#42 of 51 Reminder not to trust the trip computer for gas mileage by jg28 Jul 02, 2007 (6:47 pm)
The trip computer for Altimas or Maximas will consistently give you faulty information regarding MPG. Do it yourself. Most likely, you'll be disappointed. My trip computer (2002 Maxima) consistently says I'm getting 24-29 mpg but I've never done better than 24 (okay 23.7) when actually computing it. The low fuel warning is skittish since I've driven on what I thought was fumes and have never put more than 17 gallons in my 18.5 gallon tank.

Replying to: jg28 (Jul 02, 2007 6:47 pm) Thanks for the valuable info. My 07 Maxima holds 20 gallons and my first fill it only held 14.   How's your automatic seat? When going forward, I have to lift my butt a little or else it's stuck. But going backwards, I don't have this problem.
#44 of 51 Mileage on my '03 3.5 ltr maxima by windy6 Nov 23, 2007 (2:00 pm)
I just checked my TRUE mileage, 165 miles, nothing but in town, average trip about 6 miles, 18.2 MPG on 87 Octane.   On a recent trip to and from Austin to Denver I realized after my first two fill-ups that driving my "normal" 75-77 MPH wasn't going to get me there a day earlier, since it's a total of 935 miles door to door. Deciding to see what I could "milk" out of this by dropping my speed to 65 +/- was a very pleasant experience. Especially as this was the week that gas was going from $2.80 up to $3.00/gallon.   Two tanks at higher speed; 24.4 MPG. 4 tanks (actually 4 fill-ups on all highway) averaged 30.3 MPG.   BTW, those "all highway only include about 175 miles of Interstate, the rest is 2 lane and 4 lane with a fair amount of smallish towns mixed in. Pretty nice cost savings.   If we all did this we could take some real money out of the pockets of the sheikhs.   windy6

Replying to: hercgretch (Jun 24, 2007 10:47 am) Hello, I also have a 2007 Maxima. I found the fuel problem the first time I filled the tank. I took it back to the dealer and they said that was normal. I plan to complain to Nissan. I suspect they put the Altima sending unit in the Maxima to save money. (the Altima has a 15.9 gallon tank). I'll post Nissans response.

Replying to: craig777 (Jun 27, 2007 1:24 am) Craig, I live in Tampa, Florida and I have been able to request certain cars to drive as rentals at Enterprise Rent-a-Car. I've rented Nissan Muranos in the past. It helps that the location where I usually rent from is across the street from a Nissan dealership also. So you might want to give your nearest Enterprise Rent-A-Car location a call and see if they might be able to assist you. Good luck!
#47 of 51 Recent MPG and Trip Computer by poodog13 Jul 08, 2008 (11:00 am)
2006 Maxima SL   Recent trip from Pittsburgh to Myrtle Beach yielded 28.5 MPG at 75 MPH including some distances through mountainous terrain. Level land actually got me around 29 MPG. I typically do mostly city driving in high traffic conditions and struggle to average 18.5 MPG so I was very pleasantly surprised.   As for trip computer DTE and fuel guage, I have the same issues and have just learned to deal with it. I consistently get only 16 gallons when both show as being dead empty. I agree that this was most likely done on purpose so that a mis-read by the system doesn't run someone empty and most likely was done after some testing of the tolerance interval of the computer's measurement accuracy. It's hard not to keep that in the back of your head and run it down further sometimes.

Replying to: guyverfanboy (Feb 08, 2009 6:33 pm) I've got an 2009 Maxima. 4000 miles on it. I've had it since August and love it!! Overall, my average has been around 22mpg (combined city/highway). If I go on a road trip, I average between 27 to 28 mpg.

Replying to: cmyawn (Apr 01, 2007 9:37 am) I just got a 2007 Maxima SL this weekend. I observed the same thing with my first two fill-ups; when the gauge shows nearly empty, the DTE shows 60+ miles and 14 to 15 gallons will fill up the tank. I suspect it's just Nissan being overly conservative to cut us drivers some slack. Replies to this message: poodog13 (Apr 28, 2009 9:57 am)

Replying to: andy211 (Apr 27, 2009 12:32 pm) Agree, I've never gotten more than 16.5 gals in my 2006
