3.31 4x4 Max with about 3,250 miles
I get a combined 15.3. I get around 20 on the freeway and about 14 in the city. Obviously I do more city driving than freeway. But either way I'm nowhere CLOSE to the EPA's suggested numbers. And I can't imagine "breaking it in" further will help enough to get me there.
But as I've said before, at no point in my purchasing decision did I think I was going to save money on gas. I had hoped to get a combined 17 as that would cancel out the added cost of premium over my previous truck which was a 2012 V8 4x4 F150 with a 3.73 rear end.
