Default

only the Ram 1500 has MDS & use the 5w20
the 2500 & 3500s don't have the MDS & those engines use 10w30
both are the exact same short block

you really have to understand the MDS system & how it closes off the 4 unused cylinders to really understand why the lighter weight oil is used for the MDS
it is way to technical for me
