Should had give some mpg when not towing with the 5.0L F150 Crew 4WD 5.5' bed. I have a mix of expressway and town driving. The 5.0L gets between 17.5 and 18.0 mpg. I have an alternate route which consists of a lot of turns and stops on highways, back roads, and town roads. I get about 16.5 - 17 mph when I take my time and about 15.5 - 16 mpg when I hurry. This is all mixed driving.
When I don't change my speed up and down a lot, and drive consistently on the expressway @ 70 mph, I get about 21 mpg. With slowing down, speeding up, a lot of lane changes, and higher speeds, about 19.5 mpg.
City/town driving is between 15 and 16 mpg depending on stop and goes.
This is the best mileage I have ever got out of all of my midsize (V6 and V8)/fullsize SUV and trucks. Wife's 2.5L 4WD Escape gets about 29 mpg on expressway but it's a subcompact with a 4 cylinder engine.
