I'm not sure what you mean. Are you talking about the old stationary engine I have that burns a mixture of fuels? If so, it burns Kerosene and E-10, 1:1 in the winter and 2:3 in the summer. The second best mix for it is diesel and E-10 mixed 2:3, if I remember right; but I haven't run on that in several years. It's not as flexible under varying loads.
The question was whether anyone else has found E-10 to run better in their Deeres than gasoline without ethanol.
