What is the downside of flex fuel?
Flex fuel vehicles, which can run on a blend of gasoline and ethanol, have become increasingly popular in recent years. However, there are some downsides to using flex fuel that consumers should be aware of.
Reduced Fuel Efficiency
One of the primary drawbacks of flex fuel is that it can reduce the fuel efficiency of a vehicle. Ethanol, the alcohol-based component of flex fuel, contains less energy per gallon than traditional gasoline. This means that vehicles running on flex fuel will typically get fewer miles per gallon compared to using regular gasoline.
Potential Engine Damage
Another concern with flex fuel is the potential for engine damage. Ethanol can be more corrosive than gasoline, and it may cause issues with certain engine components over time. This can lead to increased maintenance costs and a shorter lifespan for the vehicle's engine.
Limited Availability
Flex fuel is not as widely available as regular gasoline, which can be a significant inconvenience for drivers. Many gas stations do not offer flex fuel options, making it challenging to find a suitable refueling location, especially in certain regions. This can be particularly problematic for those who rely on their vehicles for long-distance travel or live in areas with limited flex fuel infrastructure.
Environmental Concerns
While flex fuel is often touted as a more environmentally friendly alternative to traditional gasoline, the environmental benefits are not as clear-cut. The production of ethanol can have a significant impact on land use, water consumption, and greenhouse gas emissions, depending on the source and production methods. This has led to ongoing debates about the true environmental impact of flex fuel.p>
Conclusion
In summary, while flex fuel vehicles offer some potential benefits, such as increased fuel diversity and reduced reliance on traditional gasoline, there are also several downsides that consumers should consider. These include reduced fuel efficiency, potential engine damage, limited availability, and environmental concerns. Ultimately, the decision to use flex fuel should be based on a careful evaluation of the individual's driving needs, vehicle compatibility, and personal priorities.
How much horsepower does E85 add?
However, it's not uncommon for engines to see power gains of 5% to 15% when running E85. This means that an engine producing 400 horsepower on gasoline could potentially see an increase of up to 60 horsepower on E85.
Will flex-fuel damage my engine?
The short answer is no. E85 has been tested and certified by the Environmental Protection Agency (EPA) for use in FFVs, which means that it is approved for safe use in these vehicles. In fact, many experts believe that using E85 can actually provide better performance than regular gasoline in certain models of FFVs.
Does flex-fuel get worse gas mileage?
While E85 is typically cheaper per gallon than gasoline it might be more expensive per mile. Since ethanol contains less energy per volume than gasoline, FFVs will generally get 15%-27% fewer miles per gallon when fueled with E85, depending on the car and the driver's driving habits.
Is it bad to use regular gas in a flex-fuel vehicle?
No, you can use regular unleaded gas in your flex fuel vehicle. It will not harm the motor. You should get better mileage than when using E85, which is up to 85% ethanol.
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.
Can you switch between flex-fuel and regular?
You can but you shouldn't. Your vehicle computer “learns” the fuel you are using and adjusts accordingly. You won't get your best mileage with your first tank of e85 nor with your first tank going back to e10 (which is by far the most likely fuel you are able to buy unless you burn some form of premium fuel.).
Why does flex-fuel burn so fast?
The loss in MPG is dependent on the actual ethanol content of the fuel that you're running. The drop in fuel economy is because ethanol has lower energy content per gallon than gasoline. E85 also burns faster than regular gasoline because it vaporizes faster.

What are common problems with flex fuel vehicles?
The drawbacks to using E85 include reduced fuel efficiency. The EPA states that flex-fuel vehicles return mileage that is between 15 and 27 percent worse than a regular gas-fueled engine because of the lower energy content in the fuel. This is offset somewhat by the typically cheaper price at the pump for E85.
Is it safe to use flex fuel all the time?
E85 is such an effective cleaner that some people run about 1 or 2 tanks worth of E85 through their engines instead of using a fuel injector cleaner. A surefire way to ensure that your engine remains clean is to use E85 often (or all the time).
