Internals of an oil pump are like wagon wheels. it takes a little oil in the wheel and spits it out, so it's a fact at most the psi difference between 5w20 and 5w30 is 2, as in an engine that is running at 55 psi common for the hemi, might see a psi as high as 57 with the switch to 5w30, in other words, the gain to lubrication is slight because the oil pump is an equalizer and there is not much viscosity difference between the two oil weights. So don't go dumping that oil. In general yes I use 5w30 because I will take whatever gains I can, but 5w20 killed my tick the same, but it took 500 miles to do so. Noted, some guys 5w20 redline doesn't work as good, and 5w30 does, so just going off that no reason why not run 5w30 next time.
The science of moly, it has to survive the heat and it takes time and pressure to "plate". Moly is what they use to combat dry starts. Now, some people believe that the poe and possible pao base oils also contribute to the silencing of hemi's, but there is no real data. Bottom line maybe as many as half of the hemi's on redline take at least 500 miles to go quiet, all the way up to 1700 miles and even 2300 miles. After 2300 miles I would call it as it lays, but unless you a it have 1500 miles on the current change, don't do anything, as in nada. I would however run the rpm's to 2500 and leaving it at that for a minute prior to shut down.
I like RP filters, my truck ticks on some filters but not these.
oddly my truck had a slight tick on my entire 10w30 redline run, but never in 10 years on 5w30 except that first 500 miles. occasionally if the truck sits or after a change it ticks for a second, but in general pick up use 10 years my hemi is silent.
