I am chiming in late on this, but in my 2006. I get a slight tick at start up, only when using the 5w20. When I use the 10w30, it does not do this. This is a 2006 2500 Ram. They dont get the MDS because they are work trucks. I asked the dealer and he told me they use 10w30 in all the Non-MDS Hemi's since we are in Florida, it wont hurt a thing. Id try the 10w30 on your next change, it wont hurt.
