2005 Jeep GC, Hemi, OCI?

No brainer. 5000 mile changes got it this far. Just continue.
5.7 ltr is the hemi. 50/50 city/hwy. Pennzoil, QS, or Castrol is what I usually use.
If thats daily than how many miles ? You may have to look at the UOA 's for that engine and a Syn user to get an idea or wait for someone to chime in.
I have been doing mine every 3K with 5W-20 synthetic. Mine is a 5.7L with eTorque.

We change ours by the OLM, has seen M1 EP 0w-20 since the first oil change at 1,150km to flush out the break-in material. OCI by the OLM varies between 10-15,000km (6,200 to 9,300 miles).
Blackstone suggested going 8-9K on Shaeffers 9000 on this UOA
5.7 L Hemi (79K) Shaeffers 9000 6000 miles
Lot of high RPMs too in this run. Didn't seem to mind it at all. Side note, that add pack in the shaeffers looks great. 320 ppm of moly + boron and titanium.

I have the 5.7 hemi in my Durango. Switching over to Mobil 1 EP 0w20. 70% PAO, one of the better quality 20wt synthetics out there. Currently running Mobil 1 truck and suv 5w20
I change my 2011 every 6 months with PP and a Fram TG2. I might put 3-4,000 miles on in that time. My driving habits are the reason I change it out every 6 months, even taking it on a 40-50 mile run 3-4 times a month, I still do a lot of short tripping. Cheap insurance for me.
Do it by mileage or months based on the type of driving you will do and you can’t go wrong.
