Welcome. IMHO your warranty is over, and I would move up to a 5-30 synthetic. If you want and you live where it's hot most of the year go to a 10-30. Also I would use a high mileage oil. I have an older SUV and this is what I did, with no change in oil pressure, temp or mileage. Just use a good product such as M1, Pennzoil, Valvoline or what I am using which is Shell Rotella for gas truck and SUV. It is 5-30 and I got it on Amazon. Also at Walmart.

thanks a lot for the advise !! I actually was thinking of getting mobile1 10w30 , I live in California so most of the year it’s always hit. So I believe I should go with 10w30.

Jeep specifically warns against the use of anything other than the 5W20 in these vehicles because any other weight messes up the MDS system calibration. I'd suggest listening to the people who designed it. If you want to maximize oil quality use your favorite synthetic oil.

Not clear why you'd stray from the manufacturer recommended oil weights. The manual doesn't say anything about changing specs as the vehicle ages.

The manual for my 2014 3.6L says use 5W20, or if that's not available, use 5W30. The manual also mentions for the Hemi, use only 5W20.
