What gas does a Ford Flex take?
The Ford Flex takes regular unleaded gasoline with an octane rating of 87, and it is not a flex-fuel vehicle in the usual sense. In short, you should fill it with standard gasoline.
The Flex was produced from 2009 to 2019 and is designed to run on ordinary gasoline. Always check the specific model year’s owner’s manual or the fuel-filler door label for the exact octane requirement, as specifications can vary by engine option and region. Using 87-octane gasoline is typical, while higher-octane fuels are not required unless you encounter engine knocking or guidance from the manual.
Fuel type and octane requirements
Most Ford Flex models specify regular unleaded gasoline with a minimum octane rating of 87. Premium fuels (91–93 octane) are not required for normal operation and are generally not necessary for the standard engines used in the Flex.
Flex-fuel capability and ethanol blends
Unless a specific unit is labeled as Flex Fuel, the Ford Flex is not typically considered a flex-fuel vehicle. If a particular version can use ethanol blends, the allowable fuels (for example, E10 or E85) will be indicated on the fuel-cap label or in the owner’s manual. In most cases, regular gasoline is the default recommendation.
Model-year specifics and guidance
Across the 2009–2019 production span, the recommended fuel for the Ford Flex has been regular gasoline with an octane rating of 87. There is no diesel option and no persistent requirement for premium fuel in standard configurations. For precise guidance, consult your owner’s manual or the fuel-label attached to your vehicle’s fuel filler door, as engines and regional specifications can vary.
Summary
In summary, a Ford Flex takes regular unleaded gasoline with an 87 octane rating. It is not typically a flex-fuel vehicle, but always verify the exact fuel requirements for your specific model year and engine configuration using the owner’s manual or the fuel-cap label.
Can you put regular gas in a flex car?
Can You Use Regular Gas in a Flex-Fuel Vehicle? One benefit of flex-fuel vehicles is that they are also compatible with regular gasoline. FFV engines have sensors that detect the gasoline-ethanol ratio in the fuel and make adjustments for optimal performance.
What kind of gas do you put in flex fuel?
A flex-fuel vehicle can use any blend of gasoline and ethanol, from regular unleaded (E0) to E85 (85% ethanol). You can mix these fuels in the tank, and the vehicle's sensor will automatically adjust to the blend being used.
Fuel types
- Unleaded gasoline: You can put regular unleaded gasoline with an octane rating of 87 or higher in the vehicle.
- E85: This is a gasoline-ethanol blend that can contain between 51% and 83% ethanol. E85 is often labeled as "flex fuel".
- Blends: You can mix gasoline and E85 in the same tank without any risk of damage. The vehicle's sensors will detect the blend and adjust the engine's performance accordingly.
What to know
- The vehicle's fuel system is designed to handle either fuel type.
- Using higher ethanol blends like E85 may result in lower fuel economy compared to gasoline.
- Always check your owner's manual for specific fuel recommendations and requirements.
- Some stations may also have other blends, such as E15 or E25, and many modern vehicles can use E15.
What kind of gas does the Ford Flex take?
Use only UNLEADED gasoline or UNLEADED gasoline blended with a maximum of 85% ethanol (E-85) in your Flex Fuel Vehicle (FFV).
What happens if you put 87 in a flex fuel car?
Yes, it is perfectly fine to use 87 octane gasoline in a flex fuel vehicle (FFV). Flex fuel vehicles are designed to run on any combination of gasoline and ethanol, up to a maximum of 85% ethanol (E-85), and the vehicle's sensors automatically adjust for the fuel mixture. You will not cause damage to the vehicle by using 87 octane gasoline, but you can expect the vehicle to perform normally without any issues.
- Automatic adjustments: FFVs are equipped with sensors that detect the ethanol content in the fuel and automatically adjust the engine's timing and fuel injection for optimal performance.
- Normal operation: Using 87 octane gasoline will result in normal vehicle operation. The vehicle does not require a higher octane fuel to function correctly unless the vehicle's manufacturer specifies a minimum requirement for gasoline-only use.
- No harm: Unlike using E-85 in a non-flex fuel vehicle which can cause damage, using regular gasoline in a flex fuel vehicle is safe and will not damage the engine or fuel system.
- Fuel type: You can use any octane level of standard gasoline (87, 89, or 91) in a flex fuel vehicle.
