There are some disadvantages of gasohol. Alcohol-based fuels typically require more fuel to produce the same power output of more traditional gasoline. They also have a low boiling point, which can create problems with vapor lock in vehicles on a hot day. This problem can be more serious at high altitudes, so be careful if you are driving in the mountains. Separation of the fuel and alcohol is also possible, which can produce significant power reduction. This condition is more likely to occur in cold temperatures. There have been concerns raised about the amount of energy required to raise the grain to make alcohol-based fuels. It also pulls a significant amount of grain out of the world's food network.
