Sorry to double post at you, but I went looking for some stats myself after I asked my previous question and I am finding quite a wide variation in the answers. One site showed the following as stats:

Gasoline: 1 Gal Gasoline (mid grade) = 125,000 Btu's Ethanol: 1 Gal Ethanol = 76,000 Btu's

Another showed the difference to be less than 4,000 Btu's. So I guess we have a wide range of opinion on how much work one can get from a gallon of regular unleaded gasoline vs. a gallon of ethanol (10%).

125 is a good number. N2FO can be 130-135. Reclaimed lube oil at 25 API is about 138-140. My biz is in the heavies (a man’s barrel.)
