You are in the Acura MDX
What is this discussion about?

We do not own a 2007 MDX (neither do you I assume), but I'll nontheless take on your cynicism that anyone can achieve better than the highway EPA estimate on the 2007 MDX when cruising at highway speeds. I have kept detailed mileage logs for all of my vehicles. I also travel regularly 370 miles each way to our second home. Virtually all highway, including 150 miles of PA Turnpike which includes some significant hills and grades. I average 65-70 mph with 2-3 rest, lunch or bathroom stops. Here are actual results:
1995 Nissan Maxima SE 5-speed: EPA 22-27; actual MPG: 27.8 to 30.1 estimated average 28.5.
2002 Honda S2000: EPA 20-26; actual: 28.8 to 32.5. Estimated average 31. (28.8 was with the top down, all others 30+).
2004 Acura TL 6-speed: EPA 20-29; actual 28.8 to 32.1. Estimated average 30.5.
2005 MDX: EPA 17-23; actual 22.5 to 26.4. Estimated average 24.5.
2005 Porsche 911S Cab: EPA 18-25; actual 25.5 to 28.1. Estimated average 26.5.
In all of the above cases, my actual highway fuel efficiency for straight highway "cruising" is higher than the EPA estimate. And this is not babying the car at 55 mph downhill downwind, but similar 370 mile trips at 65+ mph, with grades.
I think your cynicism of inkyofok's claim to average 25 mpg at 65 mph cruise in the 2007 MDX is misplaced. The fact that the 2007 V6 has a bit more horsepower than the previous model is insignificant to highway cruising at 65 mph. It's no heavier and perhaps a bit more aerodynamic and the added power actually helps maintain speed on grades. As a matter of fact, we only averaged 19 mpg on our routine trip with our old 1996 Isuzu Trooper 5-speed with 190 horsepower. It had to be downshifted constantly to handle the Pa Trunpike grades.
Tidester: Hopefully this meets your request for "real world" data. But I think your indirect defense of hpowders was also a bit misplaced. I was polite in my response, but someone that states "I don't believe you" as much to say "You're lying" is apt to get a punch in the forehead from me in person.

But I think your indirect defense of ...
That was neither my point nor my intent. Even your top MDX mileage (26.5 mpg) is 5 mpg less than the claim made by the original poster (31-33 mpg average). It would certainly be interesting to learn how that was achieved without being enticed to go elsewhere for the information.
I have no problem with the data. I just want to know how it was done.

When someone claims 31-33 mpg average in the "real world" for a vehicle as big and heavy as the MDX, I have the right to challenge his credibility.
The host asked him to provide his methodology. So far, nothing but silence in response.

I have an 06 Touring, and since the wife and I work within 2 miles of each other, we 'share' the car a lot of times.
I notice on the highway, she has this odd habit of constantly adjusting her pedal pressure.
On-off-on-off-slightly back on-off-on-... drives me bezerk!!! Ugh, I hate what she drives LOL
Anyway, when I have the car, I'm in the area of 23.8 MPG average.
When she drives, it's an average of 17.
I drive more aggressively than she does, but I don't fiddle with the pedal as she does.
Something as little as that makes a big difference.
I have never gotten the MDX above 25 MPG average for any real amount of time.
Maybe a half mile down hill, but that's about it.

And, may I remind you, you started this off with:
"The only way you can maybe get 28 mpg with the 2007 MDX is if you remove all the seats, have a fraction of one gallon of gas in the tank, fill the tires with helium and have a category 2 hurricane following from behind.
In other words, I don't believe you."
The poster you challenged qualified his MPG experience as 28 mpg at a 55 mph steady cruise and 25 mpg at a 65 mpg steady cruise.
Although I would fall asleep or be run over from behind trying to test a 55 mph cruise on our MDX, the 25 mpg at 65 mph is completely consistent with our experience, using cruise control for long highway trips.

LOL, My mother-in-law must be from the same gene pool as your wife. After the second automatic transmission replacement on their Saab, the mechanic went out with her for a drive, called my father-in-law and told him to either buy a manual transmission (w/o a torque converter) or divorce her. Apparantly, doing the herky jerky on the gas pedal is not only bad for fuel efficiency, it's one of the worst things you can do to an automatic transmission.

Great, as if I didn't have enough worries with the impending torque converter issues on the MDX as it is.

Because posts get buried here at Edmunds, you cannot do much with a 15 page post and have to post it again and again and again over the years. When I link Edmunds from CleanMPG, it can be found quite easily … I asked Sylvia to build a Mileage DBase years ago and of course none can be found
As for the details, Google my name and you will find all kinds of details from tens of other sites on how you get 30 + in an MDX, 60 + in an Accord, 120 + in a Prius II and 195 + in an Insight ... Those are long distance segment peaks however.

The "MPG-Real World Numbers" discussions constitute a database.

The question was how do you achieve the numbers you claim? 15 pages and dozens of sites sounds way too complicated but a "Reader's Digest" version here will do nicely.
