Theres a 35 speed limit stretch on the way to a grocery store. The past few times I reset the trip comp. as soon as the mdx reached 40mph. just for the heck of it. It consistently shows 33-35 mpg. Can this be right ?
No a/c, had windows down. |

No possible way unless it was a very short didtance like half a mile or less with no lights.

No way! Unless you are going downhill without stepping on the gas pedal. |

Point in time checks are not very accurate at there are too many variables that can effect the readout. Most cars get optimal gas mileage at about 50-55 mph (all things being equal). So it would be surprising to get that good gas mileage on the MDX under any conditions going 35mhp. It may likely be a slight decline hill area which can have a significant impact on mileage.
Technically you can get the MDX to read out 50mpg + if your going down a hill. I actually got my Grand Cherokee to read out 99mpg going down a hill .
The best I've ever really got was on the MDX was 28mpg, and that was over a 100mile stretch of highway keeping it very steady at 55mph. 55 seems awfully slow on the highway these days, it was a test of patience. |

any car will show 99.9 mpg if you reset the trip computer (mpg meter) and then coast long enough at sufficient speed.
For example take your foot off the gas when going downhill at say 40-50mpg then hit reset and let it roll as long as you can.
the opposite of that is starting off from a stop. Press reset and hit it. Don't be surprised to see 1.5 or 2mpg before it levels off around 5mpg. Should be quite a humbling learning experience for those jack starters and high rev starters. |

no downhill, no coasting, no cruise but constant on the gas pedal. 1 mile flat stretch with no lights.
Bottom line, point in time checks are not accurate over short distances.
If I happen to be on a longer 35 mph stretch I will get the data and post it. (not crazy to try this late night on a highway)
Appreciate all your responses. |

I averaged a little over 29 MPG with my '02 MDX on a 45-mile trip (back around Memorial Day). The asterisks: it was all highway driving; there were NO stoplights (or stop signs); and there were very few hills.
I think the main thing that kills fuel economy is stopping and starting; I think if you can get up to highway speed and then hold it steady at 55 or so, you can get amazing gas mileage with almost any car (well, maybe not a Ferrari or Hummer).
Another thing to consider is the air filter. I've always put K&N air filters in my cars and have had great results. Case in point: a couple of months ago, I talked my girlfriend into putting one into her '06 TSX. Her average MPG jumped from 28.3 to 31-32 almost instantly.
Just thought I'd share. |
