I am experiencing similar MPG numbers with our 2.5 SL but I only use 87 octane and 10% ethanol. That little bit of ethanol results in a 3.4 % loss of power and effeciency so I have a tough time with the vehicles operating with optional E85. I have to believe it will really trash economy and power.
 
For the immediate future the purchase of 100% gasoline will be pretty scarce or until the government subsidy for corn crops is dropped. Not only do the oil companies have our politicians wrapped up but outfits like Cargil, Peavey and ADM have a pretty tight, controlling hold on the purse strings of congress.
 
Enjoy the car and smile when the guy in the F-350 pulls into the next stall and drops $150.00 on diesel.

Looking forward to posting results here and at the petrozero.com fuel saver forum site. Thanks for everyone who've taken time to post your results. It has sold me on this car! Best mpg short of a hybrid...

You're right. I tend to get geo-centric around the boards since a vast majority of posters are from the US.
 
Sorry!

OK I just filled up my fourth tank. On my first three I really babied it. Slow starts and acceleration etc. My first three fillups ran 26.3, 26.3 and 25.8. This was with about 80% city/suburban - 20% highway.
I was satisfied but not particularly thrilled. Then I said the hell with it and started driving the way I've always had with a medium heavy foot to accelerate and then letting off when I hit my speed. The results were 522.2 miles with only 12 miles highway and my mpg went up to 28.3. Now I'm very happy!
If you watch your mpg gauge you'll see that after you let off or maintain your throttle the mpgs go up to the 60 mpg mark. The only time you really burn gas is to accelerate and the sooner you hit your speed the better.
BTW, 522 miles on a tank is great and I still had 1-1/2 gallons left though the computer said I was empty. By my calculations I could have gone about 570 miles on the tank for virtually all city/suburban driving.

I drive a 97 Altima 2.4L 5spd manual.
A year ago I was averaging 32 mpg ( my car is rated at 29 hwy)
I started reading about hypermilers, and did a few thing differently, inflated my tires to max sidewall rating (44 PSI), coasting more often especially when red light were approaching, etc. My mileage went to 35. I was pretty happy.
I kept reading. I finally decided to drive a little slower, I was driving 75-80 mph in my commute. I lowered that to 55-65. My mileage for my last 2 tanks are 42.1, and 43.0 MPG.
Its possible to get great mileage out of these cars if you change your driving behaviour a little.

08 Altima 2.5 w/CVT
  These past six months my mileage has improved slightly, after a front wheel alignment and breaking in the motor.
On the open highway in Texas I drive 400 miles between towns often. I donot fillup till I arrive at my destination. At first I got 33 mpg more or less depending if I use the AC. Now I get an avg of 38 per the car's trip computer if I donot use the AC. This driving 65-75 with very little traffic or towns in between. I am very happy w/mileage, but I do not track use intown as of yet.

Trip meter,can I trust it? by ndiboy

I bought this I4 2002 Altima with 73,000 miles in January 08 used.I have been averaging 18.8-22.3 in the cith and 26-31 on the highway.When i use pen and paper there are some discrepancies as reported by other contributors.
I have also noticed that sometimes i need to reset the mpg meter to get something near reality e.g after a highway trip reading of say 29mpg by the time you enter a city you expect it to go down but sometimes it either stays there or takes time to come down and Nissan says it updates every 30 secs.
When I am in such situations, I reset it and it comes down to b/w 21-23.
Has anyone observed similar things?

2.5 S. Roughly 18K miles. 27.5 MPG over ~2 yrs in Milwaukee. For those who don't know, it goes below 0 in winter, so impacts my MPG significantly. I use the lowest octane gas. I am a very careful driver. Use lots of cruise and don't accelerate too hard, though I find it really tempting to just floor it

Very similar to neo. 2008 2.5S, owned for 19 months, 22+K miles - getting 27-30 mpg consistently but here in Texas I don't have cold temps....
