In here in western WA there is B99 in Seattle (dedicated biodiesel only fuel station). But I use biodiesel fuel very rarely for several reasons, some mentioned by another forum membersI've run B20 all the way up to B100. I personally prefer B100 over diesel, but it is hard to get in my area (state of TX
One word of caution, biodiesel (especially B100) is an effective paint remover, if you spill it on your paint, clean it off imediately.
a) B99 here is considerably more expensive than regular #2 diesel
b) that B99 is like acetone towards rubberized underbody coating or even when on fuel tank rubber coat, one splash or leak and rubber coating is destroyed in area or leak
c) my truck sits a lot more than driven, and leaving B99 in fuel tank will lead to fungi, rot and clogged pump
Other than that, my 85 6.9 runs fine on B99, no obvious difference.
PS. Honestly I don't know how, given the solvent-like nature of biodiesel, B99 can rot and fruit fungi etc.
