i live in the mountains in Colorado at 8500 ft. My 2016 2.7 regular cab 4x4 has averaged 23 mpg since i bought it in Feb 2017. The speed limits very between 40-60 mph and i go back and forth to Colorado Springs and also Cripple Creek.(elevation close to 10k) I d drive with a light foot but am pleased with mpg here in the mountains. Highway travel at 70mph between Colorado and NW Missouri drops to between 20-21.

OP, still seems a tad low, even in the circumstances of low miles, winter, hills, etc... But, as mentioned, there are SO many variables to fuel efficiency.

I would experiment a bit, to see how it changes. Try a tank with more aggressive driving, sport mode, etc.., to see if it gets significantly worse. Then try a tank like you're driving on egg shells, see how that turns out. Try to get a range for extreme one way & the other, and also see how it goes when warmer weather arrives, and summer fuel comes back. Try different gas stations as well. After all this, see where you stand. Then you might get a feel for a potential problem with the truck, driving habits, conditions, etc...

How do headlights affect MPG ? Please do not tell me the alternator drags enough to be a factor.

Nothing is free, unless they are solar powered? Do they put out heat? That is how much energy they use. Why even shut off the headlights when you get home if they use insignificant power?

Id like to stay away from a tune for now if possible. I went through this whole process with my 2015 Subaru STi and it was super expensive, and voided the warranty that I had.

This is crazy to me lol, I have worked with cars just about all my life and have never heard of winter gas... I guess the more you know!

I just filled up the other day, Ill see if I can get that average up some to get my monies worth out of this 2.7

HUH ? I am only saying I do not believe using the headlights affect MPG. If you believe it, fine with me.

UncleG

I can't find anyone around with a 2.7 who likes it for towing or who thinks they are getting the MPG they expected.

You would be incorrect. It does affect MPG. Only slightly, but all electrical loads affect MPG negatively. Note in the attached reference, DRLs use less power than normal headlights. And keep in mind that even if the drop is only 1%, and therefore barely noticeable by an individual driver, multiply that over all vehicles on the road and it's a lot of fuel.

Once I learned about FORScan, I turned on my fog lights as DRLs for safety.

I see a difference of about 1 to 2 mpg loss in my 2.7 in the winter. If we have a lucky warm spell and it hits 60 plus, I notice my fuel economy improves. The freezing cold definitely makes it harder for our trucks to move along the highway efficiently. Going to Knoxville.....25.5 mpg there.......20.5 back. One way is downhill the other uphill, so obviously terrain plays a huge roll as well.

Tows my boat fine and I'm getting pretty good mpg considering my driving habits.
