I am new to this forum and basically to the diesel world. I just bought a 99 f 250 and I am curious about the fuel types I live in Iowa so my guess is that the fuel is blended in the winter.
My, probably dumb, question is which fuel do I want to run most of the time.
I have read that the d2 has more lubrictiy so that sounds like the right one
the manual for the truck recomends either d1 d2 with no explanation of quality or benefit from either
Is one better for my truck than the other?... what are the up-sides and down-sides of each.
thanks. dg
