B20 BioDiesel
The Marathon in Apple Valley, MN is now selling B2, B20 and B100. This is the tank outside with B20.
To get the B100 you go to the service area and ask them to fill up your fuel jugs. They have it in their register as "Soy Oil" so you may have to ask for that. B2 is in the normal pumps on the island, and the B20 is this tank, with which you have to manually reset the counter before pumping, and then go inside and tell the lady (on your honor) how much you pumped.
My TDI is running smooth and happy! And the exhaust smells like Popcorn!

Nice! I almost wish we had bought a TDI Passat so that we could go the biodiesel route. I'm growing more and more convinced that biodiesel is an excellent idea.
I forget did you have to mod your car to make it run on biodiesel? How are the emissions?

No mods required for recent diesels. "Older" diesels may need some new fuel lines and such.
Emissions are better for particulates and some other things. Worse for NOx. I don't know all the technical details though.
