In my opinion every engine produced today, and in the last 10 years, should be able to run on E-85 Ethanol. Everybody is pushing using the stuff, but nobody wants to produce an engine to use it because it will add an addition $50-$100 per engine. There are few engines that you can get that run on E-85. When I bought my '05 F150 King Ranch, I couldn't use E-85 in it because I had the 5.4L that came in the KR. If I would have ordered a F150 Lariet with the 5.4L then it would have been able to run E-85. Now who is making those rules??? I would love to help out the Ethanol producers here in America and support my local farmers, but if the automanufactures don't get it together and start producing vehicles that run on E-85 then why are we building all these Ethanol plants and spending money on researching ways to produce Ethanol cheaper and easier on the enviroment.
My wife and the local cops laugh at me now that I am driving my 1969 Harley Davidson Golf Cart around town. I rebuilt it last winter to use on the golf course and drive back and forth from the course (all 6 blocks). Now with gas prices I am in the process of getting it certified as a Neighborhood Vehicle, or slow moving vehicle, so I can drive it around town. From my figures I am getting close to 50 mpg from the 12 hp Briggs that I put in it, and that's at 20+ mph. Just a good thing that I live in a small town.
