Toyota Sequoia gas mileage

Can anyone out there please advise me as to the expected gas mileage with a 5.7 Sequoia. I was getting 14 mpg towing but it suddenly went to 10! I think it may not be going into 6 gear. Any thoughts? I can't find a rpm/road speed chart or graph. Thanks!

We have a 2008 Tundra with the same engine and transmission, and we tow a 19-foot Bambi; so I would guess that your mileage would be similar.

On the flats, we get 16.5 mpg at 55 mph; 13.5 mpg at 60 mph; 12.0 at 65 mph and about 10.5 mpg at 75 mph (only took one trip at this speed).

We cruise at 55-60 mph most of the time, even if the speed limit is much higher (Arizona Interstate speed limits are 75 mph in most areas).

Note: I do NOT use tow/haul mode.

You might find that you get better economy in 5th gear. If you don't have some sort of MPG monitoring, I'd suggest getting some.

30% of mpg changes are made by adjusting the nut behind the wheel.

If that's not the problem, check tire pressure, air filters, fuel filters, wheel alignment, etc.

There's also 25 different ways I've seen people come up with how they figure out their MPG. 24 of them produce inaccurate results.

Weather, driving conditions, hills, road surface, wind, rain, speed, aerodynamic changes, etc. all have an affect on MPG.

Last week, we were returning from Tucson to Phoenix (very flat); and I was cruising at 60 mph with our Bambi in tow. When I came upon a semi with a wide load going about 57 mph, I slowed behind it; and our Tundra shifted to a higher gear (apparently from 5th to 6th). In addition, the computer-indicated mpg also changed from 16 to 18.5 mpg.

Evidently, the wind resistance from that extra 3 mph prevented the transmission from shifting to 6th gear -- Another reason for slightly lower cruising speeds (if fuel economy is important to you).

Drafting wide load semis will surly increase your economy! You need to get within 1 foot for the best results.

My truck will cruise at 60 in 5th or 6th. Without a load it's about 10% better in 6th, and with a load it's about 10% better in 5th. That's only looking at the fuel consumption in mm^3 (the way my tuner displays it). I get about 16mpg with the trailer, and 23mpg without on B100 at highway speeds 55-60mph.

There is a new Dodge 1500 supposedly coming out this fall with a 3.0L Italian made V6 diesel. I've heard rumors of a 1/2 ton diesel for about 10yrs, but this time, Dodge officially announced it Feb 15th? or something. If it works out, hopefully it will be a success, and will make Toyota bring the diesel Tundra to the US.

I should have noted that this mpg increase was NOT due to drafting; we were in heavy traffic with about a football field length of separation between our Tundra and the semi to allow passing vehicles to pull in. We do not draft, nor tailgate.

As an added note, my wife was following in our 2002 Prius. It normally gets around 42-44 mpg at 75 mph. However, at 57 mph, it was getting 56.5 mpg. (She wasn't tailgating me, either).

That's even more interesting.

Sorry if I was insinuating you were tailgating. Even following at 6 car lengths back I think you'd get a little help from the draft, but not at 100yds.

Agreed on many levels, slowing down will help economy.

Mythbusters proved this is not true, best results were at 10' back, they said that to maintain distance closer then 10' you had to play with the throttle too much, which wastes fuel.

We have a 2011 23FB and a 2011 Sequoia with the 4.7L. I believe the mileage difference between the 4.7 and the 5.7 was only 1mpg in the city? Anyway, I usually average 12-13 mpg when towing our AS

So many factors at stake here. I generally get around 12-13 MPG with my Infinity QX56. IF I am towing through the mountains, I'll know it on the "distance to empty" display. Anytime I see the tach surging as that huge V8 downshifts a gear, I can just about hear the sucking sound of the fuel pump going into warp drive....I've gotten to the stage now of just saying, "it is what it is," and letting it go...
