It's me again with another question. What about fuel additives for 15 diesel? I know ford sells some and XDP has one that everyone raves about. Is this necessary and if so when? By when I mean higher mileage or start when brand new like mine? Thanks for any info

If you live where it's cold, sub freezing, you should already be using additives. PM22a(pm23a for winter )is what I'd use if I was under warranty.
