it is biodiesel and petro diesel mixed you just put it in and go.

you have a 12v. run it. it wont hurt anything

Exactly what the others said, you're not going to hurt a thing in that 12v. You could burn used motor oil if filtered properly.
FYI. I run 100% biodiesel in my 05 CR, it's a great solvent for your fuel system.

I've heard that some car manufacturer uses cows' poop as fuel lol))) is that true?

B100 (100% Biodiesel) is all I run in my 12v.

Just pour it in and go. I'd carry an extra filter with you though. As mentioned it is a great solvent and will clean your system out, possibly clogging your filter.
