*12+ horsepower hours per gallon of gas according to Nebraska tests, one of the more efficient gas tractors since the first test. At stock horsepower and full load, it's gonna be a high volume of fuel, 5 gallons an hour if my math is right. MBHP divided by HPhrs per gallon is what I used. Furthermore, a 656 diesel is rated around *12.5 HPhrs/gal, meaning they're about the same efficiency under full load--although Hugh MacKay always said his 656D would do 2 gal/hr pulling 5 bottoms (canada vs usa gallons imho). Every individual tractor is different so there are variations either way from the test tractor's results and the individual tractors' observed performance.
FWIW, a C farmall is in the 10 or 11 HPhrs/gal family, less efficient, but at its hp, the gallons per hour are not very much.
If you are after efficiency under full load, go diesel and much newer. If you need to stay older, borrow C H Wendel's Nebraska Tests (thru 1984) and look at the index in the back where it ranks efficiency by fuel type. There is probably a resource online for the newer stuff as well.

ps I've been reading the Wendel book this week. The most memorable thing I have read: is a bigger (115 hp area) tractor that is very efficient is the Case 2096 at 17+ HPhrs/gal.
(edit: * = numbers not accurate)

Today's Featured Article - Uncle Cecil's Super A Lives Again - by Mike Purcell. A week or so out of most of my childhood summers was often spent with my Uncle Cecil and Aunt Sissie in the small East Texas town of Maydelle on their 80 acre farm. Some of my fondest memories of these visits are those of learning to drive a tractor at the helm of Uncle Cecil’s 1948 Farmall Super A. Uncle Cecil was the second owner of this wonderful little tractor, but it was almost as though he had adopted an infant. The original owner was a man from Minnesota who bought her from a local dea
