2018 Toyota Tundra 5.7L 4X4 Highway MPG loop. Better than you would think! Tundra Miles Per Gallon

Here is my Miles per Gallon (MPG) loop in my 2018 Toyota Tundra sr5 Crewmax Sport 4x4 with the 5.7 Liter v8.

This truck normally gets around 13.5MPG, but when i drove the truck at a constant speed of 70mph i got 16.778 MPG. That isnt bad at all for such a large capable vehicle.

Toyota Tundra owner for life here! I love the truck, i love the way it drives, the way it looks and the way it sounds. The reliability and resale value are just bonuses.

My 2017 TRD 4x4 5.7 FF with a S&B cold air intake and a bullydog tune on 91 I average 20 - 21mpg on my commute to work. Relatively flat roads, 50-55bmph for first 1/3, 75-80mph 2nd 1/3 and 50ish last 3rd of the trip. Flat Arizona roads driving conservative. It seems like anything over 75mph and these trucks just start sucking down the fuel. My best commute was 22mpg.
I usually drive with tow haul on as well. If anyone cares to know.

My 2018 Toyota Tundra SR5 Crew Max at 55 m/h sometimes gave me up to 24 m/g....On the highway and loaded with 900 lbs at 70 miles using cruise control gave me 19.9 m/g
Happy camper here.

Has anyone thought about changing the rear gear Ratio. Or has anyone changed the gear ratio to see if that improve the tundra mpg

I recently bought a 2016 SR5 4WD DC. I have the original tire size. I did my first test for all-town driving (many suburban traffic lights and no freeway). I drove like an old lady with a very light foot because I wanted to see how good I could get. The dash gauge said 12.0 MPG, but I did the math ... 10.75! Luckily, I have a small Mazda for around-town driving. I'll be taking a road trip in a few months with 400 miles of all freeway. I will only drive 60 MPH. This fugger better get at least 15 MPG, or I'll be seriously bummed. I knew the Tundra's gas mileage sucks, but not this bad. Every car/truck I've ever owned got what the sticker said it would get. This thing is supposed to be 13 in town and 17 on freeway.

As long as the roads are fairly flat, mpg isn't too bad. I drove my purchase Tundra from Hartford, CT to MN. Through hilly NY and PA, i got 16ish mpg, through OH and IN, i got 18ish because of flatter roads. Highway speeds around 70mph.

On flat at low altitudes all stock 4x4 cm 2018, my range is 12 to 19 depending on driving styles. Keep up with others on the road for 12. Go slower than school buses for 19. You can stay at 19 and say Tundra's mpg is not bad.

Ill get 19-20 if I really keep my foot under control. Like really letting off a bit on hills and such. If i just drive without thinking I get around 15-16 with a 60/40 mix of city highway. I did a 250 mile loop yesterday. The first half was unloaded just me and the family and got 19.6. Then we picked up and loaded a uhaul trailer(maybe2500lbs) with some idling and such and when I got home it said 16.5. Not too bad

This has been the typical MPG since 07.

I have a 2020 Tundra crewmax 4x4, 20 inch wheels 275 wide by 70 tall.
On 87 octane, hilly terrain with about an hour of flat driving at 64mph I was getting 16.2mpg. Best I’ve got is 18.2. I only drive it about 100-200 miles a month though.

I've always tracked my mpg's very closely on my vehicles every fillup. I have a 2018 CRV that shows a computed mpg on the dash. I was always skeptical of it, but over time I've become confident in it. Probably the reason what you calculated is a bit less than what the truck says is due to when the truck is calculating it the time you are sitting in stop lights and not moving is not considered. The truck is calculating amount of fuel used during movement and what you manually count included the fuel usage when not moving.

[dalephillips]

You've got larger than stock tires on your truck as the GPS reading is more accurate than the speedo.

[mattlaw]

Does your truck have the 26 or 38 gallon tank?

Tundras poor mileage is a bit over exaggerated. I’ve own 2 and they got as good or better than the domestics V8’s until later years when the domestics came out with their 8-10 speed transmission. Now my Tundra gets around 2 mpg less from my experience. V8’s. But I still have the tundras reliability

[geanitsucuneli]

I do own a Tundra V8 ...5.7 L- is a 2021 4 doors Long bed.My advise is buy Shell, you will get better miles/gal and the engine runs smooth .

[JacqueDuck]

My 07 Tundra Limited RWD got 20 MPG w/ Cruise @ 68/69 MPH last trip - Only Limited By Ones Imagination- Grumpy Old Vet- Max 26mpg. W/ 5.7L V8 - on All AMSOIL Lubricants in engine, Transmission, Rear Differential.

Summer on my 2019 TRD Sport Tundra I get 14.2 litres per 100kms. With TRD cold air intake. Winter forget about it. It’s like 16.8. I’ll definitely try to turn off traction control see what that’s does. Cheers

[prw]

I own a 2021 tundra and a 2019 f150 5.0. Both get around 15 mpg with me driving 80hwy. No big mods, AT tires and the ford is leveled in the front only. Other than that they are stock.

[septimustyrannis]

I’d like to know what size tires you have on your tundra?

[faridgadimov]
