2.7 mpg/performance

I have 24182 miles on my 2015 XLT FX4 SC with a 2.7 EB and lifetime hand calculated MPG is 16.77 (I'm in Kansas) I had 43446 miles on 2011 XLT SC with a 3.5 EB; lifetime MPG of 17.17. 18 in wheels/tires on both; the 2011 had a 3.31 axle, the 15 has a 3.55.
I drive the same route to work each day, use the same gas station etc.... nothing has changed... I LOVE my truck, but would have bought a 3.5 EB knowing what I know now.

increase your tire pressure, I run 42psi in mine, been doing it for 35k miles without issue (no uneven wear like people tell me I will have). I see a difference between that and 35psi.
I always have the "green fuel bar screen" up on my dash display and reset it frequently. It averages your mpg's since your last reset, since there are a ton of variables while I drive everyday, keeping it current allows me to see what the truck is actually getting. While watching the screen you can adjust your driving in real time to pick up some efficiency.
I try to accelerate at a rate that has the truck shifting around 2k rpms. It's not "grandpa" speed by any means, I am usually going at the rate of traffic.
If your commute consists of 45-50 mph roads, I have found that my truck will hold 5th gear up to 49 mph. It shifts at 50 mph and will hold 6th down to 45 mph before downshifting. Accelerating up to 50 to get into 6th saves me some rpm's over being at 45 in 5th.
The green screen is probably the most valuable tool out of all of them though. your truck will probably have a different "sweet spot" due to you having 4wd and different gearing than me but the concepts should be the same.

Went from a 2015 scab xl sport 2.7l to a 2016 screw 2.7l lariat... I can't even get 20 mpg on a flat going 55 MPH.. i used to be able to get 26 plus going 60-65..
No idea what's happening

Your gas mileage moves so much depending on driving habits and amount of full left. When I just reset yea it shows me with 30 MPG. But as I drive or punch it, it drops drastically. It's just not good info to be saying here's my MPG based off a short amount of data

I also know that if I'm running down the hwy on a flat section doing 55 sure at that point I'll get 25+ but that is rare and lasts for short periods. So if I wanted to take a picture of my dash getting that crazy high MPGs I could do it but it would be absolute BS.
I've been tempted a few times to go to the dealership and test drive a new one on a longer ride and see what it does. However if I did that and saw better results I'd be pissed then depressed.
Seeing the data from fuelly is more believable and at the same time very puzzling. Again, I pose the question how can 2 vehicles built exactly the same have such different results????

Think about this from the majority perspective. First off, these trucks were not designed to average over 22MPGs and so when we see people making these outlandish claims of that and beyond it comes off as BS.

My 29mpg tank is over 600 miles, I can reset my trip screen at the top of a bridge and coast for a few miles and show 99.9mpg's....
Take two identical trucks, put one in south Florida and one in Alaska, even with the same driver, there will be a mpg difference I promise. Just like everyone's elevation above sea level will have an effect (ever have to re-jet a carburetor to run a dirtbike or 4-wheeler in the mountains)? Add air temperature, hills, traffic, and every other variable and you will see differences. It doesn't mean one persons results are BS, it just means their results are different than yours.
I was at the dealership I bought my ruck at yesterday wanting to drive a 10 speed but unfortunately they haven't received any yet. I was curious to see if the 10 speed would do better than mine, in theory it should but as we all should know, individual results will vary.

I have always got best mpg in the south east of the country. Think the gas is just better there with the lower / closer to sea level. Of course stop and go traffic doesn't figure in with the above statement, only the long interstate drives qualify in my opinion. Now if I was to be driving in Clearwater I would be crying bad gas mileage. Lol

There are so many variables that determine each individual's mpg's. To me it's outlandish that someone is averaging 16mpg's in a similar truck to mine but I could do the same thing if I ran mine like I stole it.

I've even gone to the extreme of driving like a grandpa and to the other extreme of driving in Sport mode more aggressively. In both scenarios I did not see much if any improvement. Running in Sport mode all the time definitely chews up more gas which I expected.
All this said it's still much better than what my 02 5.4 ever got and I get more power to go with it so I'm pleased.
