Calm down gentlemen. Let me take you back to the alcohol fueled cars of my old race days. Tuned right, it is the best performance fuel for certain activities. You will not get the mileage though. The only drawback to E85. Many were converting to E85 for performance, but fuel economy will suffer 20-30%. Again, I heard this same complaining when leaded was taken away from my old muscle cars. But, somehow we managed to survive. As far as corn shortages, well, that isn't going to happen. Our US farmers are for the first time in decades making some money for their products. Ethenol being one of them. We genectical alter the corn just for selling to the fuel market. Just like we genetically alter corn for the food market. Soybeans are fueling the trucking industry as well. We heard complaining from them, but over time, engines makers have adapted, and so will the car engine builders... It, alcohol, burns hotter....and faster, and so, just like tuning, for certain racing, they will tune, and build injectors for whatever the blend will be. I'm not worried about it. Keep in mind, most engine come rated for what they should be burning...many think moving up to higher octane than what the engine is rated for, gives them better performance. But, sometimes, depending the motor, tuning, etc, that isn't always true....
I might add, the EPA scares me more, especially the new restrictions being put on engine builders. Catapillar has already pulled out of the trucking industry. They no longer will build engines for the big rigs. Cummins, is on the bubble as well...soon, there won't be a competive market for those engines...then look. Is the auto industry next? EPA needs to get a life. Global warming my ***, as Indiana broke record heat temperatures that were set back in 1898. I guess global warming was a problem then too....lol....
