My Demon 170 has almost 500 miles on the odometer. The car arrived with a full tank of E-10. The dashboard display accurately confirmed the presence of E-10. How do I know? I was the one squeezing the nozzle on that initial fill. Since then I have run several tanks full of E-85 from QwikTrip. The inclusion of their E-85 finally topped out as E-59 on my display. This mystery was quickly solved when I went onto their website. Here is what I found:
E-85 fuel contains 51%-85% ethanol and the rest gasoline....

With E-59 the horsepower is capped at 1010.
