How many gallons does the Ford Flex hold?
The Ford Flex holds about 18 gallons of gasoline, roughly 68 liters, in its fuel tank.
Capacity and Uniformity Across Model Years
Ford's official specifications for the Flex consistently list the fuel tank capacity at 18.0 gallons across most model years and configurations, including both front-wheel-drive and all-wheel-drive versions.
These numbers matter for planning trips and estimating range, even as real-world figures depend on many factors.
Here are the core facts owners should know about the Flex's fuel capacity:
- Fuel tank capacity: 18.0 gallons (68 liters).
- Real-world range depends on engine choice, drivetrain, driving conditions, and payload.
- Fuel gauge behavior and low-fuel warnings help you plan refueling before trips run short.
In practice, use the gauge and trip computer to plan refueling, especially on long highway journeys or in areas with limited service stations.
Estimating Range on a Full Tank
To estimate how far you can travel on a full tank, multiply the vehicle's miles-per-gallon (mpg) by the 18-gallon capacity. Actual range varies with driving conditions and configuration.
- Engine and drivetrain options influence mpg and thus range.
- Terrain, cargo weight, and driving style significantly affect fuel use.
- For planning, use your vehicle's current mpg readouts and a conservative estimate to avoid running low.
These considerations help you translate the 18-gallon tank into a realistic travel range for your Ford Flex.
Notes for Shoppers and Owners
What to verify when buying or maintaining
If you're shopping for a used Flex, verify the tank capacity in the owner's manual or the dealer's documentation, since this is a standard spec but can appear differently on some listings. In most years, the 18-gallon capacity remains a constant reference point.
Summary
The Ford Flex generally holds 18.0 gallons of gasoline, and this capacity provides a practical range that homeowners and road-trippers can plan around. While the exact range depends on mpg, driving conditions, and configuration, the 18-gallon tank remains a consistent specification across most model years.
