Off-roaders like clean air as much as anyone else. To that end, Kurt is busy tuning the engine to run of Ethanol E-85. He points out several advantages: "E-85 has been proven to reduce tailpipe emissions over fossil fuels, has a much higher octane rating (105) and contains no lead as racing fuels do...E-85 is running $2.49 a gallon at a local station. Even though E-85 requires 25 to 30 percent more fuel to produce the same power figures, it still makes much more sense than burning leaded racing fuels, which currently run around $10.00 per gallon."
