What is the best Oil And Fluid To use on my 7.3L?

To keep your 7.3 running strong, we recommend using OEM fluids for just about everything. There is a little bit of flexibility with engine oil. You may need a different viscosity if you are in extremely cold climates. You do not have to go with Motorcraft 15W40 however. There are many good 15W40 engine oils made specifically for a diesel.
