Can I put regular gas in a flex-fuel car?
As the owner of Kevin's Autos, I often encounter questions about fuel types and their compatibility with various vehicles. One common inquiry is whether it's acceptable to use regular gasoline in a flex-fuel car. In this article, we'll explore the capabilities of flex-fuel vehicles and provide clarity on this important topic.
Understanding Flex-Fuel Vehicles
Flex-fuel vehicles (FFVs) are designed to run on more than one type of fuel. Typically, they can operate on a blend of gasoline and ethanol, with the most common blend being E85, which contains up to 85% ethanol. However, these vehicles are also capable of running on regular gasoline without any issues.
Can You Use Regular Gasoline?
Yes, you can put regular gasoline in a flex-fuel car. Here are some key points to consider:
- Compatibility: Flex-fuel vehicles are engineered to handle both E85 and regular gasoline. This means that if you fill up with regular gas, your vehicle will still operate efficiently.
- Performance: While using E85 can provide certain benefits, such as higher octane levels, using regular gasoline will not harm your engine or performance. However, you may notice a slight decrease in fuel efficiency when using regular gas compared to E85.
- Fuel Availability: In some areas, E85 may not be readily available. In such cases, using regular gasoline is a practical alternative that ensures you can keep your vehicle running without interruption.
Benefits of Using E85
While regular gasoline is a viable option, there are benefits to using E85 in your flex-fuel vehicle:
- Environmental Impact: E85 produces fewer greenhouse gas emissions compared to regular gasoline, making it a more environmentally friendly choice.
- Higher Octane Rating: E85 typically has a higher octane rating, which can enhance engine performance and efficiency.
- Support for Renewable Energy: Using ethanol supports the agricultural sector and promotes the use of renewable energy sources.
Conclusion
In summary, you can confidently use regular gasoline in your flex-fuel car without any adverse effects. However, if you have access to E85 and are looking to maximize performance and reduce environmental impact, consider using it when possible.

Frequently Asked Questions
Are flex-fuel vehicles better on gas?
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.
Can flex fuel cars use unleaded?
The benefit of a modern flex-fuel vehicle, though, is that you can use any combination of gasoline and ethanol, whether it's 100 percent unleaded gas or 85 percent ethanol. Your vehicle's sensors will detect the blend and make the necessary changes.
What happens if I put 87 instead of 85?
Engine computers can usually adjust their timing to account for the increased octane levels, so if you put premium gas in a regular car, you probably won't notice anything. However, some engines are not designed to burn higher-octane fuel, and you may see a reduction in performance and fuel economy.
What happens if you put regular gas in a flex-fuel car?
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.
What to do if you put flex fuel in a regular car?
Once you've recognized the mistake, stop your car immediately to avoid additional damage. Then, it's a good idea to call for a tow and to get your system flushed by a trusted auto technician. In both cases, your fuel tank will need to be drained, and your fuel lines will require a thorough cleaning.
What happens if you accidentally put 87 instead of 91 in a Lexus?
Use of unleaded gasoline with an octane rating lower than what is listed for your model year vehicle could potentially result in engine knocking. If the octane rating used is less than required, damage to the engine may occur and which could void the vehicle warranty.
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.
Can you switch back and forth between 87 and 89 gas?
Your car will be fine, but you may notice a decrease in performance. It's best to fill up with the same type of gas that you're already using. If you use a lower-than-recommended octane, fuel can combust too quickly for your engine to take full advantage of it.
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.
Can you go back and forth between flex-fuel and regular gas?
Flex-Fuel Vehicles: If your vehicle is a flex-fuel vehicle (FFV), it is specifically designed to run on E85, regular gasoline, or any blend of the two. You can switch between them without any issues.
