I’ve Had My 2025 Toyota Tundra SR5 Off Road Package For About 2 Months, and I’m NOT Loving the 230 Mile Range On a Full Tank

A 2025 Tundra Owner is not happy: Adrian Olivares is getting just 230 miles per tank. Is this the new Toyota Tundra norm or a personal problem? Owners are talking about range, regrets, and whether the Tundra is too thirsty. What owners need to know.

Two months in, another new Toyota Tundra owner is already sounding the alarm: Is a mere 230-mile range on a full tank a dealbreaker for the redesigned pickup?

Adrian Olivares on the 2023-2026 Toyota Tundra Owners Facebook page says, 

"I've had my 2025 Toyota Tundra SR5 Off Road Package for about two months, and I'm NOT loving the 230-mile range on a full tank." 

Is the Tundra too thirsty?

Adrian spent good money on a rugged, capable new-generation Toyota Tundra, and he expects it to deliver reliable performance, which includes a decent driving range. Seeing only 230 miles to empty on a brand-new 2025 Tundra SR5 Off Road Package is a tough pill to swallow, mainly when Toyota sold him on the highly efficient twin-turbo V6.

What Adrian is experiencing is not unique. It's a common—and often misunderstood—challenge facing many new Tundra owners. I've tracked these third-generation Tundra mileage complaints since the 2022 launch, and I know where the problem lies and what owners can do about it.

It's the Fuel Tank Size Disparity

When Adrian and other owners bought an SR5, you likely assumed you had the largest fuel tank available. Here's where the confusion originates: the real-world fuel tank range for new Toyota Tundra owners hinges on one overlooked specification. Toyota offers two fuel tank sizes: the standard 22.5-gallon tank and the much larger 32.2-gallon tank.

The 32.2-gallon tank is standard on the Limited trim and above and often requires specific packages (such as the CrewMax configuration or a convenience package) to be equipped on the SR5. If your truck is averaging 17 MPG (the EPA combined rating for the 4x4 SR5) with the standard 22.5-gallon tank, you should still be getting around 382 miles of range. Hitting 230 miles means your real-world consumption is hovering around 10.2 MPG, which is genuinely concerning and suggests a triple threat: small tank size, aggressive driving, and the Off-Road Package itself.

If you don't have the 32.2-gallon unit—and given your range, it's highly probable you have the smaller tank—that compounds the impact of minor fuel-economy dips. This is the first, most important discovery: check your spec sheet or fill-up volume.

Why the Off-Road Package Eats Fuel

Beyond the tank size, your specific package configuration is a key culprit. The "Off Road Package" typically includes larger, more aggressive All-Terrain (A/T) tires and potentially heavier wheels. Here's a quick breakdown of how these components work against your MPG:

  • Rolling Resistance: A/T tires are heavier and have deeper, blockier treads that increase friction and rolling resistance on pavement. This forces the 3.5L i-FORCE V6 to work harder to maintain speed. Do larger tires significantly hurt Tundra MPG? Absolutely, they are often the silent thief of 2 to 3 MPG right off the top.
  • Aerodynamics: Your rig is built for breaking trails, not cutting wind. The blockier front end and slightly higher stance inherent to the Off-Road trim create more drag. Sustained speeds above 70 mph will exacerbate this problem as aerodynamic drag increases exponentially.
  • Turbo Lag & Lead Foot: Toyota designed the new twin-turbo engine to be powerful. However, every time you tap into that 479 lb-ft of torque for a spirited acceleration, you're pumping premium fuel straight into the combustion chambers. This brings us to the most actionable solution for Adrian and others who ask: Why is my Toyota Tundra's fuel economy so bad?

Here are four recommendations for boosting range, assuming you are stuck with the 22.5-gallon tank for now:

  1. Tire Pressure: Check your tire pressure weekly. Underinflation by just 5 PSI can directly translate into reduced fuel economy and poor handling. Stick to the manufacturer's recommended PSI on the door jamb sticker.
  2. Modulate the Boost: This is crucial for optimizing the twin-turbo V6 for better Tundra efficiency. Drive in ECO mode for daily use. Focus on feathering the accelerator and staying out of the turbo boost range (listen for that quiet "whoosh"). Smooth, gradual acceleration is your best friend.
  3. Unload the Weight: Remove unnecessary items—toolboxes, gear, recovery bags—from the cab and bed. Less weight means less strain on the engine.
  4. The Engine Break-In Myth: Many owners report that their Tundra's fuel economy improves noticeably between 5,000 and 10,000 miles, as the engine computer fully learns their driving profile and the drivetrain components settle in. Give it a few more months before panicking.

