‘23 is not the same 3.6l Pentastar thar’s in older models. Check the specs in your Owner’s Manual.

I see that 2022 is the same drivetrain as 2023.


What year did it change? What I am finding is that if there is any change it would because of oil quality upgrades from the oil companies over the years. It looked like 5W20 synthetic is factory fill but most prefer 0W30 to get better high temp operation in the RV applications.


Do you have a source on the difference between the engines by year?
