Fuel Freedom Foundation has a lot of irons in the fire. Sure, we spread the word about the benefits of fuel choice on our witty, informative social-media channels, our awesome 2014 movie PUMP (Jason Bateman! OMG!!), and our exhaustively comprehensive but hugely entertaining website.

But we’ve also been busy testing a car in Colorado in an effort to prove to the EPA that it’s possible to convert a gasoline-only car to run on E85 ethanol blend, with only an update to the vehicle’s on-board computer.

We also underwrite research at major universities and think tanks on a variety of issues related to our overall goal of creating fuel choice at the pump. For instance, Prof. James D. Hamilton at the University of California at San Diego wrote a paper showing that 10 of the last U.S. recessions since World War II were preceded by a spike in oil prices. He added that “there is a significant likelihood of repeating that experience within the next 5 years.” Um, that paper was written in 2012, y’all.

Showing that car conversions are feasible is a crucial goal, because millions of American cars might be eligible. There are about 17 million flex-fuel vehicles on the road, capable of running on any mixture of ethanol and gasoline. Millions of other FFV “twins” are around, built at the factory to run on E85 but just needing the software to be optimized to do so. And as Miles Light, an economist at the University of Colorado’s Leeds School of Business, wrote in a paper:

46.9 million conventional fuel vehicles can potentially be converted for $150–$250 each. In all, this represents 77.75 million light duty vehicles, or 31.8% of the national light duty fleet, that would potentially purchase natural gas liquid fuel, if prices were attractive.

Ethanol isn’t the only alcohol fuel that could help us reduce our dependence on oil. A forthcoming study by the MIT Energy Initiative says methanol can improve engine efficiency. An early version of the study states:

Higher engine performance (mostly described in terms of efficiency in this report) can be achieved by intrinsic properties of the fuels, as described above, with no changes to the operation of the vehicle. Or it can be obtained by using different software in the computer, adjusting the parameters (such as spark timing and valve timing), which requires re-calibration of the engine.

Fuel Freedom can’t make fuel choice happen without you. Sign up on our Take Action page to join the fight and receive updates on our progress. And if you’re so inclined, you can donate to our cause so we can keep going with our research and car-testing initiatives.

Americans deserve to drive for less!