What the Community is Saying

I'm constantly monitoring the forums and social media, and the consensus on this issue points to the core truth we discussed. This is the 2025 Toyota Tundra's poor gas mileage range solution everyone is discussing:

  • @TundraJoe33 recently posted: "I thought I had the big tank, too! Had to drop my spare to confirm I only had the 22.5 gal. Switched to my 'grandpa driving' style, and my range jumped from 250 to 320 miles. It's the lead foot, folks!"
  • @DesertRunner mentioned: "My How to improve Toyota Tundra SR5 Off Road MPG discovery was switching from Mud-Terrains back to a less aggressive All-Terrain tire. Instantly regained 2 MPG on the highway."
  • @HighMileageMike advises new owners: "Do a manual MPG calculation every fill-up. Stop relying on the dashboard computer for the first few thousand miles."

The driver and the tank size are the two variables within your control.

Conclusion

The bottom line is that the new Tundra is a powerful and capable truck, but that powerful twin-turbo engine requires disciplined driving, and the choice of fuel tank size right off the lot dictates your range.

I sold Toyotas and was also a sales mgr for 16 years. No one had to convince me about Toyotas quality & dependability. I drank the Kool-aid and enjoyed every drop. I special ordered my dream truck. A beautiful 2025 SR5 Crew-Max with every available option I could get. I was in love and loved showing it off. Unfortunately the Max max milage I could get was 11.9. I tried every single option listed above. I didn’t want to rely soley on the vehicles computer and did my own consumption calculations. Turns out the trucks computer was accurate. I gave it 5 1/2 months and realized I was spending slightly less in gas than the truck payment itself. Unfortunately I had to stop the blood letting. I traded it for a 2025 Silverado Z71 with a 3.0L Duramax diesel. My max mpg has been 32.9. Yep, 32.9 that’s not a typo. My average is 19-23. Admittedly I love everything else about the Tundra more, but I couldn’t ignore the milage disparity and the Silverado is still a very nice truck. I would recommend at least taking a look.

2024 Toyota tundra 32 gallon tank 430 miles around town. Don’t cut it any slack. 7000 miles now . And I wasn’t on empty when I filled up. Love fuel economy/ Chevy had to fill at 300 miles and cost the same or more. And I didn’t run the crap out of it . And mine is the 4/4 xp edition. Noticeable improvement in fuel economy. Getting away from Chevy and useable power. Chevy all i have ever owned until now. 40 years finally tired of fuel mileage

If you had to drop your spare to find out how big your fuel tank is you need to turn in your man card. And if you are not intelligent enough to figure out how many mpg your getting you shouldn't have a drivers license. It drives me crazy when people want to talk about how many miles per tank! If your tank is big or small you are getting the same mug! 🙄

Well I am getting avg. 17-21mpg in the hills of WV in my 2025 sr5 tundra. Gas mileage was around 12-14 until I put over 6000 miles on it then started going up a lot. Currently have 8900 miles and seems to be settling in 17-21.

Laura (not verified)    November 1, 2025 - 5:52PM

It is a shame to hear that Toyota hasn't improved the mileage in a decade. I was looking forward to upgrading my 2015, but if the current is no better, then what's the point?

I have a 2022 Tundra Limited with a 7" superlift as well as 35" Toyo open country tires and i average around 14 mpgs. I do use a Banks pedal monster which doesn't improve fuel economy but makes acceleration better. Love the truck!!!

I owned a 2024 Tundra Platinum edition and was very very disappointed in the fuel economy. Why have all that power and drive in Eco mode? Around town, eco mode got me close to 15 miles per gallon. On the highway closer to 17 in Eco mode in normal and/or sport modes, average around town was 13 and 14 on the highway. Horrible based on what other full size trucks are offering! And not much of an improvement over the V8 Tundra. If it wasn't for the 32 gallon tank, I would have been filling up every second to third day. And don't get me started on the lack of range with remote start. You have to stand right next to the vehicle to start it and when you open the door it shuts it off. Why? Unlike every other major manufacturer. And last, the seatbelt tone is obnoxious, incessant, so I had to buy a seat belt tone canceler (see Tikit) to go in the buckle for the times I had the vehicle off-road and did not need my seat belt on.

