I think I'll dump in 7qts 5W30 and see what happens. I don't think anything will happen. We'll see. The oil of choice is NAPA synthetic.
I have to admit, its more complicated when it comes to the Hemi and MDS, I have the Flex Fuel 4.7 with no MDS, so I am not affected by the MDS having issues if higher viscosity's are used.
