I have had a few 5.7s, older 05 gen Durango, sold it with 185,000 miles, a 13 Ram 5.7 traded it in with 125k, now my current 21 bighorn 5.7. Never had the Hemi tick in any, just manifold bolts broke and were replaced. I only use PUP and 8oz of lubeguard biotech moly enhancer, in bigger bottle they call it lubeguard heavy duty. Pup was just on sale for $20 a jug too, so bought 6, cant beat that deal. The lubeguard is only engine additive I will use. I do use fuel injector cleaner (has to have PEA) additive to gas regularly and feel improvement after a tank, I double dose the recommended amount once a year in tank. I change my oil at 8k miles, so for me is about once a year and always used Puraltor boss 20k oil filters. I have run the valvoline restore and protect in other vehicles and my riding 26hp lawnmower, if I ran it in my hemi, I would run it like 4k miles to clean up engine, then go back to the pup and lubeguard.
