There is a police supplement for the patrol cruisers and it actually indicates using 10w-30 is acceptable grade.
I have scene a couple of local cruisers at the Dodge store while visiting my pals who are techs and they had the top ends apart with bad cams, cruisers had 100k miles+ on em. The hemis were clean inside and I was told they ran LCD bulk 5w-20. So maybe in their application with tons of idling and pursuits, maybe a thicker oil would help the cam lobes.
Looking at the manual actually states 10w-30 mobil 1, this upfitters police manual is circa 2011.
