The fuel capacity of a Ford Explorer varies depending on the model year and engine. It typically ranges from 18 to 21 gallons. To know the exact fuel capacity for your specific Ford Explorer, you should check:
* Your owner's manual: This is the most reliable source.
* The fuel filler door: The capacity is often printed on a sticker there.
Without knowing the year and trim level of your Explorer, I cannot give you a more precise answer.
