Today made a 3 hour trip from Sacramento down to Fresno and got 23.4 mpg highway. 2019 Tundra SR5, 5.17 engine, no bed cover, 2wd. Just kept it about 65 mph not using cruise control. Tires are Les Schwab Back Country All Terrains 275 70r18s.
I have 2012 5.7L 4WD Crewmax with factory setting for air pressure, clean air filter and mass flow sensor, new plugs, run 87 octane. I don't race around. I get 13.1 MPG. I don't understand the variation on all these reports.
It all depends on how you drive, intake or not. I’ve had two tundras, a 2012 and 2018. I have made it as high as 20.5mpg with no modifications. If you take it easy on the accelerator your mileage increases. If you drive with the pedal to the floor and are doing 75, don’t expect good mileage. My average when I am not towing is about 18mpg.
Trd supercharged 37 inch tires.She probably gets 18.5 mpg towing my 4,000 lbs+ boat to the lake. But i have to use 91 octane. If it was 89 you could say itd be like 17 mpg money wise. I honestly dont know else how to test it cuz thats all i use her for. The supercharger added incredible torque and speed. I towed 10,000 pounds up over 11,000 ft like it wasnt there before i put the big tires on. Im not sure how it would be now though. Same 4.30 gearing
Its because of the cover on BED. I did it to and got 23.2 on a trip to S,C, on a 2014 Tundra 5.7 engine. Don't trust the truck mpg. Use a Cal and get the correct mpg. But it is becarse of the Tonneu comerl. I changed to a topper and got 20. 5 or something like that. Did it twice . I now have a 2018 and get 19 by truck gage.
Ian Brasseur like I give a shit about a trade in. I run mid 13’s at over 100mph with simple bolt ons a mile above sea level, get better mileage weighs less, tow more, coil spring rear suspension rides and off roads better, and also better aftermarket. The ram is absolutely better at everything except resale but I’m not selling mine because I’m enjoying it too much. Enjoy your slow, thirsty, cheap interior and resale value in your tundra the worst rated truck in every test.
Wildcat Cowboy the 5.9 Cummins and 7.3 powerstroke are super reliable too. Doesn’t mean they can compete with 6.7’s and the 6.6 modern diesel stock vs stock.
Shell gas is the reason for good milage on a Tundra. I made a trip to S. C. and got 23 mpg, I though it was all the time but once back to Fl , I got usually 20. Big difference in gas. I used Citgo in Fl . 87 oct on both gases.
Ok, whatever-2 wheel drive??, I run premium fuel always with all oils being synthetic-motor and axles. I have 35 inch mudders with a lift and big push bar. I get 11.2 average, I do drive 80 m.p.h. down interstate with the AC cranked. You must be a much better driver than I am.-Still LOVE the truck, I didn't buy it to get 20+ mpg, I drive my Honda Crosstour when I'm trying to get good mileage.
Just got a new 2017 model. First interstate trip I locked cruise on 65 mph and got 20.3. Return trip locked it on 70 and got 19. Was strictly the interstate miles. I reset the computer at the on ramps. Pleasantly surprised. Not bad for and engine not yet broken in.
I have a 2012 with the 4.6 I get average 17.7 on light city.going easy on the highway I can get 23.but it's keeping under 70.over 70 its lunch time.back around 21.driving habbits make huge differences
Damn I gotta 2008 Tundra 4x4 SR5 4.7 that gets 12.8 mpg. Looking into the k&n 63 and 77 for better mpg, noise, and performance but i can't decide which to go with.
I had the Tonnonue , spelling, cover on my 14 model and got 23.3 mpg on 87 oct. With the cap, looks like a SUV now but got 21 per gal. The flat cap was the best gas milage one. You must drive like I do a little. I would use the just cover but like a Cap instead. I am wondering what would happen with 89 oct? Think I am going to try it. I know 93 wont work , over kill..
You did not fill the tank all the way. The gasoline foams and shuts off the nozzle. You need to let the foam settle, then fill slowly until the nozzle clicks off. Gas station pumps are made for safety and to collect fumes. Not for accurate mileage tests.
my 2007 bone stock 5.7 2wd double cab got 20 mpg. My 2010 5.7 4wd crewmax with lift and 34" tires gets 14mpg. I'm pretty sure his was all interstate miles also
Notice below. I also used a K&N filter on the truck. I think that is a big deal for easy flow air and no cold air system. I don't believe in Cold Air Systems. More noise than anything else.
The factory already installed a cold air system for us! Air comes right from the fender, not inside the engine (cold air)! I have the cover and the exhaust and still only get 14 average.
Notice he has a tonno , spelling , on his truck. Big deal with that. He also uses Shell gas. I got 23.5 on a trip to S Carolina and 22.4 on the way back to Fl. Also the same setup as he has. It has to be the cover and the brand of gas he used as it was the same brand I used on the trip.
I totally agree! I fell for the "Build Tough" advertisement by Ford. All I can say is build tough my ass. It's about time I stop supporting the big three and get a Tundra.
Proves a Tundra 5.7 with clean air filter can do better than advertised. Some just don't believe it. I have gotten 23.4 doing the same on a trip using speed control and using good gas.Shell on my tundra works best by at least 2mpg. Anyone don't believe me, let me know.
Thats a myth all gas is the same just different additives... but at the end you are still spending more on “better fuel” than what you couldve added extra onto your truck at cheaper gas station.
I have a 2007 Tundra with a 5.7, I put electric motors on each wheel and a big solar panel for a box cover, then I put a windmill on the roof and now I get 25 M.P.G.-it's totally SIK.-Al GORE showed me this set up !!!!
