Oil pressure on 6.4, what is yours, how many miles

30956 9
I just bought my 2015 SRT 392 few days ago, looking at the oil pressure gauge, fully warmed up at idle I have 31 psi, down the road doing 75 mph I have 55 psi. Fresh oil change by previous owner.

My car has 50k miles

Like to compare to what others have in their 6.4 hemi.

Those pressures the OP posted is right where the 392 engine runs at.

If the oil is colder (or ambient temps are cold - winter) it will go up a couple of points

The highest oil PSI at startup I've seen is ~ 75 PSI on both my 5.7 I used to own and the 392.

My GM cars that had oil pressure gauges would often indicate 80 at cold startup (5W -30 with those).

I take it easy on cold drive off to allow the oil to circulate, especially the valve train. That higher cold viscosity will take a bit more time to get to those tight clearances, plus the parts contract / expand with temperature as well.

During the warmup (oil temp < 100*) I'll see idle PSI 55 - 60 as its warming up. Typical operating temp will vary from 194 - 215* with temperatures from 25* - 55*F ambient.

The conditions in which you're driving stop/go, highway, grades/hills, extended idling will have an effect on oil temps.

At times I've seen idle psi drop to 29 sitting on a hot day and oil temp is 220*+. When you're rolling and air is flowing through radiator and getting coolant back to the 203*F point, oil temps settle back to 215-217*F

I run the virtual gauges on Perf. Pages so that info is present when I'm driving. If using Nav, I'll have the PP running in the background and can switch back / forth.

There's times when it would be nice to have the virtual gauges in the center and have horizontal bar graphic for multiple items (user selected) to monitor things. The center cluster only shows one item as a virtual gauge at a time...
