Ran half a tank (15gal) of B-20 (20% bio / 80% dino) through my 1984 Chevy P30 Stepvan that was repowered back in '85/'86 with a White-Hercules DT3.7 (Inline 4cyl turbo). Truck ran great. Didn't read previous posts, but for more information on biodiesel, they have a website: http://www.biodiesel.org They have a 'where biodiesel is sold' area.


Only drawback is the price:


Regular diesel: $1.779


Biodiesel 20% (B-20): $1.949


Rymes Heating Oil sells B-20 at their pump in Antrim, NH where I bought my 15 gallons. I think the other million stations they have sell it too.
