I just recently purchased a brand new 2007 Accord 4 cyl AT (the "Value Package"). I put about 1000 miles on it and over the several fillups I've had, I'm averaging about 19MPG. Will the gas mileage get better as the car 'breaks in'?

I drive 25 miles to and from work (50 mi/day) and it's about 75% highway type constant speed driving. I am also driving very gingerly during the break in period (no hard starts). The RPMs almost never get over 3K. I'm using mid grade (89 octane) gas.

My previous car (92 Honda Accord LX 4 cyl AT) got considerably better mileage (about 26MPG) and I stomped on that thing like crazy...

PS I did a search for "New Accord (poor, bad, low) MPG but didn't find any posts...

dude your car is brand spanking new go talk to your dealer 1st, then come over to HT and post the results.

I would check the Air Filter.

 

Either your calculation is wrong, or something is wrong with the car. I get over 20mpg easy with an 03 V6, and that's burning 87 octane. Higher octane, by the way, won't help mileage.

 

I found one old post with a somewhat similar problem

It's possible I am not calculating the mileage right. I wanted to write down each full tank I got but I got lazy. I will watch over the next few fillups and recalculate.

I have another question, related to break-in but I think it should go in a seperate post....

Thanks!

 

Yea how do you calculate the miles you get per gallon?

The following is just in case purpose...
When you fill your tank to 'full', reset one of your trip meters. Then on the next fill up, take note of how much gallons you put in at the station to completely fill your tank. Then divide the number on the trip meter by the number of gallons it took you to fill up.

Also, using A/C and turning your car off and on multiple times in a day are some basics that will lower your gas mileage.
Hope you find out what the issue is.

Or even better, do this over three or four fillups. Just keep a piece of paper in one of your storage compartments with the pertinent data.

And as said above, 19 mpg is far from what you should be getting - with the i4 you should be getting around 26 to 28 mpg easy with 75% highway driving.
