2.7 mpg/performance

I see a wide range of performance and MPG statements in this thread. I'm not here to debate them, rather to get others constructive input on whether my truck is about average, or below average on MPG. I know no 2 situations are the same, but it appears to me that my truck is getting pretty poor highway mileage. I have a 2016 SCREW, 4x4, 2.7EB, 3.55 Gears, Stock tires (18" wheels), tire pressure at 40psi, XLT sport, 302A. Up to about 55-60 MPH seems to get reasonable mileage on the highway. Once above that, MPG seems to drop off considerable. I have just under 4000 miles now, 2300 in the last 3 weeks. Drove from Limon, Colorado (elevation of 5300 feet) to Amarillo, TX (elevation of 2600 feet) - distance of 340 miles at 65 MPG. There was about a 20 MPH side wind, but the average MPG for that leg was 15 MPG. As I'd drive through the small towns (slower speed) my AVG MPG would increase by 1 or 2 MPG until I exit town and resume the 65 MPG speed, which would then drop the MPG back to 15 MPG. I've been in South Texas for the past 2.5 weeks and drive about 80% highway. I've never seen highway MPG anywhere close to 20 MPG or above. I'm about 17-18 MPG at 70 MPG. That is about what I get in town! I'm not heavy footed or an aggressive driver and try to conserve fuel (that was the reason to buy the 2.7EB). No check engine lights, no Service (wrench) lights on. Does this seem about normal? Or does it seem like there is an issue going on with highway driving?
I see differences in weather, temperature, humidity, wind, ETC. It could be a case of me having very close to optimum conditions right here right now and you being in a worst case scenario driving in the conditions you were in. That is just a shot in the dark guess though. I wouldn't assume that there is something wrong with your truck because for all I know my truck might get the same thing as yours on the drive you took.

Take a run up to Chicago tomorrow and you will understand real world mileage per gallon. I got 21 today on 225 miles at 70 mph in 11 degree temps with a tail wind of 10 mph. In warmer weather it would have done 24 mpg. 3.93 e-locker, screw, 2.7L xlt 302a, with 14,500 miles since new and 23 mpg since new on cluster. It has dropped from 23.6 so far this winter. By spring I hope it isn't far below 20 mpg. My driving is mostly 70's so my truck carries a near 60 mph average since new. Almost impossible to get unless you interstate all the time. Most have a hard time getting much into the 30 mph average in all their driving.

Mine loves high temps. 90/100 degrees is where it is at its best power and miles per gallon. Will then average 24 mpg untill it cools back into the 70's. loves it hot an turbos go to work.

Hotter ambient temps equal better gas mileage. Cooler ambient temps equals more power, ESPECIALLY with turbos/forced induction. Excessive heat kills horsepower.

That was proved wrong when ford an chevy pulled against each other in Arizona. 2.7Lbeat Chevy untill it cooled down. Then Chevy just beat Ford. The 2.7L liter likes it hot with direct injection.

Sorry but I didn't see this post yesterday. I would think you should have seen sway better than 15 mpg's at 65 while dropping 2700 feet in elevation. Now to be fair, I am probably no higher than 20' above sea level here unless I'm on a bridge so I have no real world knowledge on what my truck would get at the elevations and conditions you were driving at.
I see differences in weather, temperature, humidity, wind, ETC. It could be a case of me having very close to optimum conditions right here right now and you being in a worst case scenario driving in the conditions you were in. That is just a shot in the dark guess though. I wouldn't assume that there is something wrong with your truck because for all I know my truck might get the same thing as yours on the drive you took.

When u first put in a 93 octane gas the trucks computer hunts for 100 miles to figure out its mileage. U notice a increase in torque also.
