I find that extremely hard to believe. I have a 2007 double cab with a 5.7 l engine and it has never even once exceeded 15 mpg regardless of what kind of driving (highway or city) and how hard I have driven it. How exactly did you calculate your mpg?

Just bought a 08 tundra crew with 4.6 the 4 tanks I have ran have been 18.2 high 15.8 low the thing has 16k on it [it was a lease rig] am thinking of puting in a K&N filter and going to mobile 1 but I don't look for any better but I can always hope. I keep track of all the gas I put in so will report back after I have put more miles on it.

#47 of 65 First tow on a green engine by webgood

Our new '08 DC, just 1,200 miles on the odometer when we started-out from Iowa for a round trip of northern Wisconsin with a 4,200 lb.-loaded hybrid travel trailer, 2 adults and 200 lbs. of gear. After 1,250 miles over 8 days we averaged 12.51 MPG highway mileage on 2/3's interstate and 1/3 good 2-lane with the usual slow-downs for small towns. Pegged the cruise at 57-58, left it in automatic and did not use 'tow-haul mode'. This is actual mileage based on starting with a full tank when leaving town and filling-up as we rolled back in, not 'calculated' by the vehicle computer.
I'm happy.

On a roadtrip that was 98% interstate running 77-78 MPH for 99+ % of that, the rest 55 MPH secondary highway driving on our '08 4X4 DC with a total of 500 lbs. of passengers and light cargo, got 17.92 MPG based on actual gas usage, not by the computer.

5.7, 4x4, SR5 with 18 inch wheels.
 
I broke her in with my first 800 mile road trip with 500 miles on the clock back in march. Got 18.7 all highway, going no faster than 65-70 mph, with no heavy throttle application. Incredible when I consider my 04 Dakota Quad Cab with 4x4 and 4.7 almost never beat that number and the truck was 1000 pounds lighter, 3.55 rear end as opposed to the Tundra with over 100 fewer horsepower.
 
Of course I haven't driven it like that or seen that mileage since. The other day some idiot stopped in front of me on the merging lane with 65 mph traffic flying by. I just floored it when I saw a small gap and the next car flying towards the on ramp never even got close to my rear end. Can't drive a truck that's capable of that for ultimate mileage, no matter how hard I try.

I own a 2008 Tundra 4x4 Double Cab SR5 4x4, currently has 27k on the clock. Summer driving my Tundra avg.s around 19.4 mpg, winter it drops down to 16.9 to 17.3 according to the handy little computer on the dash. I also use my Tundra to plow with. When I am plowing snow it avg.s 13.5 which isn't bad considering the 7 1/2' blade on the nose and the Blizzak snows on the truck. I use 87 octane fuel and "treat" the Tundra to 92 octane once in a while.
The sweet spot for fuel economy seems to be not going over 70 pmh on the interstate and keeping the truck at an avg. speed of 40-50 mph on numbered routes that allow such speeds. If I get stuck in traffic all bets are off and fuel economy suffers as you would expect. I also tow with my Tundra quite often getting up to the 10,300 lb. max. rating. My fuel economy when towing around 10k lbs. avg.s 13.1 to 14.4 mpg. Which I think is reasonable given the amount of weight being towed.

Being retired I've seen lot's of changes in auto and trucks ! Some are good,some are not ! Owned 5 new trucks & 5 new cars pluse used ! Never used syn. oil or k&n air filters,never had to rebuilt motors or trans.! Had a new 68 toyota corona, a new 78 ford f100 with a 6cy 300 motor,it got 19mpg ! Pulled a travel trailer all over the mountains with it (three speed on colum) (had 140,000 mi.when sold)! Had a 98 tacoma 4x4 ext. cab. 4cy. pulled 3000 lbs. boat with it ! Had 194,000mi. when i traded in (did'nt burn a drop of oil)! Have a 09 frontier crew cab 4x4 that gets 22.5mpg going 65mph in 70%-30% driving! 21 going 70mph on Int.(20 at 78mph)! Blessed ! pulled a 27' travel trailer for over 8hrs. in upper 90's! Looking real hard at 2011 tundra,but 1st review 17mpg with 2wd ! "Come On" Myths: your auto will get better gas mpg after break-in,syn. oil will give you more mpg !

#54 of 65 2001, 4.7 190,000 miles Happy with MPG by ezydriver

I use a fully calibrated "ScanGuage." At 55 mph the Tundra gets 23.0 MPG and at 65 mph it gets 20.0. I get a lower MPG when there is alcohol in the fuel , 10 to 15% lower. The best MPG seems to be when name brand fuel is used with Shell gas the best. Hills have no effect as long as I start and finish at the same elevation, ( I have an electronic altimeter). I drive very gently - for example The front brake pads have been changed once and now at 190,000 miles i will replace the rear drum brakes soon. Timing belt was changed at 160,000 miles.
(K&N air filter and Full synthetic oil and transmission fluids from day 4)
