I have always had a very noticeable hemi tick so figured it give it a try before i try a better oil to elimanate the tick. I have a 08 with 95,000 mi....Anyways .Added half bottle to my oil & half in my gastank. Started her up..and boom!..ticking no more! Completely gone! Added to my dirty oil too!!...wow!!! Cant believe it! Sounds like a whole new truck for only $6 .....Hahaha!!!! .Yep Your welcome!
