    I have a 2007 2.5 CVT and the trip computer overstates mpg by at least 10%.
    I get 27-28MPG at 70-75MPH. You can actually exceed the 32MPG if you drive
    55-60 MPH on the highway. This and the brakes are the only complaints I
    have with 62000 miles on odometer. Front brakes have been replaced twice
    and I am easy on brakes.

    Well, you are not alone. The meter MPG most times are wrong. One needs to drive and fill up the tank to be able to get an accurate calculation. I have a 2.5s with SL package 2002 Altima rated 23 and 29 city and highway respectively but even with the meter I get 17 -18MPG city but after fill up and calculating I always get b/w 16-17 MPG. On the highway most times meter reads 29.1 - 32MPG but my calculation lands me in 27MPG. I have learnt to ignore the meter reading because most times it is wrong and misleading. The one that annoys me most is that of city driving, for a 4 cyl 16MPG is just too poor and too bad for the Altima.
    Can anyone help, what can I do to improve the city MPG?
    Thanks Onuchukwu C.E.

    I live near Corpus Christi, TX. 2008 Altima gets 24 - 26 on hiway and 17-18 city.
    Recently went to Grand Canyon. Economy increase to 33 - 35 hiway. On return trip as soon as I passed El Paso economy dropped to 28. Has to be a performance chip/hi altitude compensation issue. Any thoughts? :(
  • ikeupikeup Posts: 5
    Engine is a 2.5 CVT. The 24 to 26 hiway and 17 to 18 city is from the computer. As was the 33 -35 hiway in Arizona. My mileage started climbing during the trip to Arizona somewhere around Roswell, NM where it increased to about 30. Then as we went further north and west it continued to climb. On the trip from Williams AZ to Grand Canyon and back to Williams, the average was 39. Then as we got closer to Texas, it started dropping. I can only think of 2 reasons it would behave this way. Quality of gasoline, I only use unleaded regular and Arizona has better gas, or altitude compensation in the computer. Possibly leaning the fuel mix at high altitudes and over enriching at lower elevations. Ed HIcks Nissan dealership in Corpus Christi, TX are clueless and say they cannot help me as there is no error code to read.
  • Just bought a '10 2.5l coupe, specs say 32mpg hwy...which is misleading because those mpg #'s are derived under perfect indoor conditions. My first 2 tanks I got 20-23 mpg on the highway!!! I'm a commuter so 90% of my miles are hwy miles. This is why you don't get good mpg. Lead foot, AC, wind resistance, hills, quick accelerations, tire psi etc. Goto http://www.fueleconomy.gov/feg/driveHabits.shtml, there's a chart of MPG vs. MPH. Anything over say 60 MPH you drop substantially in MPG. At 75-80 MPH you're lucky to get 20 MPG under the best outdoor conditions, e.g., no AC on, low wind, constant speed, no hills. Thanks to George Dubbya the standards used by the EPA to calculate MPG were lowered and the #'s are now more misleading than ever before...great for the auto and oil industries but crappy for us consumers.

    Actually the standards were raised for mpg. The numbers were lowered. My car was 34 mpg highway and it is now 31 mpg highway.

    FWIW I get way way over the EPA numbers with a lifetime average of 34.6 and dozens of tanks over 40 mpg.

    Hi, I hope it was fixed already. If still required, I would suggest to check either CO2 sensor(s) or Knock Sensor. These two parts are crucial for gas mileage. Hope it helps.

    I have a 2010 Altima V6 CVT sedan with 6k.

    If the entire tank consists of only short 1-5 mile trips, then 17-18 mpg is what I get. A/C usage or lead foot driving does not seem to make much of a difference.

    If the tank has about 1/3 highway, then I average between 21-22 mpg.

    If it is 100% highway, then it ranges between 26-30 depending on the speed, load and terrain.

