The oil pressure sensor was an oem mopar unit. I’ve used a mopar filter a couple of times and nothing changes. The truck has had the same readings for almost 20,000 miles with 4-5 oil and filter changes. I’ve used PUP, royal purple and mobil1

Nope you got that wrong,it's for 14 and newer,up till i think 2017 they had that note in the big manual and the online pdf file. Little tidbit for you the 5.7 was originally spec'd with 5W-30,only after they started going after milege numbers and fighting with the government nannies did they re-spec it with 5W-20.They removed the 5W-30 because of the government nannies,as the trucks supposedly wouldn't meet FCA's milege claims with 5W-30. The new trucks i think are spec'd with 0W-20 which is nothing more then warmed up ppiss
^Agree, I have a 2014 and it notes 5W30.

Oil pressure wise I run PUP 5W-30 with royal purple filter, warm idle is around 45/46psi and with the cruise set at 75/80 this see 60/61 psi. It’s smooth and quiet. I do need to pull the passenger side manifold though to machine flat and replace bolts, luckily the head snapped off and there’s enough stud to get a hold of.

How many miles when the head snapped Zeak?

I’ve got 70k now, it’s had the start up tick for a while but started getting loud and more prolonged maybe 3-4k ago. It’s quiet within 20 seconds after start up though. In the beginning, maybe around 30k, it would tick only if it had set for a week or more, now it’s pretty much any time it’s set for an hour or more.

I’ll take care of it this fall.

2021 15,000 eTorque Longhorne: for the most part 49-50 all the time, hot/cold idle, running on the open road, barely changes. Don't know what dealer used but I DO know I'm not returning @$140.00 per oil change.
