well we will see, I obviously and having no luck talking the new owners out of it, despite me quoting reliable sources.

I  don't think anyone doubts or disputes the environmental benefits, but the only places I see that are willing to state mechanical benefits are Bio Diesel organizations.  Have not found any college studies stating anything about it's mechanical benefits.

Note the engine in the bus is a 70k mile from new 6-71

MC-8, HMMM, I am getting my info from Several Biodiesel promoting organizations in the states.

from the looks of your volkswagon list that was a European site as alot of those models are not sold in the US.

Bio D in Europe is much more strictly regulated , read refined better across the board, than in the US.

the US Volkswagon site says Volkwagon only supports the use of B5.........

"In summary:


Volkswagen recommends the use of standard diesel fuel or commercially supplied biodiesel blends of no more than five percent ("B5") biodiesel.
Never use any fuel, whether diesel, B5 biodiesel, or otherwise, that fails to meet the latest petroleum industry specifications or that is not purchased from a commercial retail diesel pump. If you are unable to determine whether a particular fuel blend is B5 biodiesel that meets the latest biodiesel industry specifications (ASTM D6751), ask your service station for more information.
Never use any fuel for which the contents cannot be identified"
