I was surprised to read that you feel you get better mpg on Bio-D than on regular ULSD. I just assumed I would lose mpg like you do using E-85 in a gasser.

It surprises me too. I have not done an A-B-A, but it would be very easy to do once the weather warms. At the moment all my fuel logs show it, but you cannot separate the seasonal effects from the logs. But it looks consistent, my higher blends typically show 2-5 mpg better on high biodiesel percentages. I attribute the higher cetane numbers of the bio as partly responsible, as ULSD I think is running at the low end of 40, and it has less energy in it than the old LSD. I would bet the energy content of biodiesel is now nearly equivalent to ULSD.
