I use Mobil1 full syn and Mopar filters.
If I'm correct because I'm not knowledgeable about 2500 hemi, would the heavier oil be because its an HD truck and would be put more strain on it hauling heavier loads, or should the half ton REALLY use 5w30 too but can't because the MDS so they settle for 5w20. Just a thought that's crossed my mind before.
