So I took my Tundra for its first long trip since I have owned it. Its an '06 Double Cab 2wd 45,000 miles and completely stock except the 265-75-16 tires. I run mobil 1 oil and filter and I just replaced the air filter. On a 500 mile round trip at speeds of 70-75 on a windy day with gusts up to 40mph, my Tundra averaged 19.87 miles to the gallon. The truck was fairly empty just a couple hundred pounds of stuff in the bed and 2 people in the cab. After seeing these results it makes me even happier that I chose to buy my Tundra :D

After reading a bunch of posts about people who get poor mileage I thought that I would just share my experience with everyone

I believe you've set some sort of record. In 117,500 miles the only time I've seen close to 20mpg is on a cool day, no A/C and running for most of the tank at about 60mph. Get closer to the speeds you talk about and I might get close to 18...but more likely about 17.5. 2005 D/C with OEM size 265/65-17's.

I check every tank...it's an old habit.

On my first fill to fill I averaged 20.1 MPG

on my second I averaged just under 14 which half or which got burnt towing a 1500lb trailer 70 to 75mph with 5 passengers in the cab.

putting my average to date at 16.68

Ill update this post if it stays close to the top.

The above numbers reflect pure dino based fuel. No corn based rotgut garbage in the mix

I had the A/C on too, I think I might have been able to get a higher mpg if there wasn't such a strong wind

It's only a matter of time before the mileage police start to give their unwanted .02 about how you're lying and off your rocker. I believe the numbers you posted because I have gotten 20+ in my 08 CM 5.7

aren't those the guys I see driving 80mph on the interstate when they're not flogging it at 1/2 throttle round town so everyone can hear their CAI & exhaust in a truck rolling on wide oversized tires and black wheels that weigh 70lbs each.

HAHA!! AMEN! I get 20mpg if i stay around 55-60mph and I have 285/75/16 tires, k&N intake, jba headers, dual flowmasters, and jet mass flow sensor. But at 65-75 I get around 18. If you drive like a normal humen being you can get that!

Except for the CAI, that is me. For the record, my wheels/tires weigh in at 80lbs each, and don't forget the matching spare. I likely get 15MPG, most of it is city driving. Since installing headers I notice my gas seems to last about a day longer between fill ups. That is, when I am not flooring it! :D

Until gas goes to $5 per gallon, I'll continue to drive my truck with enthusiasm. Good job on the mileage though, it is nice to hear what Tundra's are capable of.:first:

See what I mean Indigo2k? As soon as you post "unrealistic" mileage numbers, you get nothing but smarta$$ replies from all the guys who decided to lift their trucks and add lots of extra weight with their cool looking off road tires. Since they will never see 18+mpg, anything north of that must be lies and B.S. that we decided to spread around on the internet because we have nothing better to do.

I dont see it as Tundrunk argueing with you, he says he's one of "them" that gets lower gas milage ....BECAUSE he drives the way that he does, and he makes NO issue about your milage...........why are you so touchy?.......I have gotten from 15 something to 20 and some tenths.......MOST of it is the way it is driven and set up......and Tundrunk makes no excuses .......just the way it is. As always my .02

Sounds just about right. When I do escorting I have my OVERSIZE LOAD Sign up (which is a big sail :D). My truck weighs in at 5400 lbs because of the equipmnet I have. Big loads move slowly and I get around 18-19 mpg. When I headed home I do around 70-75 mph and get 15-16 mpg. Not bad considering having 180K miles on it. :amen:

I don't see anyone's numbers here unlreastic... If he said he got 25 MPG I would wonder... Trucks are rated for 14 - 19.. 20 isn't out of the ballpark... I've gotten very close to 20 and that was when there was moderate traffic and I could only drive 55-60 MPH. My normal driving habbits put me in the 14 range, but that is mostly because of city driving. Ohh and I am all stock.

I used to get good mileage in my '05 until they mandated ethanol be added to the gas. I don't see 20 anymore on the highway and my average dropped from 18-19 around town to 16-17. Putting corn whiskey in the gas pump is a waste of both. Anyway, other than that my Tundra still runs well and I still love to drive it. Four and a half years and 49k later I wouldn't trade it for a newer model. I'll get a new vehicle whenever they come out with a truly workable, energy efficient vehicle. Then, I'll save the Tundra for the huntin' woods and trailer towing.

That is exactly where I am at (16-17 mpg) with 10% corn blend. I have 85K on my '05 so it is just broke in. I have another vehicle ('06 Kia, gets 35 mpg) that I can use, but for some reason I always jump in my Tundra. :D

Very nice numbers there. I too got some of he best mileage on a windy day with gusts/ I ran at 75 MPH with the cruise control set and managed 19.96 MPG. I find that weight in the bed (or down force) helps improve mileage.

I find it more accurate when more than one tank is checked. Fill up and miss accurately filling the tank by one gallon and the numbers can swing wildly either way. I'd like to hear how the mileage is over a long period of time.

nice to see another "19er" around here.

i can understand why some folks around here at ts don't get this kind of mileage. i'll go out on a limb and venture it's because they don't care about their milage. and as mentioned earlier in this thread having a lifted truck doesn't lend assistance toward getting 19-20 mpg's either.

it's cool to see other folks that are getting close to 20 mpg's too. i think hwylizard is a stones throw away from getting 20 mpg's on a regular basis.

what was the topography like on your 500 mile trip?

i get 22. 15 in the winter with the tundra and 30 in the summer with the roof back in the civic. So my combined is 22 :)

I have bigger tires on the tundra so 15 city, 17 hwy. It's a nice trade off. Still better than my suv was.

wow, you guys are making me sick. I have an 04 4.7 SR5, 4x4, and the best mpg I have ever gotten since owning the vehicle (bought it used in '08) is 11.5 mpg. Im averging somewhere around 10mpg, and its almost all city driving. I commute a total of 12 miles a day, and I have to refuel about every other week. I have a 24' pontoon boat I take out on some weekends on about a 60 mile interstate drive, and I get about 9mpg. Thats awesome that dont lose much when towing my boat, but geez, this gas milage on my daily commute is getting real old. My buddy just bought an 08 tundra with the v8, and hes getting 19-22mpg.

tires are good, filter is clean, i drive like grandpa, i have ran some fuel system cleaner through it. I NEVER haul squat in my truck, unless you count my gymbag. I have been trying to find a way I can just get up to around the 14mpg mark. That would save me a butt load of money compared to the 10mpg im getting now. is 10-12mpg in my particular model normal?
