I'll be the first to admit that I buy the diesel (petro or B5,B10,B20) that is cheaper per gallon....when your running through the stuff like there is no tomorrow every gallon counts. Three days ago I went and filled up with dinodiesel at $3.21 a gallon...the only place in town that carries and bio-diesel (who had been 10-12 cents higher than everyone else for a couple of months) had it for $3.19. That is what get for not keeping an eye on what they are charging for B20. I wish there was a tax break for running bio-diesel....say at least B10, with the exception of the supertanker owners & OPEC...everyone would benefit from bio-diesel in my mind; but then we're talking about a scary place.
