Testing Highway MPG On A Tundra With The 5.7L V8! (169,000 Miles) 

bullet proof 5.7L engine

Thanks for putting this together. I have an '08 DoubleCab with 163K miles, 5.7L. Just put a new fuel pump on it, I get 17-18 mpg on the highway, maybe 200-300 lbs. in the bed, not pushing it much over 70 mph though.

We have a 2018 SR5 Crew Cab with the 4.6L. 139,929 miles. When our son comes of age he’ll be driving this. ❤👍🏾

I just bought a 2010 RCSB with the 5.7 and 4x4 and the first tank I ran through it was 15.5 MPG. It sounds like these things are pretty consistent with their fuel mileage to me.

My 2010 Crewmax 5.7L (112000 miles on truck) TRD got 18.4 mpg driving from MD to FL, doing the speed limit and cruise control. *Stock 18" wheels and tires. The think it helps to accelerate slowly and maintain tire pressure..

I have a 2017 5.7 crewmax 4x4 with 33" tires I get 14 city and anywhere from 17 to 19 on hwy just depends on wind and hills

2020 Crewmax 4x4, 20” wheels, 285 mildly aggressive M/S tires. 2.5” leveling kit, 19mpg@ 65mph, cruise control, From Sacramento to Red Bluff. Consistently but I also stay below 2,000 rpm even taking off from a stop sign. If I want to go fast I have a built turbo diesel at home.

Just bought mine 2 days ago, my last one was a 07 Toyota matrix, it’s like going from a bathtub to jackuzi. 😅

I have 2014 Tundra and I find that 60mph on the highway is the magic number for good mpg. I usually get 17's to 18's on the highway. I have an aftermarket AFE air filter and a tonneu cover which I found that the combo of both of those overall raised my mpg by about 1.5.

2016 tundra crewmax, 113,000 I get around 9 to 10 mpg in town and between 19 to 20,21 mpg. I was getting worse gas mileage but used ATS Chemical oil and gas treatment and now get the in town/ highway, and I get even better gas mileage at 55/60 mph. Above that and she drinks like a sailor ! Lol

I have a 2008 Toyota Sequoia sr5 4x4 with the 5.7. I usually take a 4 hour trip from brownsville to San Antonio, Tx. I fill up before i leave and get over there with half a tank. Not bad for a big monster V8. I use cruise control all the way and stay at 75 mph.

That's pretty good. I have a 11' f150 2wd regular cab with the 3.7L and I don't drive hard. I only get 18-19 mpg per tank. 😕

I get 17.5 -17.8 quite often with my 21 tundra. I’m in Florida where the terrain is flat. That might help you in OK as well. The big thing is paying attention to how you drive.

Nice. I get 16.2 on highway. Also I have a full ranch hand bumper - trying sell that and get better tires.

2019, 5.7, 34” X 11.50” Grapplers. Get 14 in the city and 16 on the highway.

I have 07 double limited 2WD 5.7 with 151,000 miles, the same front spacer to level and Cooper 295/70/18’s, K&N filter. Mostly city driving average 14 mpg. If on highway, I get 17/18 also. I love my truck.

When my 08 was on stock tires it did between 17-18 on the highway. 14-15 city. Now 8 inch lift and 37s I get 11 and 13.5

I have a 2008 Double cab with the 5.7. On my drive through the mountains between BC and Alberta, I averaged 12.9L/100km, which translates to about 18 mpg. I've got 140,000km on it, and was averaging 110kmh

I bought a 2008 crewmax 5.7 4x4 new and now have 342k miles everything is stock besides right front wheel bearing and bank 2 catalytic converters , its pulled a trailer for about 90% of those miles between 4 and 9 thousand pounds . I dont drive it easy at all ,notmally floored to get on highways and on highways im going about 80 towing. Depending on weight i get 6.5-10 towing and with out trailer i get around 14 mpg

I have the exact same year, cab, motor, and color. Mine just has a cap on the bed. Just got it with 174k. Haven’t made any long trips with it yet but will find this video and leave a comment when I do be interesting to compare.

