do they adhere to california emission standards? If they do, I'd deffinitly ask the dealer about it. there is a known probem with the altima that are built for those standards with cold start up. Nissan has a service bullitan out about it. As I said, the cure is very simple. they just need to update the ecm. check this link that townboy325 put in his post.

I got my 2.5 SL about a month ago and go about 650 miles on it so far. I'm driving work about 5 miles locally with lots of stop sign (about 10). I'm getting 20.
sellcar, did you have a dealer to check your engine? I wonder the result.

My 2007 3.5 SE with 3,000 miles got 24.3 MPG on its last tank neck-to-neck after driving just 222 miles--mostly highway using the AC. On tanks where I've driven upwards of 300 or more miles mostly highway it's gotten low 26. It's MPG meter showed average of 28.2 one time, but usually stays in the high 26 range. Hasn't used a speck of oil--still 3/4 full since taking delivery on 12/21/06. As you can tell, I don't drive it very much--stay mostly in a 1990 Festiva 5 Spd I bought on 7/5/04 with 159,000 miles on it for $300--it now has 181,000 on it--get 39-41 MPG everytime I fill up. Changed timing belt and clutch for $750--I'm shooting for 200,000...

Question about mpg

I'm having 24 mpg from my calculation with 40% city and 60 highway with the new 2007 2.5S, is it abnormal? I always have AC on at low, and I'm not an aggressive driver.

I've read several places that the mpg will increase after you get over 2 or 3k. something about being programmed to run a richer fuel mixture to assist in break-in. not sure if its true though.

Yes, Altimas will get better mileage after about 2-3 thousand miles. One reason for this is that everybody drives differently. The computer will actually make adjustments according to the way you drive. I have friends that drive interstate almost exclusively. They are getting 31-32 MPG. By the way, some Nissans do say premium fuel recommended. All Nissans run just fine on 87 octane fuel.

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.
