Fisherman-I have run a fuels testing lab now for 25 years. We have done every test known to mondern man on engine fuels. Don't worry about doing E10 plus E85 blends. E10 is 10% ethanol in gasoline. E85 is 85% ethanol in gasoline. Yes, E 85 is hard to start on, but a hotter spark from a higher output coil would end that problem. Hotter plugs will help too. As a part of the creation of RFG gasoline , which is simply a mix of 10% oxygenated gasoline sold to reduce emmissions near the big cities, we did many different addition level studies. In addition to bench tests we did engine tests and gasket tests. When all was said and done , the old tractor engines and systems can tolerate a lot more than you think.You are not dealing with a whole lot of engineering sophistication. Some gaskets such a buna, viton , etc. are better with alcohols, but I have never really encounter problems at around the 50% blending range. Bear in mind that the ethanol BTU value is less than that of gasoline and that will affect mileage,but by and large the reduction in mileage is related to the amount of the blend. Also it varies from engine to engine.