    All of these figures were obtained with 87 octane, as recommended.
  • I am here to tell you - that my 2007 2.5 s - gets terrible gas mileage, I drive very light footed and dont run up on lights or tailgate.. and use my brakes very infrequent, (conditioned from my chevy blazer 97). Anyhow, i live in east TN - and the car is used for my wife to go to school and back and getting groceries - and a few out of town day trips to atlanta. my wife has one short bybass road to commute to school (1 light 45mph-flat 3 mi.) and rest is interstate about 5 mi. she goes 5 times per week back and forth -- other than this she goes to local shopping district home depot,kroger ,mall etc.. all about 6 mi from home - 1 light on the trip - 40 mph rd one hill. we have yet to average better than 19 in the city - and our best on the interstate 65-75mph speed is 26 maybe 27 mpg. - that is way way less than expected- ac off - no load in the car just two people. car cleaned and waxed - fresh mobile 1 oil and tires at 35psi. nice weather no wind about 55 degrees/ - i dont care how they rate or when they changed - every car i have driven and owned in the last 20 years has gotten precisely the milage rated - my 79 ford granada, my 83 camaro, 81 mazda 626,85 subaru, 90, mustang GT, 97 chevy blazer. all of these got their ratings - i did get some freakish good milage something 55mpg with my 4cyl camaro once for one tank of gas. - i can only attribute to the gas or maybe some tail wind.. could never explain it -it as isolated incident. my blazer gets its milage loaded or unlaoded go into wind or against - this is usual for bigger engine cars - and small engines will see more impact from hillls and load and ac. as expected.. however driving habits load - or ac - can explain how the f*** they can tell me that these cars can ever achieve anything close to the 26-35 that was on my window sticker - i get about 7 and 8 miles per gallon less respectively . and there is nothing that someone can tell me to explain this - and i buy gas here or atlanta -makes no difference - i shop and regular brand name stations exxon ,shell, bp - so forth - anyhow ,my combined driving in my low steady city whcih accounts for 1 light in 6 mi of 45 zone./ which to me sounds like optimal hwy drivewaying conditions as mentioned in the forum - that 45 55 steady would yeild best - and yet i get no more than 21 combined.. this maybe 3 mi better per gallon than my 97 blazer. its so close -that when we fill the cars - there generally is no noticable differnce of whicih we use. for what .. and they say suv's are gas hogs/ if this how they are rating 4 banggers - i got news - i will buy suv for ever - never affected by ac load hills wind - etc.. and look as if they get = millage.. so i will never buy a nissan and 4 bangger again . an di am all for eco friendly but next time some says somethign about my gas hog suv , i will beat them down so far.. i have no idea how you people can manage to get 30 plus mpg. i know there seem to 2 types in here - those who get crap milage like me and others who get significantly more - like the rated.. sounds to me -as there are some cars comming out of the factory with computer settings wrong.. some how. or bad sensors...

    I now have 31000 on my 2009 Altima 2.5S. I get between 26 to 33 mpg and usually about 29 in mixed driving. In summer weather 32 to 33 on a highway trip is normal if I keep the speed 70 or below. All numbers are real world calculated. I have had zero problems with the car but wish it were a manual transmission. I looked and looked for one but could not find one. My 1998 Camry with a manual transmission and 145000 on the clock will still get about 36 on a trip so I am not thrilled with the Altima's mileage. I am currently looking to sell the Altima and get either a Hyndai Elantra or a Cruze ECO. :D

    I am leasing a 2011 Altima 2.5 S through my business and the mileage sucks, 16 miles per gallon !!! come on !! i am easy on the gas pedal, and never went over 60 miles per hour, not only that, when I am at a light I put the transmission in neutral or when I am going downhill. After the lease ends I will get a manual transmission car, whatever the brand is.

    I purchased a 2010 Altima coupe with the 2.5 engine.This thing is bad on gas for a small car.I thought it might get better after breakin ,but 7 months later,i found out i was wrong.Real world driving by my wife in suburban town,rarely into the city,my best average has been 22.4 mpg.My wife loves the styling,and i hate the mpgs'.The car we replaced was a 2002 Chrysler 300M,a v6 with 250hp and much bigger.I was able to get about 27 highway and 21 local mpg.I'll never buy another Nissan,I wish I had read this forum first.VERY DISAPOINTED in Cherry Hill.

