    Ive got a 2016 Tundra DC with the towing package. According to my window sticker, and what ive read on here the 38 gal tank is part of the towing pkg. Yesterday my low fuel light came on pulling into the parking lot at work. I had planned on filling up before heading to the beach anyway no biggie. According to the display it said 15 miles to empty when I filled up and I was only able to get 30.7 gallons in. So when does the low fuel light come on and how can I tell for sure if I have the 38 gal tank??

    When the gauge reads empty, there's about 6 gallons left. It supposedly needs it to keep the pump cool.

    the 38 gallon tank is standard on the limited and platinum trims. it is also part of the sr5 upgrade package if you have the sr5 trim.

    for me, the low fuel light comes on when there are 8 gallons left in the tank. when I first got the truck, the distance to empty display was way off. now, it is closer to actual, but it is still less than what I have left in the tank. I consider any calculation on that display to be an estimate. I always calculate my MPG on every tank so I know how far I can travel. when the low fuel light comes on, I know I have about 128 miles left in the tank.

    if you put 30 gallons in the tank, you have the 38 gallon tank :)

    Thanks for the info guys. I had never ran it that low before so I was expecting a 36 gal or so fill up. When it only held 30 I was thinking maybe I had a smaller tank.

    I've gone thru the same thing every time I fill up. Math never adds up to 38 gallons in the tank. One time I stopped to fill up with 35 miles to go. With a guesstimate of running at 15 MPG, that would be approximately 2 gallons left in the tank. Expecting to pump in 36 gallons, I only pumped in 30ish. Also, with 38 gallons at 15 MPG, I would expect distance to empty to be closer to 570; I only get 500 at every fill up.

    So I just remember that I hate math, ignore it and move on with my life and just enjoy the truck. . . ;)

    I would love to have this problem of only getting 30 gallons on a fill up.

    Yeah, me too. I went dirtbiking 2 weeks ago in Northern Nevada. Stopped in Fernley, NV, to fill up and was following a friend to his secluded riding spot. He said the place we were going to was "a coupla" hours away. First we drove through Indian reservations, then got on gravel highways, then dirt roads, more gravel roads, then narrower dirt roads. About 3 hours later, we finally get there. I think we were like 20 miles from Oregon and I didn't see a single open gas station along the way. I look at my gas gauge and it's under 1/2 tank. Oh shit. So we ride our bikes and quads all day long and when we were done, we dump all the extra bike fuel we had left into my truck. Gauge is still reading slightly under 1/2 tank. Oh shit. We take off for Fernley and I'm stressing the whole way. About 30 minutes out of Fernley I get 0 miles to empty. Now I'm worried about running out of gas and burning out my fuel pump. We finally get there okay, but that was some unnecessary stress I just went through. Our little 26 gallon tanks are bullshit.

    Damn good thing you had fuel for the dirt bikes that was left over. On remote locations, or the unknown I usually carry extra fuel.

    I have a 28 gallon tank, when I fill from the fuel light being it takes about 30 gallons. First time this happened I thought the gas station pump was wrong, but it's happened a few other times as well. I think you have a 28 gallon tank which probably doesn't completely account for all the space in the tank and filler neck


    Edit**** I'm dumb, SR5 upgrade package adds the 38 Gallon Tank. The window sticker doesn't indicate this, so if you go by that, it gives the impression that it came with the 28 Gallon that usually comes with the SR5.

    the 2016 tundras come with either a 26 or 38 gallon tank. not sure where you are getting the 28 gallon size from.

    Just a few, more to come
    My fuel light would come on at about 20 gallons with the 26 gallon tank, zero miles to empty on the display and there'd still be a good 4 gallons left.
    Towing and getting 8-10mpg and going across rural nevada was not my favorite thing. After upgrading to the 46 gallon transferflow oversize tank and couldnt be happier! really nice being able to go 400 miles while towing and not having to stress where the next gas station is, and going 2 weeks of my normal driving around town between fill ups is nice too.

    May wanna fact check but I think the front bench seat eliminates the larger tank option....not sure why but I've heard those alligations

    Yeah I have a Limited with the towing package, I still have the window sticker which states 38 gal tank. According to my display it said 15 miles to empty and I was only able to get 30 gals in it which made me think I had a smaller tank.
