I use it with great result. Look at my oil analysis with Ceratec and MoS2 here => https://www.zpost.com/forums/showthread.php?t=1461006&highlight=my+oil+analysis
MoS2 was tested at 49.4K miles and Ceratec was tested at 54.8K miles right before my rod bearing change. From the oil analysis summary table in that post above, MoS2 didn't appear to do much, but you could see how much Ceratec helped with reducing lead wear. Of course, this is only one sample point from my vehicle...so you mileage may varies as they say.
