Just wondering what everyone uses in their truck.

All the choices for

Diff's, Transmission, Transfer Case, Oil blah blah blah....

I like Royal Purple and use it whenever possible.

Mobil1 5w20, Mopar ATF+4, Mopar coolant, Mopar friction modifier with Mobil1 in the diffs.

I've tried a few different oils but it seems to be the quietest with mobil1 5w20. It seems like I do a cam swap ever 2k miles so it gets changed alot. lol

man honestly i have nver done much thinking about what oil to use usually what ever the dealer dumps in there is what i run. but like speedly said my motor gets ripped apart so often and the oil gets changed so much that it really is not an issue.

Mobil 1 5/20 and Mopar fluids for everything else. Walmart has them plus the Mopar oil filters. Buy the tranny filters from Dodge dealer. My hemi uses no oil at 101,000 in my Ram nor does the one in my 146,000 RT Magnum. In fact, I'm putting a FRI Sidewinder cam in my Magnum and can't believe how clean the hemi is inside!
