As an automotive expert with extensive experience in the field of automotive fuels, I have often been asked about the use of ethanol in vehicles. Ethanol, a type of biofuel, has been increasingly used as a gasoline additive or as a standalone fuel in flex-fuel vehicles. It is derived from various sources such as corn, sugarcane, and other plant materials. The use of ethanol in cars can be a complex topic with various factors to consider.
Ethanol as a Fuel Source:
Ethanol is considered a renewable fuel, which is an attractive quality in the context of environmental concerns and the need for sustainable energy sources. It can reduce greenhouse gas emissions compared to traditional gasoline, making it a more environmentally friendly option. Additionally, using ethanol can contribute to energy independence by reducing reliance on imported oil.
Gas Mileage Concerns:
One of the primary concerns with ethanol is its impact on fuel efficiency. As you mentioned, The New York Times reported that E10 gasoline, which contains up to 10% ethanol, can result in a 2-3 miles per gallon decrease in fuel economy compared to pure gasoline. This is due to ethanol having a lower energy content per gallon than gasoline. E85, a blend that consists of 85% ethanol, is even more significant in terms of fuel economy reduction, with a loss of 7-8 miles per gallon. This reduction in mileage can be a considerable drawback, especially for drivers who prioritize fuel efficiency.
Engine Compatibility:
Ethanol is hygroscopic, meaning it attracts moisture. This can lead to issues such as corrosion and the formation of rust in the fuel system, which may not be compatible with older engines not designed to handle ethanol blends. However, modern vehicles are generally designed to handle ethanol blends without significant issues.
Performance Considerations:
While ethanol may reduce fuel economy, it can also offer some performance benefits. It has a higher octane rating than regular gasoline, which can lead to better engine performance and potentially reduce engine knocking. This can be advantageous for high-performance vehicles or those that require a higher octane fuel.
Infrastructure and Availability:
Another aspect to consider is the availability of ethanol-blended fuels. E10 is widely available in many countries, including the United States, but E85 is less common and may not be accessible in all areas. This can limit the practicality of using ethanol as a primary fuel source for flex-fuel vehicles.
Economic Factors:
The cost of ethanol-blended fuels can also vary. Sometimes, it may be more economical than traditional gasoline, but this can fluctuate based on market conditions and the cost of producing ethanol.
Environmental Impact:
While ethanol is often touted as a cleaner fuel, its overall environmental impact is a subject of debate. The production of ethanol can have its own environmental costs, including land use changes, water consumption, and the potential for increased greenhouse gas emissions if not managed sustainably.
Conclusion:
Whether ethanol is "good" for your car depends on a variety of factors including the type of vehicle you drive, your driving habits, the availability of ethanol-blended fuels in your area, and your personal priorities regarding fuel efficiency, performance, and environmental impact. It's essential to weigh these considerations carefully when deciding whether to use ethanol as a fuel source for your vehicle.

Some gas stations offer a new fuel blend containing 85 percent ethanol to 15 percent gasoline, called E85 or flex fuel. This ethanol blend is only for vehicles specifically designed to use it, and in a non-Cflex fuel vehicle it could cause the engine to stall.