I average 18.2 m per gallon in 2018 crewmax sport with just over a 110000 miles on it with a hard bed cover and that makes a difference

Thanks for the video. i have a 16 DC with the 4.6 V8. I found this truck new fro 28K so couldn’t pass it up as I was looking for a used tundra this new one was not much more than used at the time. Mileage is around 12mpg in town on highway it varies highly on speed I’ve gotten 21 mpg driving at 60 mph and then 10.5 mpg doing 80+. The transmission is constantly searching for a gear on cruise control which I can’t stand so no cruise control unless it’s flat highway. I remain a Toyota fan

Just Purchased my RWD 2007 Toyota Tundra Limited CrewMax & on my First Tank of fuel- Trying Archoil & AMSOIL OW20 oil we’ll see what it does. It already impresses in the Performance arena- Grumpy Old Vet! Tundra Texas Edition 5.7L V8 running great At 143K.

2021 2wd crewmax has gotten as high as 21.5mpg on the highway which blows my mind. That was hand calculated too. Usually driving 70-75 I can pretty much get 18.5-19.5 consistently! I drive 90% highway too though

I've got a 2014 (1794) with 181,000 on it. I get 15 combined and 17-20 on the highway depending upon the wind. I you're using non-ethanol gas as well as a tailwind on that trip, I'd think you'd get even better mpg. I've been researching the new generation Tundra and as much as mines been bulletproof, I'm not convinced the new gen is much (if at all) better other than the bells and whistles part of it.

Mine is 2011 double cab 4x4, 5.7 with soft tonneau cover I average 17.5 mpg commuting back and forth to work. Which is 50 miles round trip.

The 4.6 engine w the 4.10 rear end was always around 19-20 mpg for me but 2wd .

17.8 MPG, not too shabby

2021 trd pro tundra with michelin defender ltx ms tires. City avg 14.5 to 15.1. Hwy 17.1 to 18.5

I got 16.3 ish while doing interstate driving @ 85mph. I can see 17-18mpg if i followed the speed limit. Running a 2wd crew cab, no mods except airfilter and airbox inlet mod.

2012 sequoia 5.7 4×4 stock 17 mpg 15 mpg

That's way better than I get. I've only been getting 8.2 mpg. Something's wrong. When the truck was new, I almost got 20 mpg. Mine is a 2008 4wd 5.7L dbl cab with over 265,000 miles on it.

2007 Tundra 4.7 liter, 26 gallon tank. Drove from ST Louis to Chicago and couldn't make it on one tank. 285 miles and I had to stop around the 240 mile mark for fuel, so about 12MPG?

i gotta 2007 tundra running a 4.7l v8 and i’m averaging like 11mpg, also has a bed cap on the back too but it’s not too heavy

i have a 16 crewmax 4x4 with the 5.7, use 85 or flex fuel, and get about 18mpg on colorado highways. your number seems very reasonable.

What size tires do you have exactly?

Sounds about right but you probably got better mpg than that as you have 33in tires which will make the odometer reading less miles than you actually traveled. That is unless you've had the speedometer adjusted for those tires

2017 5.7L 4x4 DC on stock sized KO2’s. I get 17.8mpg doing 65mph. Going 70mph and it drops off fast.

4wd 2010 tundra 5.7 double cab. I average 13 most of the time.

Mine is 2010 tundra 5.7 double cab got 25mpg. no ac, at 65mph with low profile tire on rim22

I have a 2015 Tundra and my average is 15.6 MPG.

