RE: I converted a glow engine to run on E85
Hi Capt'n,
E85 fuel consumption is less than glow fuel and more than gasoline. The difference between glow fuel and gasoline is almost a 2:1 difference with E85 falling in between them, probably closer to glow fuel than gasoline. On full size cars, there are differences between FFV's regarding the efficiency on E85. I met a guy last week that gets the same mileage on E85 as he does on gasoline on his new Ford F150. Maybe it wasn't very efficient on gasoline to begin with, and it is more efficent than the average FFV on E85, and the two things evened out his mileage on each fuel? Theoretically with the lower energy content of E85 it should take more volume to make the same power. We are at 6800'MSL up here so maybe that made his truck less efficient on gas? At the time, gas was 2.67/gal and the E85 was 1.99/gal so the difference to him is dramatic, on the order of spending 34% less on a fill-up for the same mileage.
