Fuel economy of the new 2022 tundra

2022 4x4, stock, regular gas, not high elevation. 21.4 avg highway, 19.2 avg rural/city. Glad I got the 2022.

 

In the 80's I had a piece of crap Camaro Z28 and the 350 cubic inch GM 5.7 liter with the H.O. designation for high output advertised 190 hp.
And it got 12-13 mpg.
I think that I can average 17-18 mpg with a 5500lb brick loaded up and it has a 5.7 liter putting out close to 400 hp is quite remarkable.

 

My 2010 5.7 has the towing package (most did) which has a 4.30 rear end…I routinely drive it to town on county backroads at 45mph and can get around 15mpg but it’s illegal to go this speed on most highways in Texas. It was built in 2010 for the speed limits in 1973.

Fords hybrid does little better per fuelly’s stats…their hybrid F-150 averages 18.8mpg (123 drivers; 1600 refuels, 673,000 mi)

 

My 5.7 on stock wheels and tires consistently put down 15.1 MPG in cold winter weather on winterized fuel. In the summer it would be a 16 MPG truck. My weekly commuting is pretty much a 50/50 split of city/highway.

These little engines with twin turbos generally will see about a 15% improvement over a V8 when commuting. The drawback is that when hauling/towing they fall about 10% under a V8. (This is going off Ford numbers since they've already been doing this for 10 years.) And we buy trucks for a reason, right?

And, don't the turbo engines usually require higher octane fuel?

So when it's all said and done, fuel $$$ is pretty much a wash between V8 and V6TT.

 

All 5.7's came with the 4.30's. And that doesn't mean much. The 4.30's were needed because the transmission gears in the 6 speed are insanely tall. Literally, an old 6 Speed F150 with 3.55's had shorter overall gearing than a 2/2.5 gen Tundra. An now with the 10 speed, even 3.15's offer a shorter overall ratio than a 4.30 tundra.

 

All mpg ratings are done with flat highways. Keep apples to apples comparisons.

 

C'mon man, anecdotal much? Generally ..usually ..pretty much....You guys slay me.
Some of you fellas have gotten high on your own Gen 2 supply.

 

Only if you live in your world of false assumptions and vague murmuring. Regular octane fuel for the 22. But I didn’t get it for the fuel savings (which is good), I chose the 22 for more horsepower and torque than the 21. Among other things.

 

Turbo engines are extremly sensitive to driving habits, moreso than an NA engine. In my wifes old supercrew , when i drove it i always got 16 mpg, when she drove it, never better than 12.9 sometimes dipping as low as 11.9 . Its alot like two stroke dirt bikes being either on the pipe or off the pipe, theres not much in between the two worlds of on the boost or off the boost

 

It depends on the engine load. My Ecoboost can run at MBT(maximum brake torque, timing at which maximum torque is created) under light loads on 87 octane. But once you start to ramp the engine load up it will start to diverge and timing will have to back off away from MBT. Even on 94 octane my truck is not anywhere close to MBT at higher loads. In an Ecoboost, and the Tundra, you basically need E85, which is like 100 octane, to reach MBT in all conditions.

So basically, the advice in the Ford manuals is actually pretty good. 87 works, but if you are towing or abusing the truck they recommend using higher octane fuel. Towing a travel trailer you spend the entire drive pretty much at timing less than MBT. The more octane you run, the closer your truck will be to MBT.
