2014 Tundra SR5 gas capacity

Hey yall.
Thanks for the acceptance to the forum.
I just bought about 1 month ago a 2014 Tundra SR5 4X4.
I've filled it up 3 times now from the gas warning light being on.
I'm only able to put in 20.7 is gallons each time.
I've read it should be 26.
Seems like a lot of reserve if that's the case.
Only getting about 200 miles a tank.
Any help on this is appreciated.

 

That’s to be expected. My gas light comes on and I have fillups between 28.5-30 gallons on my 38 gallon tank depending on how level the truck is from suspension sag.

 

Welcome from NY.

That's normal.

 

Agreed, thats just how these trucks are for some reason. They definitely have a fair amount of reserve after the light comes on.

 

Welcome to the forum..
As others stated it's normal.
I have the same truck you do.
The most I ever put in the tank is 21.5 gallons in the last 9 years.

You should be getting more than 200 miles a tank.
I get about 315 a tank @ 13.2 MPG according to the dash display.
I'm pretty heavy on the gas pedal..



If you push the DISP button down and hold a few seconds it will reset the dash stuff.
But it will take a few tankfuls of gas to be accurate again.

 

Thanks everyone.
I was about to put a camera down the filler tube and make sure there wasn't something in there.

 

It's reserve gas that cools the fuel pump.
