Thanks appreciate the advice. Have been following it though.
the MPG increase you list sounds encouraging - I assume your route has remained the same though in which case it's an impressive increase.
Btw I did get a loaner car from acura. It was exactly the same (2010 tech) and interestingly gave me better mpg on the same exact route (so for e.g. instead of 8 MPG in my mdx, the loaner gave be around 10.5)
that does suggest that either there is may be a natural improvement over time
however one very different thing i noticed about the loaner is that at a stop/light, the minute i take my foot of the gas it would drop rpm and gen slow down quite rapidly (as is normal) and the car would not move forward much. However with my MDX even when I come to a complete stop, the MDX still seems to take a few secs extra in revving down (and in fact keeps moving several feet on a flat road after a dead stop i.e. even if I press the brakes fully and then let go). This seems like a small distance but on a route with lots of stops this can make a big difference
i tried asking the local acura guys whether there was a way to adjust the settings to have a normal/rapid slow down when one takes ones foot of the gas but they didn;t seem to know how to do so or whether this was even possible.
do you/any others notice this with your Acura? (FYI - on a flat surface when I do a deadstop and then let go of the brake my MDX moves forward about 20 + feet easily and only after that comes to a slower crawl)
Btw - there was another boston based post where someone had the exact same problem - the post is no longer there so am wondering what happened? I am still talking to the acura people so would be interesting to compare/coordinate.

Hi - I just wanted to share numbers I have on my '09 MDX (base) - Just purchased a month back when the meter had 17001 had on it.
Total Miles - 17996
Avg Speed - 30MPH
Avg Fuel A - 28.0 MPG
Avg Fuel B - 20.8 MPG
I drive about 5 days (work) in city and 2 days on highways. These readings are right after my couple hours drive (120 Miles)
I feel these are good numbers, what do you guys think.

Has anyone tried Fuel Doctor FD-47. I saw this in Best Buy last week. Packaging says works well with vehicle 2 or more years older and improve the mileage by 15 to 25 % ?
Just interested to know if any one Acura MDX 2008 or older owner have tried it and if so, what he thinks about it. Neither I am favouring it or otherwise, just curious to know.
#204 of 243 2010-2011 Acura MDX Gas Mileage
Feb 01, 2011 (5:52 pm)
I have a 2011 MDX Tech that now has 425 miles on it. Using premium grade gasoline, I am only getting 13.5 mpg city and 18 mpg highway. The dealership tells me that I must put a few thousand miles on the car before I can begin to see the mileage approach what the sticker says. I would be very interested in hearing what I should realistically expect in terms of gas mileage. Do you agree with the dealer's statement? What is your experience with the 2010 or 2011 MDX?

How one drives and at what speed has a great deal with your mpg. I have an 08 RL and I get in the city about 20-21 mpg. I do not race it but just try to stay steady speed. (I'll probably buy an MDX in the fall so I follow this board.)
Now many of you may queston what I say now, as i did at first. On the highway at 75-80 mph, (yes I speed) our trip down to the Mojave Desert and later up to Yellowstone from the SF Bay Area Ca. i averaged 29-31 miles per gallon with cruise control on at a steady 80 mph.
I believe the MDX is a bit smaller than my RL, and little less weight ergo, after break in the mdx should do better than my old 08 RL.
I am not trying to start something but I do see a divergence in results on this board and on the RL board. I hope ALL of us get excellent milleage and enjoy their vehicles for a long time.
Good luck to all and stay safe.

This is my third MDX. I first owned a 2004, then 2007, and now just purchased a 2011 in December end of last year! Gas Mileage sucked on the 2004 and I swore Id never buy another MDX, however, I needed an SUV to tow my horse trailer and was impressed with the 2007 , 5000 pound towing capacity and style. It turned out I loved my 2007 MDX and the mileage per gallon averaged 17 city and up to 23 hwy with my ac always on. It appeared they had fixed the mileage issue with the 2007 model to be efficient!
So when it came time to trade up, I assumed Acura would have implemented the '07 mileage fix into the '11 MDX models, but I was wrong! I too have been extremely disappointed with the low miles per gallon on the 2011 Acura MDX. Like you, I first only averaged 13 city and 15 highway. I'm now at 4000 miles and am up to 15 city and 18.1 highway. I'm still holding my breath for the 23 mpg highway like I had in my '07 model! Try resetting your speedometer after filling your tank each time. I too hope things continue to improve with the rising of gas prices, otherwise, as much as I love the new MDX model, this will have been a financial mistake!

Thanks for taking the time to reply. I only have 1,000 miles on the car now so I'm hoping to see some improvement as I add more miles. We'll see.....

Gas mileage has dropped from 18 mpg to 12 mpg over the last 2 years (70K through 95K miles). Both dealer and independent Honda/Acura shop say there is nothing wrong with the car, but ahve been willing to try to fix it by replacing fuel filters, plugs, throttle body, and intake manifold - to no avail. At one point we thought it might be transmission/differentials but the dealer eventually concluded they damaged a solenoid when replacing motor mounts. Car runs fine otherwise - no loss of power or anything. Has anyone had similar degradation in fuel economy and found a fix to the problem?
