I have over 6,000 miles on my 2007 Altima 2.5 SL and my mileage stinks. I tried filling the tires to 35 psi and no change. I had the computer reprogramed by the dealer and still no change. I don't think this car will ever get good gas mileage or even close to the lowest mileage that is rated on the window sticker. I just think, it's just a gas eater  20-23 MPG Tops! I think Nissan gave a high rating about how much mileage this car gets because they know fuel is high and getting higher and they want the lead on the other automakers to show there car gives better MPGS then the others. When I think about it, the engine is larger then Toyota Camry and Honda Accord's 4 cyl. but the window sticker on the Altima 2.5 says it gets more MPG'S then thiers. I ask, how can it get better fuel mileage then the others that have smaller engines? Yes, I know it's a larger engine and it will give more take off power, but will pay in the price of gas.

Manufacturers don't set the MPG numbers. The EPA does and it's only an estimate. For 08, they have adjusted the figures. You only have 6K miles, give it about 10K. You're still within range of the EPA range estimate.
I had a 07 Civic that got about 23-25 mpg.

Everyone that I have talked to is getting at least 25 MPG out of a 2.5S or SL. If you have not cleared your MPG guage, it reads an average what it has read since the car was completed and put on the test track. This is usually around 4.0 MPG. Go to www.fueleconomy.gov and you will see the ratings for 2008 model cars. These are actual mileage ratings from the EPA. You will notice that Toyota and Honda were the ones deceiving their customers. Nissans ratings were actually pretty accurate. Up until this point, cars had to be driven only 40 MPH, with no AC, windows rolled up, in perfect weather conditions for mileage rating tests. Besides, sometimes larger engines do give better gas mileage because of the weight of the vehicle. A larger, more powerful engine will have to work less. With a CVT transmission, you don't get as much "over-revving" as you do with a conventional automatic. Your RPMs will stay lower and thus causing the engine to work less. If you drive the car hard, you will not get good mileage. That is true of any car. Recently, I had to use a Toyota Avalon rental. The mileage I got was worse than my wife's Murano which has a larger engine.

My car has a pinging sound when I start out from a traffic light. I took it back to the dealer and they reprogramed the computer, but it still pings. The dealer dosn't know how to fix the problem so they are getting in touch with Nissan Motor company. Anyone having this same problem with there 2007 Altima 2.5?

Uh, I don't believe the Murano has more power
than an Avalon. Avalon has, I believe, 268 horsepower and the Murano has 244 horsepower.
So you should see less mpg's with the Avalon than with the Murano.

Never did I say It had more power. The reply was to a post that said a larger engine should get less mileage. As far as the Avalon goes, most I got out of a tank was 325 miles. I get better than that out of my Frontier with a 4.0 V-6.

Back up - how does having more hp mean fewer mpg? The Avalon will get much, much better mpg than a Murano.

Didn't for me. My wife's Murano averages 22.8 MPG. The Avalon I rented got 20.8. Could be the mechanical shape of the 2 vehicles. My wife's Murano is pristine. The Avalon was, well, a rental.

Just wanted to report that I got 33 MPG on a 250 mile trip. Was traveling 68 - 73 with the cruise contol with A/C part of the way. Only have 1000 miles on my vehicle. How can I expect mileage to actually get better? Should I?

It might get better, but 33 is pretty damn good if you ask me!
I get 29 with my '05 3.5 under similar conditions.