Good relaxed vid & helpful - decent mpgs for the power & torque of ur 5.7 ~ my case: ‘10 Crew, 150k, but 2wd + 4.6 sucking thru a K&N drop in filter (+ bed topper), 1 size up from stock LTs on alloys / tow pkg (rear end 4:10 I think?) Brings me to about 21.5 Hwy (mixed, just like your test run). My stock exhaust always kinda drones - any sure bets out there on a possible classic lower tone exhaust that won’t sound too ‘over the top’ on heavy acceleration ?? 🤔

seems to me that most vehicles get about 10% better fuel economy when not using E-10. that's from years of writing down mileage, gallons at fill ups. for me, that suggests that unless E-10 is not MORE than 10% less than non-ETOH fuels, it's more economical to run the E-10. Now, my 2018 tundra, SR5 crewcab with cooper at3's on it regularly runs in the 16-17 mpg range when on long interstate cruises at that 70-80mph range. properly inflated tires makes a difference of a little over 1mpg from some quick observations as well.

I have the same truck right now I literally have it in my driveway

I have the exact same truck mine is the trd version

I was getting 12-13 in my '07 (same config as yours), changed the leaking radiator and new coolant brought it up to ~17?!?!

Got 15 in the 22 tundra, had many issues! Got rid of it!

Its your cover 😊

I have a 2016 lifted 7” on 35”s 4.6 liter v-8 says I average 12 mpg . Might as well grab a 5.7 instead 🤬

love our videos. I have a question . Recently Ive been offered a, 2015 Toyota Tundra TRD - SR5 _ with the 5.7L 8-Cylinder Gas Engine . Miles are under 80 thousand . Its absolutely imaculate. The only thing is its 2WD and not the 4WD , but I prefer the 2WD since it hasnt snowed where I live in 8 years. I can get the truck for under $20 thousand. I would love your advice. I really like this Toyota engine and its a crew cab. Thx Buddy.

I wonder how much better gas mileage the RWD gets? Would the higher octane gasoline get better gas mileage?

My 2012 gets a steady 16

Do u have factory intake?

I had a 2015 crew cab 4x4 Had a 2” lift leveling kit and 35” Nitto hybrid Terra on it. Love it but every darn time I went to fill it up. It was always 11.3 Mpg best I ever saw it get was on interstate 15..5 Mpg Only had it two years worst gas mpg of anything I’ve ever owned

Lot of people mad for some reason when you bring up mpgs on a tundra and i don’t know why. It’s kind of like you’re questioning their masculinity or something. That’s the knee jerk reaction to it. If you monitor mpgs itll tell you the health of the engine. That’s how I’ve caught faulty plugs 2 times. Its a health check on the engine nothing more nothing less lol. Tires make a huge difference in mpg. I gave Michelin Defender LTX M/S and get good mpgs because of their low roll resistance. A/T and offroad tires are heavier and will give worse mpgs.

Better mpg compared to my 2002 ford f350 v10

Just got a 2015 tundra. Yeah 11.3 is what I’m getting. Of course it’s snowing up here in Alaska. I’m just trying to figure out how to get my damn tire pressure light to go off. I’m within limits.

I Average @ 12 MPG with stock sized tiers

I got 17.2 miles per gallon. On my 5.7, it's gonna happen.

I get 11.3 mpg average in town

2018 20mpg hwy... when towing 13.5mpg hwy

Nobody get a Tundra for just Gas mileage, we get it for the big mean nasty truckiness of it, the 5.7, bulky body, V8 growl, reliability and tow haul mode, ethanol clogs injectors, or at least slows them up

12.5 with an exhaust leak and a healthy foot haha. A DIY exhaust install is just as stressfull as paying the labor do it. F you ol' reliable tundra haha

I’m confused what type of mpgs are you expecting from a heavy a$$ truck? I mean if you want 20 plus mpgs buy a sedan.

17 on the highway is accurate.

tundra 4.6 5.7

30 seconds in and commenting my guess on his highway mileage 15.5 miles to the gallon.

I always say it, what you save on gas from one of the "big 3" trucks, save it for the mechanic. OR go buy a tundra and just buy gas.

I get 19 on fwy

Hum in co the guy get 12 mpg

I would much rather pay more at the pump with less times in the shop for repairs. Ex: Ford, GM..

I get about 15mpg

You only have 170K miles, mileage should get better when the Tundra gets broken in. 😊

Those tundra trucks are way more reliable than those f150 Silverado and ram trucks

I've had three now I have never gotten over 12 mpg
