Interesting thing with the 2013 ranger I have - currently running 8.5L/100Km reported on the display, and it's reasonably close to what I work out on the receipts. That's .4 higher than factory and it's on aftermarket suspension with about a 2" up at the back and 1 and a bit at the front.
Ford replaced the rear springs without touching the front which resulted in a 3" lift at the back and 1" drop at the front - made the thing a widowmaker fu*ken dangerous. I stopped driving it until I fixed it it was that bad, totally fluffed the front end alignment and it was completely uncontrollable. But, interesting finding with that much of a wedge driving down the road - fuel consumption dropped by about 1.4L/100Km, I was getting 6.9L/100Km. So possibly the aerodynamic effects of how we set the ute up on aftermarket suspension has more of an effect that we would think. The snorkel does more for drag and increasong fuel consumption than anything else I suspect, especially the ones without a scoop on them and face the rear...
