#1 of 179 Acura MDX Owners: MPG-Real World Numbers by KarenS HOST May 31, 2005 (6:46 am)
This topic is for MDX owners to report their actual MPG.   "Real World" Fuel Economy vs. EPA Estimates
#2 of 179 MDX mpg by msu79gt82 May 31, 2005 (7:32 am)
We used to own an '01 MDX that we traded for an '04; so we have lots of real-world experience. The MDX takes a LOT of energy to get moving, but does not require a whole lot to keep it going. What this means is that if you do a lot of stop-&-go driving you will experience poor mileage (low 15s at best, maybe worse). Another observation is that our '04 gets about 1 mpg less than the old '01.   Around town (Stop-&-Go): ~ 15.2 mpg Mixed suberb driving: ~ 17-19 mpg Pure Highway (~75 mph): ~ 22 mpg

Trip computer has never been reset. We have 8700 miles and have a grand total average of 17.8 mpg. Around town 30%, highway commute (75-82 mph) 70%. The average has been going up (a tenth at a time) since 8K miles so engine may be entering its true mpg?   Ralph

We have 25K on ours and get 15-16 around town and 23+ on the highway.
#5 of 179 frustrated with 2005 MDX's mpg by mdx4life Jun 06, 2005 (10:28 pm)
I bought my MDX (base) this April and got about 2K miles. It seems like everyone is getting over 20mpg on the highway. So far I got ~15mpg (city 40% and highway 60%). Its initial mpg was about 14mpg. I talked to dealer who told that the car is still new (according to dealer's words "infant stage") and needs to be broken into but dealer did not tell me how long this "break-in" will take. I am suspicious about this break-in period. Does anyone know more about this issue? When a government or independent agency tests car's mpg do they start recording mpg after break-in period? I doubt this but I am keeping the mpg record on my car will contact dealer soon. Is is too much to ask for ~17mpg for a car which they claim gets ~17mpg around city.

Replying to: mdx4life (Jun 06, 2005 10:28 pm) It is well known that the goverment's mpg tests are flawed; almost universally your mileage will be less. Yes the MDX does have a break-in period (varies from 2000-5000 miles); mileage should inprove some, but not dramatically. As I posted above the MDX does not do well in stop-n-go city driving; we average low 15's in predominately city driving. Mixed suburb driving will be anywhere between 17-19. We do get low 20's on highway trips. Also I know from experience that the '04 MDX generally does about 1 mpg less than the '01.
#7 of 179 2003 MDX MPG by silvrfox1 Jun 21, 2005 (4:48 pm)
Getting about 12 mpg in the city, 15 1/2 on the highway. Very bad. Have 11,300 miles on it. Don't believe the dealer when he tells you it will get better. Replies to this message: msu79gt82 (Jun 22, 2005 5:54 am)

Replying to: silvrfox1 (Jun 21, 2005 4:48 pm) Getting about 12 mpg in the city, 15 1/2 on the highway. Very bad. Have 11,300 miles on it. Don't believe the dealer when he tells you it will get better.   I have owned an MDX since March of '01 and am currently driving my second one. We have put over 60,000 miles on our MDXs. I am a longtime contributer to Edmunds Town Hall, having joined in Jan '01 prior to buying our MDX. Additionally I am a top 10 poster over on acuramdx.org and participate on other Acura forums as well.   What's the point? You may not want to believe your dealer that the MDX should get better gas mileage, but you should believe me!! Your mileage figures do NOT match historical evidence from the many thousands who have reported on these various forums. The worst mileage we have ever experienced in predominately stop-n-go city driving is the upper 14s. I assure you that your reported milage is not normal! Check the other forum I mentioned.
#9 of 179 re: bad mileage by sbcooke Jun 24, 2005 (8:38 am)
Are you running premium? Check tire pressure? Is your parking brake stuck? There are some easy things to check. Another could be the gas you are getting, try changing stations, some places offer oxygenated gas (they are supposed to post signs however they are usually small), which is supposed to save on emissions, however you get much worse gas mileage with it and thus use more fuel?? Not sure which is better?
