Ok, I've been all over the forums and cannot find exactly what I'm after...I know this from the manual and forums

Front Lube 75W90 Lube
Rear Lube 75W140 Lube (friction modifier required if not using synthetic w/ LSD)

I'm looking at the Royal Purple stuff..

Question is "how much of which?"

 

You'll need 3qts. for the rear You'll use 2.25qts+/- or 3.5pints as Chrysler states. Royal Purple states you don't need Additiives with their oils but i would add the 4oz required anyways.

Front will need 4.8pts or 2.4qts

 

On my 2WD Hemi w/LSD I added the PML polished cover for extra fluid capacity and used Royal Purple 75W-140 'WITHOUT' the additional additive as indicated by RP and have not had any problems.

 

I have RP and havent used the additive either and have had no issues either.
