As an automotive expert with years of experience in the field, I can provide you with a comprehensive answer to your question regarding the effects of using ethanol in a gasoline-powered vehicle.
Ethanol, commonly known as ethyl alcohol, is a biofuel that can be blended with gasoline to create what is known as E85 fuel. E85 is a mixture of 85% ethanol and 15% gasoline, and it is specifically designed for flex-fuel vehicles (FFVs) that are equipped to handle the higher ethanol content. These vehicles have engines and fuel systems that are engineered to operate efficiently with the varying ethanol-to-gasoline ratios.
However, if you mistakenly put ethanol into a gasoline-powered vehicle that is not designed to run on E85, several issues may arise:
1. Engine Knocking: Ethanol has a higher octane rating than gasoline, which means it can withstand higher compression before igniting. In a non-flex-fuel engine, this can lead to engine knocking or pinging, which is caused by the fuel igniting prematurely due to the higher compression ratio.
2. Reduced Energy Content: Ethanol has a lower energy content than gasoline. This means that a gallon of E85 contains less energy than a gallon of gasoline. As a result, your car's fuel efficiency will be reduced, and you may notice a decrease in your vehicle's performance and power.
3. Corrosion: Ethanol is hygroscopic, meaning it attracts and holds moisture. This can lead to corrosion in the fuel system, particularly in the fuel lines, fuel pump, and injectors, as these components are not designed to handle the corrosive nature of ethanol.
4. Fuel System Clogging: The alcohol in ethanol can dissolve varnish and other deposits that have built up in the fuel system over time. While this might sound beneficial, it can actually lead to clogging of the fuel lines and injectors as these deposits are broken down and released into the system.
5. Material Compatibility Issues: Some of the materials used in the fuel system of non-flex-fuel vehicles may not be compatible with ethanol. This can lead to swelling, softening, or degradation of these materials, which can cause leaks or other malfunctions.
6. Cold Start Problems: Ethanol has a higher vapor pressure than gasoline, which can make it more difficult for the engine to start in cold weather. This is because the higher vapor pressure can lead to vapor lock, where the fuel line fills with vapor instead of liquid fuel, preventing the engine from starting.
If you have accidentally filled your non-flex-fuel vehicle with E85, there are steps you can take to mitigate the potential damage:
- Top Off with Regular Gasoline: The most immediate action you can take is to top off the fuel tank with regular gasoline. This will dilute the ethanol content and help to prevent some of the issues mentioned above.
- Run the Engine: Driving the vehicle for a short period can help to burn off the ethanol and clear the fuel system of any moisture that may have been introduced.
- Professional Inspection: If you are concerned about potential damage, it is advisable to have a professional mechanic inspect your vehicle's fuel system to check for any signs of corrosion, clogging, or material degradation.
- Fuel System Cleaning: In some cases, it may be necessary to perform a thorough cleaning of the fuel system to remove any deposits that have been loosened by the ethanol.
In conclusion, while ethanol can be a viable alternative fuel for certain types of vehicles, it is not suitable for all gasoline-powered cars. Always ensure that you are using the correct fuel type for your vehicle to avoid potential damage and performance issues.

Some cars, labelled as flex-fuel vehicles or FFV can switch between E85 and normal pump gas without any issues, but if you accidentally fill your non-FFV car with E85, you may notice some issues. ... So if you've accidentally put E85 into your gas car, top it up with regular gas a few times and ride it out.Jul 22, 2016
