    Someone needs to run their truck out of fuel and see how much it takes to fill the tank so we can put this to bed.

    I just drove from Houston to Harrisburg, PA … only had to fill twice. Low fuel light came on at about 560 miles just past Meridian, MS and took a little over 32G. I forget where the second fill was, it’s all a blur. Very happy to average 17.5mpg traveling 70-75mph.

    Can hit 20mpg from Houston to hill country with a tail wind, but more realistically 18.5.

    It is nice with city driving that I only have to fill up once a month. My commute to work is 6.2 miles and get 12-14 depending if I want miles or smiles per gallon.

    Sorry for the late reply, been kind of MIA around here.
    Costco gas has the same requirement as the warehouse. You need to use Visa unless it’s a debit card then Mastercard is ok. I’m not sure about Amex but I don’t think they accept them.

    I want to know what I’m doing to not get this kind of fuel economy on highway travel. Max I’ve ever gotten is just under 17, long range drive, cruise, all highway.

    Do you have hills in your area? If so, it's probably the cruise control.

    Total elevation changes under 200. Almost pancake flat.

    That was only over a 46 mile distance, so my guess is it was pretty flat ground, mild temperatures, and just cruising 55-60 with very few stops, if any. I average 15.5-17 driving 4 hrs across hills 65-75mph going up to camp.

    Just got back from camp perry Ohio where my daughter participated in the CMP air rifle championships. From Maryland to Ohio and back I averaged 17.2 mpg which I thought was pretty darn good. The fillups were still shocking to my wallet but the truck was very comfortable throughout the trip.

    We just took our Tundra on a 600 mile round trip road trip. Most of the time I was driving at about 75 mph. Total mileage ended up at 16.0 mpg. That included a mountain pass and several substantial inclines, but also some good downhills and flat lands. I was plenty happy with 16 because the truck was so dang comfortable. All four of us had plenty of room, the truck was smooth and powerful, and we arrived at our destination feeling good. It's like paying extra for first class. :D

    I just did a 5200 mile trip for the second half of July. Averaged 14.5mpg (calculated off fuel used and actual distance traveled) fully loaded with tools, gear, rack, tent, etc. 3/2 lift on 35s. Mostly highway but mixed in offroad, exploring , and some in town use as well. Usually showed empty and took 30gal to tip off.

    Oddly my gas light never turns on until maybe 7 calculated miles left on the tank.

    Someone suggested running a 38 gallon Tundra out of fuel to confirm the capacity. I did just that within the first month of ownership. I made the calculation that the tank was clean enough to make the risk manageable. When the range counter reached zero, I zeroed out my trip A odometer and kept driving (City driving) until the truck died. Of course, I had a 5 gallon gas can in the bed. What I found is that I drove 93 city miles past zero range. I then added the 5 gallon gas jug and drove to a gas station where I filled with 32 gallons of gas.

    Yes. It's in the textbooks at every auto mechanic school.

    Any SAE or factory certified mechanic will confirm this.

    Tire size? Lift? No reason your Tundra shouldn't be close to 19mpg or better all the time in your conditions. Mine would...
