one good thing about lubegard strategy is you can wait to dump it in, so in the future someone can gauge engine noise that way, see how oil is and then ad the biotech. I would say hemi tick is it's own thing and different the "engine noise". In the wife's SUV 5w20 redline was quieter then PUP 5w20, but went to 5w30 pup and it was quieter then redline 5w20. In fact I had to change it's name from the old rattle trap because the rattle was gone on 5w30 pup. However, the 5w20 redline erased my hemi tick. bottom line use whatever works, for sure the answer will not always be redline, there is no one product fits all here.
