The Ford Flex, with its distinctive styling and spacious design, offered a consistent 18.6-gallon gas tank size throughout its production years from 2009 to 2020.
The Ford Flex featured a gas tank size of 18.6 gallons through its entire run. This consistency meant drivers could always expect a uniform miles per gallon, which averaged 18 mpg for city driving and 25 mpg on the highway.
Despite its practical features, the Flex had a relatively short-lived run in the automotive market, making understanding its fuel capacity and efficiency nuances even more valuable for owners and enthusiasts.

Fuel Efficiency and Range
Each model of the Ford Flex, with its 18.6 gallon tank, offers slightly different fuel efficiencies:
EcoBoost
These are equipped with a turbocharged engine designed for higher performance.
While this results in increased power and responsiveness, it also leads to a slightly lower fuel economy compared to their non-EcoBoost counterparts.
Owners of the EcoBoost Flex can expect a more robust driving experience but should also plan for more frequent refueling.
Non-EcoBoost
These models are fitted with a standard engine, prioritizing efficiency over high performance. As a result, they generally boast better miles per gallon (mpg), offering a longer driving range per tank.
This makes non-EcoBoost models a more economical choice for drivers who prioritize fuel efficiency and longer intervals between fill-ups.
Impact on Driving and Planning
The consistent tank size across all Ford Flex models simplifies planning for drivers. However, variations in fuel efficiency, especially between EcoBoost and non-EcoBoost models, can impact budgeting for fuel. Regular maintenance of the fuel system is crucial for maximizing efficiency and longevity.
Gas Cap Release
The Ford Flex features a user-friendly gas cap release system, designed for convenience and security.
- Location and Operation: The gas cap release is typically located within the driver’s reach, often on the floor near the driver’s seat or on the door panel.
- Capless Fuel Filler System: Some Ford Flex models are equipped with a capless fuel filler system. This innovative feature eliminates the need for a traditional screw-on gas cap, reducing the likelihood of check engine lights caused by a loose or missing cap.
- Safety and Security Features: When the vehicle is locked, the fuel door also remains secured, preventing unauthorized access to the fuel tank. Additionally, the capless system includes a misfuel inhibitor, which helps prevent the wrong type of fuel nozzle from being inserted.
