well since I live in the deserts of Dubai,
I'll be sticking to what the dealer offers to avoid voiding my warranty
3yrs or 60K Kilos
they use Mopar Semi-synthetic 5w20, after that I'm going 5w30 full synthetic to test it. if I don't like I will switch to 5w20 full synthetic
if I like it I'm sticking to it.
and will update you all
But FYI, both 5w20 or 5w30 won't hurt, manual from here attached with MDS
