The only issue I am aware of I got second hand, on this site... Bio-D is far better at lubricity... In nearly any concentration it improves any diesel fuel well above the lubricity specs of all diesel injection pumps. The hpvDiesel renewable whatever... Is smooth, and inexpensive, but nowhere near as lubricious... So, that should qualify as a point where it is not "far superior in every way"...

That said... I really wish it was available here.
