You mention in your response to this question that you actually want to know what the disadvantages and advantages of Gasahol are. The gasoline and alcohol mixture is one that can be used as an alternative fuel. Producing and using gasohol has both its advantages and disadvantages that affect users and the environment. Using gasohol in vehicles is encouraged in the United States, particularly where corn is used to produce ethanol locally.
One of the advantages of using a fuel blend such as gasohol is that they tend to have a much higher octane rating. Higher octane ratings mean that the fuel tends to burn in a controlled manner, rather than exploding in an uncontrolled manner. High octane ratings are particularly important in unleaded fuel so using gasohol is an efficient way to guarantee the fuel has a high octane rating. Using gasohol is also advantageous as it reduces the amount of carbon emissions released by the car, it ‘leans out’ the fuel mixture. The reductions can be as much as 17 per cent for carbon monoxide emissions and 4.2 per cent for carbon dioxide emissions. Reducing carbon emissions has a positive impact on the environment and is something that is being encouraged all over the world.
The primary disadvantage of using gasohol, and many other fuel blends, is that in some conditions the alcohol and gasoline may separate. In circumstances where this happens, the engine is unable to produce as much power from the alcohol if it is programmed to burn gasoline efficiently. As the temperature decreases and causes the mixture to separate, the amount of water that is absorbed increases and the quality of the gasoline decreases. While gasohol reduces the amount of carbon emissions from a vehicle, it has the disadvantage of releasing other toxins instead. Nitrogen oxides, volatile organic compounds and aldehydes are all increased with the usage of gasohol.
