Fuel Tank Capacity

So I have a 2012 DCSB TRD O/R and all the vehicle specs say that the truck has a 21 gallon tank. I have around 8,000 miles on it now and every time I fill up I have never gotten past 17.2 gallons. That was even with the light on and the needle on E. Seems like it is an 18 or 19 gallon tank. The most miles I got on a single tank was about 345 after putting 17 gallons in the tank. Are the specs wrong or WTF

 

your manual should tell you that when the light comes on you have like 3 gallons remaining.



want to really know how big the tank is? run that sucker out of gas

 

There is a couple gallons remaining when the light is on and needle on E

 

general acceptance has been that there is still 4 gallons in the tank the moment the light comes on. its a 21 gallon tank. i usually fill up before the light comes on and only ever fill up about 16-17 gallons

 

I almost thought I was gonna run out of gas once. Light came on and I was about 20 miles from the next gas station. I used to have an 06 Pre-runner and remember putting more than 17 gallons in that one.
Thanks for all the feedback on this. I wanted to make sure I wasn't going crazy

 

My light comes on and I always put 18 gallons in it.

 

i don't usually run mine empty, but one time i was in a hurry on the interstate, and I drove about 70 miles after gas light came on, only filled up like 19 something gallons

 

oooh just checked my fuelly, it was actually only 18.84 gallons

 

Call it reserve? Put a 6-gal can on board and drive it until the fuel pump starves?! :-o

 

Light comes on mine with 4 gallons in the tank, and when the needle is on the E line, I have 3 gallons (can put 18 gallons in) still... As I get about 16 mpg, that means I can go 48 miles before running dry from the E Line on the gauge.

 

Brave man

 

i'm confident we could all get roughly 80 after the light goes on, but i was surprised it filled less than 19. I never really wait that long, i pretty much fill up whenever i cross a decent priced BP station (BP credit card 5% off)

I always fill up at half a tank, never less than that. Also run a fuel system stabilizer to eliminate all the ethynol build up every other tank.

 

On my 012, the biggest fill for me was 20.18 gallons so I do believe it is a 21 gallon tank. However, the last 2 gallons of the fill have to go in VERY slowly. If you stop filling after the initial click of the nozzle you will not reach full capacity.

 

how long did you run it on the empty light to get that? i thought the first click was when it was full?

 

Going past the first shut off is a good way to mess up your charcoal canister, and they are not cheap.

I usually turn on A-TRAC and it gives me an extra 5 gallons of fuel.

 

Fuel pump is in the tank, must take up some room, never put more the 18 gal even, and I run till light comes on usually.
