What will happen if I use flex fuel?
Flex fuel, also known as E85, is a blend of gasoline and ethanol, typically containing up to 85% ethanol. It is designed for use in flexible-fuel vehicles (FFVs), which are specially engineered to run on both regular gasoline and ethanol blends. But what happens if you use flex fuel in your car? Let’s explore the potential outcomes and considerations.
Understanding Flex Fuel and Its Compatibility
Flex fuel is not suitable for every vehicle. It is specifically designed for FFVs, which have engines and fuel systems capable of handling higher ethanol concentrations. If your car is not an FFV, using flex fuel can lead to significant issues. Here’s what you need to know:
- Engine Compatibility: FFVs are equipped with sensors and components that can adjust to the ethanol content in flex fuel. Non-FFVs lack these features, which can result in engine damage or poor performance.
- Fuel System Impact: Ethanol is more corrosive than gasoline. Non-FFVs may experience damage to fuel lines, seals, and other components if exposed to high ethanol concentrations.
- Check Your Owner’s Manual: Always refer to your vehicle’s owner’s manual to confirm whether it is compatible with flex fuel. Look for labels or markings indicating FFV capability.
Using flex fuel in a non-FFV can lead to costly repairs and reduced efficiency. It’s crucial to ensure compatibility before filling up with E85.
Benefits of Using Flex Fuel in FFVs
If your vehicle is an FFV, using flex fuel can offer several advantages. Here are some of the key benefits:
- Environmental Benefits: Ethanol is a renewable resource, and flex fuel produces fewer greenhouse gas emissions compared to regular gasoline.
- Cost Savings: Flex fuel is often cheaper than regular gasoline, which can help reduce fuel expenses.
- Energy Independence: By using ethanol, you contribute to reducing reliance on imported oil and support domestic energy production.
These benefits make flex fuel an attractive option for FFV owners, especially those looking to reduce their carbon footprint and save money at the pump.
Potential Drawbacks of Flex Fuel
While flex fuel has its advantages, there are also some drawbacks to consider:
- Lower Fuel Efficiency: Ethanol contains less energy per gallon than gasoline, which can result in reduced miles per gallon (MPG).
- Availability: Flex fuel is not as widely available as regular gasoline, which may limit your options depending on your location.
- Cold Weather Performance: Ethanol can make starting your vehicle more difficult in extremely cold temperatures.
Weighing these factors can help you decide whether flex fuel is the right choice for your driving needs and circumstances.
Conclusion
Using flex fuel in your vehicle can be beneficial if your car is an FFV, offering environmental and cost-saving advantages. However, it is essential to ensure compatibility before using E85, as non-FFVs are not designed to handle high ethanol concentrations and may suffer damage. Always consult your owner’s manual or a trusted auto service professional if you are unsure about your vehicle’s compatibility with flex fuel.

Frequently Asked Questions
What happens if you mix E85 and regular gas?
realistically it's completely fine. the 02 sensor readings are going to be off as e85 burns at a different ratio then normal fuel. your best bet is to drive it gently or normal, not beat on it, and just dilute it and it'll be just fine.
Is it a good idea to buy a flex-fuel?
There are no benefits to using it, in fact it's worse for gas mileage than regular gas. It's also not good to switch back and forth often or mix them. If you put E85 in the tank you should stick with it. The only reason we even have that crap is because of government sweetheart deals and corn subsidies.
Will flex-fuel damage my engine?
E85 is actually safer for your engine than regular gasoline is. E85 flex fuel not only powers your engine but also cleans your engine, fuel lines, and fuel injectors. That's because E85 contains a high amount of ethanol, up to 83%. Ethanol is an excellent cleaner.
What happens if I use flex-fuel in a regular car?
- Engine Damage: Non-flex fuel vehicles are not designed to handle the high ethanol content found in flex fuel.
- Poor Performance: The higher ethanol content can cause the engine to run poorly, resulting in decreased power, reduced fuel efficiency, and potential stalling.
What if I accidentally put E85 in my gas tank?
In some cases, using the wrong fuel is harmless. Other times, like if you accidentally put E85 fuel in a car that's not designed for it, you can void your engine warranty or cause costly damage to fuel lines. The price to fix a car from a fueling mishap can be steep, but there's no reason to panic.
Is it bad to put 87 in a flex fuel vehicle?
Using any octane level of gasoline in a flex-fuel vehicle is acceptable. The sensors in an FFV detect whether the fuel is pure gasoline or 85% ethanol and make necessary changes for optimal fuel injection and timing of combustion. Putting E85 in a car not designed for flexible fuel can be harmful.
Is it OK to switch between E85 and regular gas?
Using any octane level of gasoline in a flex-fuel vehicle is acceptable. The sensors in an FFV detect whether the fuel is pure gasoline or 85% ethanol and make necessary changes for optimal fuel injection and timing of combustion. Putting E85 in a car not designed for flexible fuel can be harmful.
Can E85 damage my engine?
Much greater risks occur when E85 is used in a non-flex-fuel vehicle over time. Continually filling a standard gasoline car with this high-ethanol fuel can result in serious fuel system corrosion. Plus, when you accidentally put E85 fuel in a car, it may void your engine warranty.
What happens if you accidentally use flex-fuel?
- Engine Damage: Non-flex fuel vehicles are not designed to handle the high ethanol content found in flex fuel.
- Poor Performance: The higher ethanol content can cause the engine to run poorly, resulting in decreased power, reduced fuel efficiency, and potential stalling.
What is the downside of flex fuel?
The cons of flex-fuel vehicles are that they have less mileage, have an effect on crop economy, and have limited availability. In an emergency, you can put standard gasoline in your flex-fuel car.
