratec (or similar additives) during oil changes may help reduce or prevent bore scoring. According to Liqui Moly, usage is one full 300 ml can should be used with 3–5 liters (3.2 to 5.3 U.S. quarts) of motor oil. For our cars, that would mean using two full cans per oil change. That adds significant cost and also seems like it could alter the oil's formulation. Does that seem reasonable? Are there better alternatives?
