E-85 vs Distillate

Has anyone tried using E-85 on the old dual-fuel tractors such as a F-20? It seems it should work to start on gas and run on E-85.
 
It will run, it will not make good power, the e85 can handle 9.5 or higher compression, the distillate will have about 1/2 of that. not wrong, just not advantageous. It would take a propane head, and a opening of carb jets as well as som distributor recurve to make it function like it was designed for E85. JimN
 
Really no need to start on gas UNLESS it is really cold. They start and run on E85, done it for several years. Check all the sediment screens and make sure fuel lines and carb are rust free or they will be after a tank or two.
 
In eastern Nebraska, we called it "Tractor Fuel" and it seemed lighter and lower octane than gasolene. I am just trying to save a few dollars on fuel for my "H.O. Farming" by using a cheaper fuel. Perhaps, I may be penny wise and pound foolish!
 
Don't know much about E-85, but it appears from what people are saying here that it works with high compressions. I grew up with several "kerosene" or K-D tractors (10-20, "Regular," F-20, H) and nobody I knew was using kerosene or distillate anymore after maybe 1935. It's just too much trouble (start on gas, warm up to HOT or it won't run right, keep it HOT, shut off fuel to stop, etc.). Gasoline in those low-compression engines (a little over 4 to 1, probably) works just fine, but it is certainly not going to bring the power you'd get with compression around 6 to 1, which is what I think it would have been once you could buy an engine specifically for gas (like with F-12, F-14, H and M, etc.).
