Just thought that I would pass along this in case there is someone thinking of making bio, or just for comparison.
My last batch I figure to cost us about $.97 / gallon to make - used 1/2 of methanol as recovered from previous batches. Adding Magnesol in at my cost figures to be about $.19 / gal for a total of $1.16 / gallon. Can't complain about that when Diesel here is $2.23 / gallon.
