MPG for'09 Highlannder 4 cyl by warm1

Mixed MPG is 25. car has almost 9K miles on it. Earlier this year I put about 5K miles on it on a drive from one end of the Louisiana Purchase to the other(Houston to Oregon), and averaged 30 MPG and 75mph while on the highway.
I really wanted the GMC Acadia, but Detroit didn't produce a large SUV(90 cubic feet or more) with a reasonable fuel economy at the time.

HELP! I can't get past 16.9 mpg! by johnstp

I recently purchased a 2006 Highlander Limited V6 4X4 with the third-row seat. The vehicle has 52,000 miles on it. Bought it Certified Pre-Owned.
 
The mpg is awful and seems to be way out of line with what I'm reading here. I live in the country, so most of my driving is constant, highway speed. Very little stop and go. Very little idling.
 
I'm doing the actual math, rather than relying on the digital readout. So far, I've put about 2,300 miles on the car and my best tank yielded 16.9 mpg. Basically, I'm hovering between 16 and 17 mpg.
 
Am I doing something wrong? Any suggestions I can take to the dealer?
 
HELP!!!

The EPA rating is 17/23. How fast do you go on the highway?

Getting about 16 mpg around town and wondering if my air/fuel sensor could be going bad and causing it to run rich. I also have a smell of gas in the garage after driving. No leaks that I can see. Also have the dreaded CEL come on after an inspection due to a hose off the air cleaner. Got the P1150 code but cleared the code, cleaned the front sensor contacts at the connector and hasn't come back on. But wondering if sensor could be going bad.
Any thoughts from the collective brain trust?
Thanks!

Wow! 27 hwy, you must be a very good driver and rarely use the brake.
 
Now I have 1000 miles on my 09, V6 base 4X4. The average is 20/21 for mixed city/hwy, I used "Snow mode" in the 3rd tank but didn't get any better than regular driving, there is somebody said "Snow mode" may improve mileage a lot but I am wondering if this would hurt engine in the long term.

Terrible Mileage! by kkd1

I bought my 2009 Highlander a couple months ago- not even 1000 miles on it yet. It started out getting 18 mpg in town, then 15, then 13. Today it used 1/4 tank of gas in 20 miles. There has to be something wrong, but what?

My minivan has averaged 21 mpg lifetime over the last nine years. But the first ten tanks varied between 11 and 20mpg. It really didn't settle in with consistent mpg until 3,000 miles, and even then it kept creeping up over the years. It didn't hit the EPA rating until 7,000 miles.
 
I'd try to fill the Highlander consistently (i.e., no partial tanks, fill it just to the first click, and even use the same pump every time if you can), and keep good paper records for the next 2,000 miles. Then you'd have reason to worry that something is wrong if the mileage doesn't approach the EPA estimates.
 
In the meantime, there's not much you can do about "winter" gas, but these tips may help.

4 Cyl. Mileage by derkommissar73

Just wanted to post that with about 6k on our 2009 4 cyl. Highlander, we're averaging right at 23 MPG. We do a mix of highway and city driving, but no long mostly highway trips yet. Overall, we've satisfied with the mileage and power. We're getting about the same mileage as we got with the 2003 4wd CR-V we replaced, but with a lot more space and comfort.
