RP 20-500 Higher idle oil pressure?!?!

[NETim]

I changed the oil on my '14 today. Just a tad over 4K on the oil. 97K on the truck now. I used an RP 20-500 for the first time. Previous filter was an RP 20-820. It appears I have gained approx 3 psi at idle, from 33 to 36 PSI. I see no difference at higher RPM's.

The only other change was I went from Shell Gas Truck 5W-30 to PUP 5W-30. And as usual, 15 ounces of Lubegard.

It idles so quiet.

I'm going to keep an eye on the idle oil pressure and see if it goes back to 33 like it has been since I bought the truck.

Is that good or bad, lol? Really interesting and I don't know the answer, I can say not all psi is good, case and point the 10-48rp cousin filter which is related to the 20-500. Some psi is restriction of flow and some psi is actual flow within oil lines - as the main cause. Which also means not all psi increase is bad, lol. I'm not tossing my hat into this one, just stating my opinion, fact is 20-820 is so hard to find it is nice to have an option.

You raised psi but you didn't get the bump from the oil pump.

I dunno what to make of it. Truck runs very quiet. PUP 5W-30 slightly thicker than Shell Gas Truck 5W-30? I dunno.

Nothing to worry about for sure, didn't mean to imply that. One thing for sure, hemi's tell you when something is wrong.
