I’m averaging 15.0 mpg under normal driving conditions in SC. Don’t tow/haul anything but groceries! 58,000 miles, K&N replacement filter is the only upgrade. What gives?

You bought a truck. That is pretty normal.

But here are some things that can help

First get rid of the K&N filter, unless you oil them perfectly each and every time they let a lot of dirt and stuff in. The paper motorcraft or wix filters are cheap and do a better job. They just get clogged so you have to replace them instead of cleaning them.

Second you can try cleaning the 3 MAF sensors and throttle body and doing a KAM reset.

100K on mine and I average 16 lifetime with a lot of towing and highway miles. I'm good with it, especially with the flawless performance so far.

Pretty much what you get. I get about 15-17 highway. 13 city.

15 to 17 on average except when towing camper then 8 to 9.

OP - what gear ratio do you have?

gaskinsjm

. New to the truck game and no much of a gear head. Is there somewhere on the truck I can locate this? Thank you.

That makes a huge difference. Look up your vin number online, or look on the sticker in the door jam.

Here are a few more things that add in
Tires - size, ply, weight, pressure
Rims - Size, weight
Lift
items in truck
elevation
driving habits
fuel
spark plug age

I figure I might be paying the price a bit in mpg loss for carrying the extra weight of the front drive train, but am not too disappointed. I've also added a bed cover and a heavy rubber bed mat to protect my mountain bike which both added even more weight.

I mix up a lot of highway and city driving and average around 16.9 to 17.1 or so on any given week. On long interstate trips, I have gotten close to 18 depending whether I am going up or down in elevation. Always better heading to the beach than it is returning for this reason.

I also run a K&N drop in filter and after running one for 14 years in my old 2001 Lariat, I have never had a problem with them. Proper cleaning and oiling is key. I did notice a slight uptick in mpg this past six months after putting new plugs in. 56K on mine.
