Did anyone check this engine option out at the GIE? What equipment might this be available on in the near future? Anyone with more info? This is rather exciting to me. Eth here is 20% discount to reg gas. Even at a 10% reduction in fuel economy, I would still come out ahead. I would gladly stop at the E85 pump down the street. Thanks Kohler for actually getting innovative and trying to keep up with the times.
