i wish that were true but my husband tends to speed more in our 05 hyundai elantra GT 5 speed than he does in our 06 acura tsx 6 speed. we also get good gas mileage in our elantra-average 33.5 mpg. it has just over 60,000 miles-

I picked my new 08 6spd TSX up about a month it ago. It was my third car (till my Civic was stolen last weekend) so I only filled it up twice. The first tank was about 27mpg, and most of the miles were highway (bought the car in VA, drove it back to NJ). My second tank was 22mpg, and according to the MID this one's not going to be much better...
 
I don't get it. I don't floor it, and always shift at around 3k rpm's..75% of my driving is highway, 25% city.

Give it a few more tankfuls to even out fill variations. However, don't expect stellar MPG in NJ or anywhere else in the Northeast - ethanol blended gas used in these areas will drop your MPG by 5-15%.

Had mine for 1 month. Best mileage (highway) was 34. Mixed driving has been around 30. Using mid-grade without any issues...

My new 2009 TSX automatic trans, mixed drive highway and local is about 27, it should be better because my wife do not have a light foot. we live in Dallas, it is flat, so there is no up hill or down hill. But there is some traffic jam, so I think this number is pretty good.

Just filled up my lightly used TSX for the first time, 24 mpg here in Denver. Using midgrade.

Trip computer is way off my manually calculated MPG by kjnorman

I have an 08 TSX that has now done about 4600 miles. With every gas receipt I have been recording mileage and gas used. I have noticed two things with the car:
 
1) The trip miles - reset at each fill - does not total the total mileage accumulated. It is typically 1 to 2 miles lower on each fill than the total mileage being accumulated on the car. Initially I thought this was just me not resetting the mileage in time, but since I have been aware of it, I have deduced that it is the trip computer than can not add up, and not me.
 
2) The average mileage per gallon that is calculated on the trip computer is over calculated. Typically it reads 2 to 3 MPG over and above what I am calculating. Now I understand that by filling on different pumps that the gas used may be sightly under or over read, but it usually balances out over a few fills. But I am not seeing this. Take for instance, my last few fills. Last one was recorded at 29.9MPG by the car, 27.7MPG by me. The one previous to that was 29.8MPG by the car, 27.5 by me, and the one prior to that was about 27-28MPG by the car and 25.9 by me. I don't remember this last one exactly but it was significantly off and was the point that sparked my interest in the accuracy of the trip computer. It seems to be consistently off.
 
I am now adjusting my spreadsheet that I use to calculate my gas mileage to track the trip computer totals as well, just to see how bad the trip computer is.
 
Has anyone else been seeing this?

I found this to be true in my 07 TL. Most of the time the trip computer reads 8-10% too high. This past weekend I had an 09 TSX while my TL was in the shop and used 1/2 a tank and compared the real mileage to the indicated mileage and it too read about 10% too high. No one at any dealer or at Acura has been able to explain why their trip computers all seem to display number that are consistently 5-10% too high.

We have found the trip computer to be the same or very close (less than 1%) on our 06 tsx when we compare it to our manual calculations for MPG.
