You'll find the best information by:
* Checking the EPA's FuelEconomy.gov website: This is the most reliable source. Enter the specific year and model of the Expedition to get the official EPA estimates for city and highway mileage.
* Consulting the owner's manual: If you own a Ford Expedition, the owner's manual will list the expected fuel economy.
* Looking at online reviews: Websites like Kelley Blue Book (KBB) and Edmunds often include fuel economy information in their reviews, but remember these are user-reported and may vary.
Generally speaking, expect lower gas mileage than smaller vehicles. Older Expeditions will have significantly lower MPG than newer ones due to improvements in engine technology.
