Flex fuel, also known as E85, is a blend of gasoline and ethanol, typically containing between 51% and 83% ethanol. Here are some reasons why flex fuel is considered to be better than gasoline:
Renewable energy source: Ethanol is made from crops such as corn or sugarcane, which can be grown and harvested annually, making it a renewable energy source. This means that the production and use of ethanol as a fuel can help reduce dependence on non-renewable fossil fuels such as petroleum.
Lower greenhouse gas emissions: When compared to gasoline, ethanol produces lower levels of greenhouse gas emissions, including carbon dioxide and other pollutants. This is because the production of ethanol requires less energy than the production of gasoline, and ethanol burns more cleanly than gasoline when used as a fuel.
Improved engine performance: Flex fuel engines are designed to take advantage of the higher octane rating of ethanol, which can lead to improved engine performance and increased horsepower. Additionally, ethanol has a higher heat of vaporization than gasoline, which can help to cool the engine and reduce engine knock.
Cost savings: In some areas, flex fuel is cheaper than gasoline. Additionally, since ethanol is produced domestically, using flex fuel can reduce dependence on foreign oil and help to support local economies.
It's worth noting that flex fuel does have some drawbacks, including lower fuel economy and a limited availability of fueling stations in some areas. Additionally, the production of ethanol requires a significant amount of water and other resources, and the cultivation of crops for ethanol production can lead to deforestation and other environmental issues if not managed sustainably.
Overall, flex fuel is considered to be a better option than gasoline due to its renewable energy source, lower greenhouse gas emissions, improved engine performance, and potential cost savings. However, as with any fuel source, it is important to weigh the benefits and drawbacks and make an informed decision based on your individual needs and circumstances.
