If you sit in drive idling longer it'll drop down, when you initially get to idle it takes a couple minutes to drop.I watched my rpms and oil pressure today and idle with it in park it was 36 but even putting it in drive would bring it up to 50 to 52- so it looks like it does not take many rpms to get it to 50 psi or better
I moved to 5w-30 because I tow a lot and my oil temp is high. Redline is the best oil for these hemi from lots of folks recommendation here.Laramielambo - I've had the same experience. Bought a brand-new 2019 Classic with the Hemi after repeated issues with my 2015 EcoDiesel. (I know - another entirely different topic there for sure!) Anyway, when showing it to some work colleagues a different times the first week or two I had it, starting it up would reveal a horrendous 'tick.' It DID indeed sound like it had no oil. I performed the first oil-change after break-in and put the recommended 5w20 oil in it, but went to full synthetic Mobil 1. I can't recall having heard ticking since I did that. Just turned over 12,000 miles, so it's probably still breaking in.
So is there a benefit to moving to 5w30 on the next oil change, or a good additive at all? Thanks gang.
Thanks for the indepth review of the cam failure problems with this motor. I agree 100% with all your findings... I now see why Chrysler can't come up with a fix it would take a complete block redesign and Billions in warranty block replacements.. I will just make sure that I keep the idling to a BARE min and When I replace this truck if nothing is done on Chrysler 's part in redesigning the block I will not purchase another one.. I would hate that because I really love my Bighorn...
Thought this was worth sharing
This video pushed me over the edge. From no local parts stores carrying the approved oil, to the annoying MDS. I'm not sticking around to have this failure for the money I spent. Out she goes

Uncle Tony doesn't know what he's talking about though. There is an oil galley right where he says there isn't oil.
My Hemi has 224,000 miles on it.There are many owners of the Hemi's who have reached 200K - 300K miles on these engines. If this was a wide spread problem I don't think these engines could eve reach these milestones. It would be almost imposible for a Hemi engine to reach 100K miles. There is a company that makes lifters for the Hemi's that lubricate off the cam gallery sending oil up thru the pushrods to the rockers, this could be a fix. I run AMSOIL 5W30XL synthetic engine oil in my 07' Hemi, and it rarely ticks. I am not sure the tick on my engine is from the exhaust manifolds.
They also say the 3.6 lifters are failing. Yet the fleet we use has used 3.6 equipped vehicles for 10 years or so and haven't had any lifter failure that I am aware of. And believe me, they get a minimum of maintenance - but oil does get changed every 5000 miles.
If 4/5 of every mopar (3.6/5.7/6.4, etc) had lifter failure, you would hear about it.
I don't know of anyone personally that has had lifter failure.
There are definitely some years worse than others and 13 was one of the bad years - which points to a supplier issue more than a design issue.
The oil formulation changes in recent years has only made it worse.
Unless you run special oil or add additives to an older hydraulic tappet motor ( pre 1980), your chances of cam failure go way up vs. unheard of decades ago - well at least on the mopar line.