It shuts off for security, my Lexus does the same thing.nwhat if it's not u that opened the door, they could drive it till they shut it off or run out of gas. I've left the key on the counter and drive over 50 miles with the thing so it doesn't need the key once it is started so if u went back inside to wait for it to warm up anyone could climb in and drive away!!

The title should read: “Poser buys pickup truck with off-road package and no plans to tow or throw anything in the bed—complains about fuel economy despite buying a vehicle that shouldn’t get very good fuel economy in the first place”

Hi, I have a 2024 Tundra sr5 double cab with 8ft bed. I have the 22 gallon tank. At 55k miles I'm getting 370ish miles per tank. And I haul a lot if heavy stuff bc it's a work truck. And I crush it accelerating couple times a day bc how fun the twin turbos are. Brand new I was getting 360ish miles per tank.

I have a 2008 Tundra 4 x 4 with a 5.7 and a 4.10 diffential, It averages 17.5 mpg. Add a cab high for my hounds and larger more aggressive tread and 10 ply tires,
280k miles, still getting over 15. All Toyota had to do was go with a higher ratio diff with the 5.7 and they would have won the game. The 5.7 had plenty of power for that. Turbo are just something else that will fail and need rebuilding. Smaller harder working engines are not the answer in a truck, just my 2 cents. I love my Tundra, my next truck will be a pre-2019 Tundra or a Chevy, maybe even a restored 1980's F- 150 w/ a 300 I-6. All in 4 x 4 of course.

Its Sad Toyota doesn't offer a basic 2.3l 4 with Turbo for fuel economy, I have an 83 with a 22R that I rebuilt with a Low Range Camshaft, That's Power in the 2400 rpm then 2800 then 3200 not the Nothing untill 3400 like the regular cam. I get a Nice Jump off the line and higher gear quicker too with 26 mpg.
Reminder, this is a 22R with Later model EFI and OBE2 plug, so this Later computer manages the fuel to sipping. And a Six Speed manual too, Sometimes Toyota makes people BUILD it Themselves!

First off. If you buy a full sized truck gas mileage is not usually a primary concern. Especially when you opt for the the off road. You want economy get a hybrid suv. Tundras are shit, built like shit, drive like shit.

There clearly is something wrong with the system in their trucks. I've had two different years about 6 years apart of different brand/model vehicles both with towing packages and whatnot. They were both same exact models. They had exact same tank sizes, and a number of other similarities. I basically drive the same way on similar roads, so there should be little to no difference between the two. The earlier one I peaked at about 23.4 mpg at times (which had a manufacturer estimate of 17 to 19 mpg). The newer one (which had a manufacturer estimate of 18 to 20 mpg) I struggled to get to 19 mpg a lot of the time, and many times was between 18 & 19 and on occasion between 17 & 18. Managed to get it to 20 mpg a couple of brief times, but they were likely unusual times. I was exceptionally disappointed with its performance. Turns out there's been loads of sensor glitches on a wide variety of things over the years that progressively got worse. Essentially showing the manufacturer likely had cheaper parts issues, bad wiring - bad grounding - poor insulation issues, etc. Basically need to continuously complain to the manufacturer again and again and again... Keeping track of every tiny little glitch and any other issue you can note, and getting multiple checks from different places (not just a dealership).

Their problem should be resolved through checking numerous parts and how cheap or poorly they were made and/or poorly installed, as well as how poorly they were tuned into everything else.

If that’s all you have to bitch about, go trade that mother in for a Ford, Chevrolet, or Dodge. Then you can complain about all the time it is in the shop with an assortment of problems.

Mike Cartwright (not verified)    November 2, 2025 - 11:19AM

You also need to realize that the system has a 5-6 gallon reserve when the dte shows 0. The reasoning is to cool the fuel pump. I have 23 limited and usually avg 16-17 in all around driving and can push 20 mpg on interstate driving.

...I bought a big jacked-up pickup truck with the largest tires available l, and I can't figure out why my gas mileage sucks. Please help!...

Tell me you are clueless without telling me you are clueless.

I have a 2025 Toyota Tundra SR base model with 4x4 extended cab. Only have it for 4 months with 3800 miles on it and I’m regularly getting 21 miles per gallon. Also have the small tank. Would have preferred the larger tank but didn’t even think of that at the time.
