Just purchased new 3500 w/Cummins engine,was wondering what weight and brand of oil to stick with.I'm leaning towards a synthetic such as Mobil 1,but I know that alot of guys here use the Amsoil brand.Also wanting to find out aftermarket fuel and oil filter numbers in place of Dodge/Mopar filters. Thanks for any info.Love this engine,just don't know anything about them yet!! PW content-I'll be spending less time working on the WM300 while I learn about the Cummins!