    I posted a message last year about getting over 35 mpg on a trip to Arizona. The minute I filled up on the return trip near El Paso, TX, my mileage dropped to 28.6 mpg.

    Since then my combination driving has been between 18 and 23 mpg. Nissan Altima's get horrible fuel economy. I have a friend who owns a much larger Toyota Avalon that gets 26 combination and 34 highway.

    30 mpg with a 2.5 Nissan Altima is impossible.

    For example:
    Today 6-25-11 I reset the mpg computer in Corpus Christi, TX, drove 30 miles home, near Sinton, TX, and computer said 28.6. I drove 15 miles one way to Taft, TX and back, which included going through Sinton, and my mileage is down to 24.4. This is mostly highway driving at a maximum speed of 70.

    This may be coincidental, but I have noticed that all the gasoline pumps in Corpus Christi, TX, area say fuel contains 10% ethanol. Perhaps this is the problem.

    You are exactly right, If I get 16 miles per gallon in town with my 2011 Nissan Altima 2.5 S it's a miracle. I leased it on March 14th, 2011 and it has 1245 miles. The best that I got it's 16.5 miles per gallon, I will never buy a Nissan again if they do not fix this when I take it for the first service. Those getting great gas mileage maybe have different settings, but still cannot believe it.

    I recently leased a 2011 Nissan Altima 2.5 S i'm still getting used to the CVT transmission i do a mix of highway/city driving, ive noticed that i average between 24 and 26 MPG the window sticker shows 23 city and 32 highway. So far i have 700 miles on the Altima and from reading the previous postings should i be getting better MPG ?
  • ikeupikeup Posts: 5
    I I could get 24 - 26 combination, on my 2008, 2.5S, I wouldn't be considering going back to Toyota.
    Yesterday I drove around 60 miles from Sinton into Lowes in Corpus Christi. 70 mph, cruise control on, put A/C on recirculate, shut off compressor on inclines like overpasses etc. and only received 27.9 mpg for the trip. I have 69,000 miles and this is as good a highway mileage as I have ever received in Texas.
    When new my first long trip was to Nebraska in February. I didn't use A/C and got 34 mpg on highway. The difference I attribute to not using the A/C.
    Last April I documented a trip to Arizona. In Arizona I was over 33 mpg. When I returned to Texas I filled up in El Paso and was back to 28 maximum on highway.
    Arizona and New Mexico has a lot more hills, mountains and inclines to reduce mileage. So I must conclude that Texas' 10% ethanol takes it toll.
    Nissan, Ed Hicks Nissan, can furnish no answers as to the difference.
    What really appalls me is the fact they wont even attempt to help.
    They evidently don't even have the means to test my vehicle to see why it gets such poor economy. The service techs say "If there is no check engine light we cant fix it."
  • where do you get the K&N drop-in filter and what else do you do?
  • I've got a 2009 altima 2.5s. It has 45k miles on it. On my adventure across country with the car loaded with 3 people and some other things I just got from vancouver WA to just outside Boise ID on half a tank of gas! I love this car! That's almost 45mpg hwy the whole way! Suck it prius drivers! :D

    Wow, that's impressive. I can only manage to get around 32MPG here on PA turnpike. I think we have too hills here. If I push my speed to 80MPH or more, I only get about 29MPG.
  • ikeupikeup Posts: 5
    If I accelerate slowly, put the cruise on at 70 mph, tap the brake and coast 1/2 mile to an exit or stop sign, I can get 22.5 mpg. That's on flat land, sea level in the Corpus Christi, TX area.

    2008 Altima 2.5S, 66K miles. Service done at Ed Hicks Nissan in Corpus Christi, TX. There is nothing wrong with my engine. I'm told it's my driving habits. Evidently driving like there is an egg between your foot and gas pedal doesn't work on Nissan's.

    I'm wondering if I need to drive it "balls to the wall."
    Maybe my gas mileage would improve if I drove the heck out of it.
