The Tundra drinks gas because....

Not much worse than the 3.7 in the ladies liberty... But can the liberty haul half a ton? Is it this fast? Tow 10k? I mean cmon yall...

Thats how the government does it. Buy/sell/trade carbon credits. My truck is allowed to make a black cloud because my wife drives a hybrid. "It offsets blah blah blah"

 

I’d love to know why it sucks gas

 

I get real good fuel economy with my Tundra. If you only drive it 5000 miles a year you will too

 

It drinks gas because it obviously wasn't the primary consideration at literally every point of the design process.

-Large engine built with enough airflow capacity to make good power over 5k rpm, but only cam phasers to mitigate the shortcomings. No intake valve disabling like a Honda D15B or L15A1, no port/injector disabling like an LT5, no variable valve lift like Toyota's VVTi-L 2ZZGE engine, no cylinder deactivation, nothing that increases intake manifold pressure or port air velocity at cruising speed.
-6 speed automatic transmission made with tall ratios but containing as many planetary gearsets as a 10 speed. More parts, more friction, and a hydraulic pump holding over 200 psi. This is why the old Civic VX with its 50+ mpg had a 4 speed stick.
-Also the programming. It doesn't even allow converter lock in drive until 5th gear. Drive a Toyota car with an automatic before they got CVTs. They're locking converters by 25 mph in cases and forcing high engine loads under 2k rpm. Tundra upshifts at 65% load... but it feels sportier. Otherwise people parrot off like Chevy truck drivers--- "it feels like it's lugging all the time"
-Truck body as wide as legally allowed, with a 6'4" factory height. Big cross section. Aero? Well there's those little diffuser tabs on the taillights I guess. No air dam underneath. No smooth panels on underbody. No automatic grille shutters. No auto lowering suspension.
-Everybody blames the 4.30 gears but the transmission is so tall it's like a Ford with 3.73s. Still, huge gear, big bearings, drag.
-Accessories and fan drag the serp belt just like they did when Reagan was President.

But it runs and runs just as long as you feed it

 

Lol, I was gonna post the exact same thing. I went from about 80 miles a day to sub 10

 

I'm new to truck ownership. I bought an old airstream first.. then needed a truck to tow it. Tundra was my choice because it was engineered to do work, and has the reputation for longevity (if cared for). Happy to fill the tank knowing it's going do what I need it to do, when I need it to do it. It's not a commuter. It's not a grocery getter. That being said... I drive it like a great-grampa... super slow of the line, and I can get 15-16 around town and got nearly 20 on a 1300 mile highway trip.

 

It's all good - we all love our Tundra's but it doesn't mean they don't have weak points. I just towed my camper this weekend and experimented with towing in just S4 (with T/H on). I haven't done this yet because I was concerned about what it would do to gas mileage, but I wanted the lower trans temps others have reported when towing in S4 w/ converter lock-up. I was really pleased to see the dash computer report about a 13mpg average (however accurate that is). I expected much lower.

Yep. S4 is where it’s at for towing. 5 and 6 are overdrive gears. If you want higher transmission temps, worse fuel economy, and worse engine braking, tow in S5 or D. My favorite thing is reading about people complaining that the Tundra hunts for gears when towing in D at 75mph.

 

I get 11 MPGs with 37s and love every minute of it. I didn't buy my tundra to save gas.

 

I always thank Telsa drivers for making up for my horrible MPG.

 

430 rear end...

 

Why does my tundra drink gas?

 

Yeah, but that's what makes the '07-21 tundra the most reliable half ton pickup ever built.
