i still run this oil 7-9,000
Sure...
I have both in stash haven't used any 0/40 yet love the 0/30 here in MI,great cold weather or all year around oil seems smooth and no oil consumption in my GM vehicles,i think Chrysler specs 5/30? if you have no consumption i would say either would be a great fit,try the 0/30 see if it does anything for mileage for you i love the oil it seems thats what i always reach for.
