I thought that it was funny when I went to Key Largo in January I averaged 18 mpg driving up and down that one highway that goes everywhere and ow I'm back in Pittsburgh where I always get 12.5mpg driving the same way.

Hills are a killer.

My daily commute takes me about 30min each way to go 20 miles on secondary roads with about 20-25 stop lights to get to work. Reading is 15.0mpg and has hovered around 14.9-15 since last April when i picked it up. Seems like other Toyota SUVs, LC that i;ve owned are running around that mpg give or take 1 to 2. miles. Granted they have lasted 200k miles with out any huge needed service besides timing belt/water pump change. I'd take that vs being in the shop a few times a year for other issues that ive seen with other makes out there.

My daily driving is a mix of interstate and local roads. Average around 14.something to 15, tops.

I took a drive from St. Petersburg to Orlando and topped out at 19.5 mpg. Granted, the only thing in the truck was me and a passenger.

Considering the 5.7L V8 goodness at my command, I don't think that's horrible mileage. Nothing to brag about, sure. But, I prefer to own a truck that starts when you turn the key.

I think its unfair to compare and so quickly claim the Tundra is a gas guzzler compared to its competitors.

Compare power output for one thing and lack of high octane fuel requirement. Those getting 18-22 are not getting the same power output we have, and those make a little more power, require high octane fuel and dont get any better MPG then we do.

And try to find 1/2 ton truck owners not running the ECO wimp diesel getting over 18-19 consistently.

From what I find, our 5.7's are getting respectable REAL WORLD MPG compared to all the others.

If you really must nit-pick...averages of the masses found on Fuelly for example *might* be 1-2 higher. Is that a big deal for a truck? I think not.

I average 14.5 hand calculated in 50% highway 50% stoplight driving. Thats with a heavy foot and a supercharger.

If I wanted gas mileage I would buy a Prius. I wanted a truck so I bought a Tundra.

I certainly wouldn't drive a lesser truck for 1-2 mpg improvement.

Seriously, if people are that concerned with mileage, why get a truck? I am concerned with MPG's, but I have a Prius for that, and a Tundra for when I don't care about MPG's.

Pointless thread......

You may pay a few more dollars in fuel costs but you save a ton on repairs and depreciation. A great deal IMO

 

[Luke the Dog]

Always read the fine print when you read car ads too, often there will be a little symbol that directs you to the tiny font that says the advertised mpg is based on the lightest, most fuel-efficient model. The big 3 are always guilty of this...

Also, I'd much rather be paying for more fuel than paying for parts and labor!

 

[Mcchase]

I think part of it also has to do with the front air dam ford/chevy hang off the front bumper. It reduces ground clearance up front by several inches. I know when my f250 busted its front air dam I lost 1-2 highway mpg. My suburban drags when I pull up too far on parking lot curbs.

--- THREAD RESET ---

I like all the input. Great points made, especially the hills. When you take a nationwide average you don't take into account the environmental variables depending where each truck drives.

But back to the purpose of the thread... There are endless threads on what actual MPGs people get. On this thread I was hoping to focus on the WHY? Like what mechanical issues are the biggest factor? And would Tundra owners be happy if Toyota added those factors that increase mpg to same levels as comparable trucks?

Disclaimer: None of us are willing to change vehicles for better mpg we all knew what we got into willingly. Tundras are still comparable to others but we all know we're lower even if just by margin. And yes, Tundras beat other vehicles in countless categories so they're still a better choice even with even lower MPGs.

Ok, thread back on course. Mechanics and super smart aficionados please chime in to what mechanical design factors affect MPGs most directly. Thanks.

Yeah...im just about ready to close this thread.

2017 Lexus LX 570, same 5.7 weights 6k gets same MPG with the 8 speed transmission (13city, 18hw, 15combine).

You ask me it's the steep gears, alot of the domestic are running 3.08, 3.23s all for highway mgp

Damn! Well that was unexpected. People communicating and a member asking a valid question to better understand his truck, a question that Google can't seem to answer so I brought it here with the expectation that an open forum for sharing knowledge would be able, willing, and interested in answering. And the mods wanna close it cause two people wasted their time reading another mpg whining thread and then whined about wasting their time.

Point is... I Care! That's why I asked. And nobody is whining about low MPGs. I didn't ask what anybody gets. People are just sharing their minds. Anyway, close it if you want. Shitty, but it's your power. I was just hoping that Google would finally be able to answer this question thanks to this thread and the knowledge in this forum.

Why?

 

[StevenD]

Why?

Because these treads go nowhere. And there are roughly 700 other threads just like this one.

And I get tired of people buying 6000# vehicles and then bitching about mpg.

 

[Idiot406]

It's really simple. Big rear end, big heavy truck, big displacement V8, no shoddy tech like cylinder deactivation.

Damn, I honestly didn't know they ran gears that low. I figured all modern trucks ran close to 3.80 for towing power at least.
