As a subject matter expert in automotive fuels, I'd like to address the question of whether ethanol in gas is bad for your car. Ethanol, a renewable fuel, has been blended with gasoline for decades due to its potential environmental benefits and its ability to reduce dependence on petroleum. However, the impact of ethanol on vehicles is multifaceted and warrants a detailed examination.
Firstly, the use of ethanol-blended fuels such as E10, which contains up to 10% ethanol, is common in many countries, including the United States. While this blend is widely accepted as safe for most modern vehicles, there are some considerations to keep in mind. The miles per gallon (MPG) reduction mentioned by The New York Times is a significant factor. E10 gasoline may result in a 2-3 MPG decrease compared to pure gasoline. This is primarily due to ethanol's lower energy content per gallon compared to gasoline. As a result, more fuel is required to achieve the same distance, which can lead to increased fuel consumption and costs for the consumer.
Another aspect to consider is the material compatibility of ethanol with various components of a vehicle. Ethanol has a different chemical makeup from gasoline and can cause corrosion in some engine parts, particularly in older vehicles not designed to run on ethanol-blended fuels. This is because ethanol is hygroscopic, meaning it attracts and holds water. When water is present, it can lead to corrosion in the fuel system and engine, potentially causing damage over time.
Ethanol also has a cleaning effect on the fuel system. While this can be beneficial in removing deposits and improving fuel efficiency, it can also dislodge debris that has accumulated over time. This debris can then clog fuel filters and injectors, potentially leading to engine performance issues.
Moreover, ethanol can affect the lubricity of the fuel. Gasoline naturally contains some lubricating properties, but ethanol does not. This can lead to increased wear on fuel pumps and injectors, although fuel additives are often used to mitigate this issue.
When it comes to higher ethanol blends, such as E85, which is used in flex-fuel vehicles, the impact is even more pronounced. E85 contains 85% ethanol and can result in a significant reduction in fuel efficiency, as noted by the 7-8 MPG loss compared to gasoline. This is due to the higher proportion of ethanol, which has a lower energy content. Flex-fuel vehicles are designed to handle these higher ethanol blends, but not all drivers may find the trade-off in fuel efficiency for the potential environmental benefits to be worthwhile.
In conclusion, while ethanol-blended fuels like E10 are generally considered safe for modern vehicles, they do come with some trade-offs, particularly in terms of fuel efficiency and potential material compatibility issues. For higher ethanol blends like E85, the impact on fuel efficiency is more significant, and these fuels are intended for flex-fuel vehicles that are specifically designed to accommodate them. As with any fuel, it's important for drivers to understand the properties and potential impacts of the fuel they are using and to maintain their vehicles accordingly.

One of the bad things that happens with ethanol is that your mileage will actually decrease. The New York Times stated that E10 gasoline, which is the gas we use in America, actually gives you 2-3 miles per gallon less than gasoline. E85 is a flex-fuel with 85% ethanol loses 7-8 miles per gallon.Feb 22, 2017
