What's your 2023 Tundra's Real World Fuel Mileage

I have 8000 miles on my 2023. I recorded the mileage every 1000 miles. The first 2000 was 19.9 mpg.
Since then the next 6000 was 20.6 mpg. so an average of about 20.2

 

I just got a ‘24 Platinum with the 6.5 bed. Had it since mid Sep and have put about 1200 miles on it so far. It’s the 6v only, no hybrid. I reset the mileage gauge every time fill up and am getting about 15mpg. I’m always in “normal” mode and have not messed with either eco or sport mode.

Does this seem low? I’m seeing so many post with people get way better mileage.

 

Now that I have a few thousand miles on my truck, the average, for my use, is settling around 17-17.5 mpg overall, with extremes of 14 and 20.

Interestingly, I can report that it burns about 0.3 gph at idle, 1.5 gph at 40 mph, 2.5 gph at 60 and 5.5 gph at 80, give or take. Drag of course rises as a square function of speed, and a large brick is a large brick, aerodynamically speaking.

 

Give it another couple thousand miles and it should improve. These trucks apparently do "break-in" and many (myself included) have reported a marked improvement typically between 3-5K miles.
Mine was right where you are now at the same mileage until I hit roughly 3K miles and it took a turn for the better.
