I am on my 1st fill of M1 0w30 and this engine seems to really agree with it. Previous fills were PYB 5w20 and VWB 5w20. I dont agree with Chrysler's change from 5w30 to 5w20 in the '07 MY...CAFE I'm sure. I think the biggest factor though was the NG 1515 filter; it is literally an inch taller than the stock NG 1085/MO-090.
Interesting info, thanks!
I agree Chrysler's jump to 5w20 seems more CAFE driven to me than anything else.
My "cold" start ups through out the winter will generally be in the 20's and 30's F. I think an 0w30 may actually be thicker at those temps than some 5w30's, but I'll have to look into that if what I'm trying now doesn't work.
Note on M1 0w30...in our 4.0 it made more than twice the iron of any other oil tested....flat tappets...
Oh yes, Mobil is not even on the table for the Jeep. I've looked at the Castrol 0w30 but haven't bit on it yet.
