Oil recommendation for Pentastar V6 after valvetrain replacement

[EBruce]

Mobil 1 ESP 0W30 or 5W30 would be my pick.

I agree, I switched my 2019 Jeep GC 3.6 V6 to Mobil1 5/30 after warranty and it works fine. I noticed it is much quieter on start up and oil temp is about 5 degrees cooler. These engines have been aroud a long time and are still using 0/30 5/30 and 0/40 in other countries. I also stick to the 20% on the oil indicator or 5,000 miles OCI. It has been 15.000 miles now and no worries.
