victorg009..........It's obvious you don't own a GMC Acadia because an elderly person driving in the right lane doing 50mph will NEVER get 20mpg!!!!!!!!!
I personally drove my wife's Acadia Denali for 230miles straight and suffered doing 60mph just to prove a point and I was able to get 16.2mpg.......BIG DEAL! I own a 2010 Dodge Ram 1500 w/HEMI, 390HP and driving it as I would everyday which is not like an elderly I am still getting 15.4mpg around town and 22mpg on the highway.I purchased this truck without worrying about fuel consumption and didn't care and it still exceeded my expectations.
I was always told that the GMC are the better of the GM lineup in trucks...YEAH WELL THAT'S BS!! Thank god I leased this car BUT unfortunately I'm stuck with this junk until August 2014.
I will NEVER NEVER NEVER consider a GMC or recommend to anybody. The company is full of IT and I'm surpirsed GM can allow this.

hsalinas: I do own 2010 Acadia SLE AWD, and it gets 19MPG on roundtrip from Bay Area to Tahoe which includes climb to 7000' mountain. On flat freeway it can get 20+ MPG, but there are no flat freeways in Bay Area.
Acadia weights 3 tons and it takes lots of gas to accelerate it after stopping in city driving. The only way to improve MPG is to accelerate slower.
Another factor is Acadia transmission is programmed to downshift immediately when you touch gas pedal even slightly, and when downshifted it accelerates much faster and therefore consumes more gas. This sporty transmission mode is similar to Overdrive OFF in our old 4-cyl Camry, and with Overdrive OFF even Camry burns gas like Acadia.
I do like our Acadia when we go on family trips. I hate it when filling at gas station or every time I look on gas level gauge.

I have had my FWD Acadia for 3 months now and have driven approx 2500 miles.
I have been most unhappy with the gas mileage I have been getting (less than 16mpg in general driving, much of it highway).
I mentioned this to the Service advisor at my dealership and was told "That's all you're going to get"
I quoted the sticker mileage of 24 Hwy and was told that was a very optimistic number under perfect conditions.
BS! The tests behind those numbers were changed a few years ago to be more realistic!.
I took my first 400 mile purely highway trip last weekend and drove 70mph. I got 21.8mpgs.
Better than some people are reporting but still not what I was hoping for.
To put things in perspective here - that is 2mpg LESS than I used to get driving a 1995 Buick Roadmaster station wagon with a 5.7L V8. With 16 years of "Progress" I expected the Acadia to do better.
I also own a 2500HD Duramax Crew-cab pickup that I use to tow a fifth wheel. I have driven the SAME 400 mile trip with my truck (unloaded) and got 20mpg.
Not good enough GM.
But I leased it so am stuck for another 3 years. I will NOT lease another one.

I apologize for the mileage you are getting. I would encourage you to take your vehicle into your local GM dealership to be looked at. Please keep me posted on any information.

Thank you for responding.
I HAVE been back to the dealer. Their response to 18mpg (mostly highway) was "that's all you're going to get" and when asked about the 24MPG Highway rating was told "That's very optimistic under perfect conditions"
They then told me to let the engine rev wide open now and again and wait until I had a "few thousand" miles on the car before being critical.
Let's put things in perspective! I'm a GM retiree Manager who used to drive a company vehicle. I ALWAYS exceeded the published (and optimistic pre-2008) mileage ratings from day1 for EVERY car I drove.
Look at my previous post for the mileage I was getting from a 1995 Buick Roadmaster wagon and a 2005 2500HD pickup for example.
For vehicles slightly closer in comparison I regularly got 16/27mpg out of the plastic U-Vans (Lumina APV and Pontiac Transport with a 3800 push-rod V6) and comparable numbers out of the later U-Vans (Venture and Montana) with a pushrod 3.4V6.
Granted the Acadia is a bigger vehicle, but with all the technical advances and a six-speed transmission I was optimistic that I would get AT LEAST the posted (and supposedly more realistic) 24mpg.
My last tank (filled yesterday) with a mix of highway (75%) and major road (25%) driving, I returned 15.1mpg!
My old Buick ALWAYS gave me 20mpg in identical driving. In fact I used the mileage instead of the fuel gauge to judge when to fill up, it was THAT consistent.
As I said before, 16 years of technological advances do not seem have found their way into this Acadia.
And I'm obviously wasting my time at the dealer!
Like I said - NOT impressed at all!

The mileage I quoted for the Lumina/Transport/Venture/Montana should have been 26/27, not the 16/27 I mis-typed!

Hi Caron - thank you for your reply. Is there anything in particular that we should tell the service department to check? Is it your opinion that we should get a higher mileage?

Hi rerman, just wonder if your service dept was able to identify the problem with your low mileage?

I apologize I do not have a recommendation. They will know where to look and what to look at.

#139 of 258 2011 GMC Acadia FWD- Poor Gas Mileage
Oct 14, 2011 (3:11 pm)
I have had my Acadia for 5 months now and I am averaging about 13.5 MPG. Obviously this is no where near the range on the sticker which is 17/24. I would have never even considered this vehicle had I known that the gas mileage would be nowhere near the range on the sticker, but since this vehicle got great reviews for fuel economy I thought it would be a good vehicle for my family. I was completely wrong because I had no idea what it was going to cost me to fill it up! When I got the vehicle the salesman said to use Top Tier Gas and that they had a lot of people complaining about fuel economy, but he led me to believe that if I put "good" gas in that the mileage would be better, of course as I learned, Top Tier Gas does nothing for fuel economy. I do not have a heavy foot and my tires are properly inflated, recent oil change, etc. I have tried it all and nothing has helped my fuel economy. I took it in to the dealer two weeks ago to get other work done and also inquired about fuel economy at that time which they basically just ignored. I am very frustrated and made a second appointment, but this time just to have the fuel economy looked at. Has anyone had any luck getting the dealership to do anything about this problem???
