★ Top Answer
The Ford Flex falls into the category of flexible-fuel vehicles, with E85 being the recommended flex fuel. You can also use regular unleaded gasoline in a Ford Flex. One benefit of owning a Flex vehicle is the freedom to use a combination of gasoline or ethanol without any issues. While E85 is suggested for optimal performance, you can also use 87 or 91 octane regular unleaded gasoline if E85 is not available. For enhanced performance, you can even mix gas with ethanol and methanol. The fuel tank capacity for a Ford Flex typically ranges between 18 to 19 US gallons, with the 2019 model having a capacity of 18.6 US gallons.
