Gas mileage 5.7 vs 3.4

Was that with winter gas?? IDK, but I get ~20 in my normal daily driving that is maybe 75% highway or back roads and 25% suburban. At least on summer gas and mostly unloaded. I expect a little better on a pure road trip. I don't bother to check it in winter what with winter gas and cold warmups.

 

First trip was last August, second trip was last month. So I don't think fuel blend had anything to do with it. Both trips were 95% interstate driving 65-75 mph. Idling stops for food and fuel averaged around 10 minutes. On our recent trip, I did hit about 6 hours of heavy rain on one leg, and about 1-1/2 hours of stop and go thru Atlanta on the return leg. (did I mention I hate that city?)

IDK, I'm not an aggressive driver at all. I'm easy on the skinny pedal and the brake. I've tried Eco and Normal driving modes with no noticeable difference in mileage. Don't get me wrong, I didn't buy my truck for the mileage, but it would be nice to get over 20 like some of you claim to.

 

Possible the load dropped the tail enough to hose the aerodynamics?

 

It was just typical vacation luggage. Not heavy at all. Didn't notice any squatting. My 2015 Tundra would average around 14.3 on the same trip, so my new truck is an improvement, but nothing to toast about.

 

That is still a 19% improvement. Pretty darned good IMO.

 

I seem to get worse mileage in eco mode. 17-18. Getting over 19.5 in normal. And that’s with the occasional swap to sport mode for the on-ramp

 

65 and under is where it shines for me, especially the Hybrids, once over 70 It seems to be a crap shoot. Great for us Canadians as the majority of roads I use are in that 60-70 range.

I don't rely on Fuelly as I have zero knowledge or info on how everyone drives, at what speed, downhill / uphill, running from the Po Po, stock tires, or 37's ......so you can't compare your driving habits to some random fuel forum. Kinda need to figure it out with what/ how you drive

 

Get at least 5K miles on it before you even bother to track mileage, or you'll be disappointed.
Mine took a BIG jump around the 3K mark.

It's all pretty simple physics. Weight, aero, and boost are not conducive to good fuel economy.
How to get consistent, decent mileage with a 3rd gen Tundra:
(As always, IMO, YMMV.)

1. Stock-ish weight wheels/tires. E-rated 34" and bigger tires and bigger/heavier aftermarket wheels will generally take a 2 to 2+ mpg hit.
2. Don't haul or tow anything. (Stay out of boost.)
3. Don't bother with ECO mode with anything other than highway cruising. It has been shown that your mileage can actually suffer using it for city driving.
4. Don't exceed 65 mph if at all possible. Punching a big brick through the air takes more gas the faster you go.
5. Stay out of Tow or Tow+ mode (goes with #2) Unless your goal is a one-wheeled smoke show, then go for it.
6. Adaptive or whatever it's called CC...don't use it. Brakes too much. Use "normal" CC instead.
7. Don't drive like a maniac.
   
   Getting a consistent 21-22 commuting to work 12.5 miles each way. Pretty happy with that.
   2 lane county road, 62-63 mph, normal (not adaptive) CC in use.
   

 

I have never understood why anyone who buys a TRUCK whines about the friggin MPG. These are NOT honda Civics. I bought mine because I value the 381 horsepower and use it when I need or want to. If one needs to baby it to get that extra 5% better mileage, re-evaluate your mission and change vehicles accordingly to satisfy your gas mileage goals. Another suggestion - KEEP IT STOCK as far as running gear, etc. if MPG is that important.

Okay, back to your regularly scheduled program.

2011 340000 5.7 17.5 mpg consecutive stock 10 ply tires is all 350 mile on 20 gallons. Really happy. Been running those number all on the highway run 14.5 in the city.

 

Mine didn’t. Mileage never changed. Just always good.

 

That’s exactly right. Cars in the 90’s and early 2000’s were built to meet lesser requirements and got better mpg in many cases.

 

We drive slower. I can get 17 too if I drive 80 and out the peddle down every now and then. When I’m cruising normal highway speeds around here of 65 I get around 21 with after market tires. Towing my 4000# boat I get around 14.

 

I hear you, but it’s only because these numbers are so low that +3mpg is a ~20% improvement. We’re still all driving 6000 lb Lego bricks.

And yes, @Hella Krusty, Fuelly is a reliable source of real-world fuel efficiency that paints a far better picture than EPA estimates because Fuelly is nothing more than a statistically viable sample of people all driving the same vehicles. General trends emerge and are accurate.

 

"All over for $500, Alex."

Never cease to be amazed by the Gen 3 fan bois.....
for the rest of us prudent, pragmatic Tundra fans 2025/2026 can't come soon enough for these trucks.

 

I drive an F150, but am a fan of Toyota as a whole seeing as i came from 2nd and then 3rd gen Tacoma.
I can’t imagine OP coming here looking to engage in civil discussion laying down phrases like “I can't imagine any of you are happy with the brand”
Thanks for stopping by and playing Frank, we’ll see you 2025/2026

 

Whatever the case, I hope so. The '24 full-size truck market is an overall disaster right now. With Nissan canning the Titan, there is no truck produced that comes remotely close to the reliability we've all come to expect from pre-'22 Toyota.
Toyota has to get this figured out, I refuse to think that it's beyond hope. Forty five years of loyalty is a long time.

 

As cliche as it may sound, I have hope that Toyota figures this out, the alternative may prove to be disastrous for the company.

Looking at their history, I don’t think im being naive.
Or these could be famous last words hah

 

2018 platinum 4x4 5.5ft (249 full ups) vs 2023 platinum 4x4 5.5ft non hv (48 fill ups)

this is for gee whiz info, we dont care about the mpg.

 

The superduty in my experience is pretty damn reliable.
