What Our Members Are Saying about the Real Gas Mileage of the Ford Expedition

Ford Expedition Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2008	4dr SUV 300-horsepower 5.4L V8 6-speed automatic 4WD w/low range	Amazing fuel ecomomy for size....17.5 mpg overall, have hit over 20 mpg on 5 tanks, high is 22 mpg. 6-speed auto had 2 overdrives. see full Ford Expedition review

Ford Expedition Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2014	0	Seriously, what a pig. Not towing - mostly highway (over 400 miles worth) but some city driving as well - in 600 miles, we averaged 13.9 MPG. The car's computer appears reasonably accurate (as a rental, I do not know if it was really full when picked up but the second tank MPG was within 0.5 MPG of my calculation based on mileage). Yes, there were generally 6 passengers (4 adults, 2 kids) and the AC blowing (front and rear) to combate the Texas heat, but I was light with the thottle and it was quite flat. I am well aware no one will buy one of these based on gas mileage but this performance is just abysmal. Hopefully the next generation will improve. see full Ford Expedition review
2007	4dr SUV 300-horsepower 5.4L V8 6-speed automatic 4WD w/low range	It weights 3 tons, so fuel economy is not going to be great, but 13-14mpg in town and near 20mpg on the high way is achievable. see full Ford Expedition review
2005	4dr SUV 300-horsepower 5.4L V8 4-speed automatic RWD	13 in the city, 18 on the road, not bad but a diesel would be better see full Ford Expedition review
2004	4dr SUV 260-horsepower 5.4L V8 4-speed automatic 4WD w/low range	Vehicle is expensive to operate see full Ford Expedition review
2003	4dr SUV 232-horsepower 4.6L V8 4-speed automatic 4WD w/low range	10.7 mpg. Need to say more? see full Ford Expedition review
2000	4dr SUV 260-horsepower 5.4L V8 4-speed automatic RWD	The 5.4 L engine gulps fuel. Usually get 14 around town and best of 18 mph on highway if easy on the throttle. Probably all that can be expected of such a heavy vehicle with high wind resistance. see full Ford Expedition review

Cadillac STS Real Gas Mileage: Cons

2006	4dr Sedan 320-horsepower 4.6L V8 5-speed shiftable automatic RWD	16 city/21 highway. Buy it only if you can afford it with out complaining. see full Cadillac STS review
2005	4dr Sedan 320-horsepower 4.6L V8 5-speed shiftable automatic AWD	This car is thirsty. I live in flat country and I get 15 mpg with 80% highway traffic. I only get 19 mpg on trips. It probably needs a 6th speed overdive for the highway. see full Cadillac STS review
