I suppose I must have put this question in the wrong forum topic.

Does anyone know where to get this grade in the triangle / triad area ?

 

Well, a year or so ago when I was researching CNG filling and hydrogen filling, I came across a ULSD bio-fuel in greensboro, I think down near Southeastern area of Greensboro kinda close to I85 somewhere. It was like a place that sold heating oils and so forth. But now I can't find them at all. Unfortunately, I can't recall if it was B15 or B5 either. I'll keep looking, but I'm not finding any of the helpful websites I used last time. Its like they're not at the top of the search list anymore.
