Guys our op hadn't stated whether 2 or 4 wheel drive. If 4 wheel drive, I doubt it, best is usually 12 city, 16 highway. 2 wheel will bump about 2 mpg avg. So 13 on a normal running no codes no rich motor. If he's got the smaller 4.6 two wheel drive and drives like your 80 year old granny, yeah he might be able to squeak out 17-18mpg. But he's not having any fun doing it.

Both. Even in Awd, the drag from the front components robs fuel efficiency. The extra weight of the differential, the axles, all the extra parts, fluid weight, etc .Same goes for accessories like AC. Ac compressors have a lot of drag. Type of tires can make a difference, along with tire pressure, even wheel alignment thats off, can Rob mileage. If the toe setting or camber is out of spec, the front tires struggle to roll down the highway. It's like our legs and feet, trying to walk down the street with a twisted worn shoe, or a knee, or ankle that's not in alignment with your hip and back. We get there, but it's a struggle. Same thing for your Suv. If fuel trim is too rich, like a vacuum leak, or misreading 02 sensor, and the computer compensates for it, fuel mileage drops accordingly.

I've been wondering about my poor suspension, I looked at my car in a resturaunt window once and it looked like my back wheels had gotten touched by the camber gremlin! Like, it's hard to describe, but in the reflection it looked like the front wheels were vertical, like | | and then the back wheels... / \
