Relative to last truck w/5.4-uses a lot less throttle accelerating or going uphill. Didn't track mpg as odometer is off after replacing 18" wheels w/20" wheels, which rendered fuel economy gauge inaccurate. Used gps calculated mileage a few times when not towing,was in 18 mpg range(combined city and hwy). Probably could get better mileage if I could keep foot out of ecu.
Physics dictates the use of more energy to move more mass, so any engine would use more fuel, the technology in this motor (direct injection,turbocharging etc) does a more efficient job.
