I believe the recommended oil type was changed last year, I want to say it is 5w-30 synthetic but just research well on google. Sorry for the ambiguity. I just get the mopar filters on amazon.
Hi.
They have crank bearing issues so Jeep changed the oil spec. The new spec calls for a heavy duty diesel engine oil. E9 is the euro spec and i think CK4 is the US spec. They also went from 5w30 to 5w40.
Been using the same filter since we bought ours. Here is the product Oil Filter - 5281090AB | JeepsAreUs | Jeeps Are Us. It's just a mopar basic filter that last longer compared to when we tried a cheaper brand.
