I was alittle disappointed when I saw the 6.7 come out with a badge b20 on the side. I figured just like Vw and other companies using a dpf filter and using anything over b20 would clog the filter. It would be great to see the big truck able to run on b100, vso, etc. everyone knows Americans eat a lot of fried food so why can't we help and reuse the cooking oil. I sure there is away ford can make this happen. And if thy did and decided to bring electric to the equation who knows what the diesel truck can accomplish.
