lugh said:Thanks to both of you. That's good to hear. We are waiting for the only known (by us) supplier on Long Island of bio to get his butt over and set us up with a holding tank which he is supposed to keep filled (sort of like an oil tank to heat a house). Then, we will be filling up from our own reserve and can run it 100, 95 or whatever we want. Looks like it will be better than diesel and cheaper, too.
