We run B100 in our '03 TDI and B50 in our '82 240D. Our results are basically the same as yours, but I think we've had low to no drop (0 to 10%) in mileage on B100 in the late model TDI; anecdotally, the older the engine (or design thereof), the bigger the drop in mpg going to biodiesel - any hypotheses, folks?
