these vehicles are not great for MPG compared to other trucks. the V6 is under powered . if it had more torque the MPG would be higher esp in areas of mountains/hills. then the design is like a block , no smooth air flow when this comes down the road ,so the higher the speed the MPG drops.Right, the better tires are worth more to me than mpg. But, like stated above, I'd like to find figure out the reason it is that low.
my 2016 @45-55MPH small hills not flat ground I get 19.6 MPH. @60 MPH 18.7MPG then @70 MPH 18.2 MPG. @ 80 MPH 17.9 MPG...
also type of gas used NO MPG change 87-93 octane.
on elevation use I do no see that this would have much if any effect on MPG .. if operated on high elevations and no big grades to climb should not be any difference since these do not have carbs in them. the PCM has sensors to properly adjust for elevation . the air fuel ratios are locked in very tightly .
the higher the elevation will cause a loss of power though. and this vehicle at sea level is not all that much of a power house ride. so if you are up high elevation and climb steep grades then this may be why its 13 MPG...
this vehicle needs 50 more HP...
