Nissan Altima Real World MPG



  • Yes, the expert did drive my car before our conversation. He got great mileage: presumably this is part of why he was impatient with me, since in his mind he had already spent an hour proving that there was nothing to complain about.

    Of course, an expert driver paying attention only to his mileage, filling up the tank literally next to the onramp and and then the offramp so that he drove 99% on a freeway, was always going to get great mileage. He proudly showed me his receipts, proving he got 35mpg in my car. But I have effectively tried the same experiment, driving a couple of hours each way almost entirely on freeways . I got 32 mpg. (My OBC said I had been getting 35 mpg if you trust that more than my own fill-drive-refill-divide calculation.) Yes, my car can do it; no, I'm not an inherently gas-wasteful driver.

    So why *have* I been getting between 14 mpg and 19 mpg on almost every tank of gas since I got the car (new)? The one surprising answer I have been given is that really short trips give really terrible mpg. So a (very) short commute does save me money on gas, but not quite as much as I would have thought.

    It had never occurred to me that my car would burn significantly more gas in the first mile or two, revving fast in a fuel-inefficient effort to warm the catalytic converter quickly. It may not even be true. But I figured it was worth sharing the idea here.

    If the kind of driving you do most of the time is very, very short trips of less than 3-4 miles or running a bunch of errands where you start and stop the engine several times in a relatively short trip, then you are going to get the worst possible mileage. And that would be with any car but the newer cars it may even be worse than the old ones. The EPA city mpg test is not nearly as severe as I described above so you should expect significantly less MPG thant even the EPA city rating for your vehilce. Remember they try to simulate a lot of differnent kinds of city driving to come up with their city rating. Even the city rating will have a range associated with it and it sounds like your type of trips may be on the lower end or even lower than than the lower end of their city MPG range.

    Comparing a car that is ten years old or older may not be a great comparison as these new cars are tuned a lot differently to get that high MPG in normal situations. If your situation is well off of normal than you may even get worse MPG with your newer car than with an older one if that makes any sense to you.
  • So far straight premium.

    Just had another almost 600 mile trip - came in at 32 mpg, mixed driving, over steep mountain passes.
  • Few questions:

    I have my altima for 2 weeks now and the guage shows me 28.4 mpg (may be bcs all of my driving has been in city and yesterday was stuck in traffic for 45 min due to acc) how to reset those numbers? I've yet to take a long trip on freeway and than see how the mpg numbers behave

    One of my relative adivsed me to use premium every 4 - 5 fill ups that will extend engine life. Is that true? Can I do that? Has anyone any exp of how it affects engine?
  • It is very sad that my 2011 2.5 Nissan Altima Coupe can't get better than 27 MPG on the highway. I do like quiet and comfort of my Coupe. I traded my 09 Civic hybrid in on this and I got 45 to 50 MPG all the time. The stated 32 MPG on the EPA window sticker was the deciding factor. Nissan grossly over estimated ergo... it was a lie. I don't know anybody that gets my 27 MPG let alone the 32 MPG Nissan advertised. I could have got the 3.5 or better yet a Mustang 5.0. I won't be buying a nissan again.
  • I have a 3.5 liter Nissan Maxima. Bigger engine than your 2.5 and the maxima is heavier than the Altima but I easily get better highway mileage than what you are getting. You should be getting much better MPG. It should be easy to get the EPA's numbers or better. Most people I know get much better MPG than what you're experiencing and most get better than the EPA.
  • My 2.5 S Altima has run 13500 miles but is giving a mileage of 8-9 MPG in New york city.
    I am frustrated by its performance and the consumer Affairs of Nissan is of no help.
    Any suggestions?
  • There is nothing you can do. i own an 07 2.5 with only 40k on it and my gas mileage is horrible ( 15 mpg average ) i tried everything! to no avail. spread the word and sell it. do not listen to anybody who says its because you don't know how to drive. it is the car!!!!!!!!!!! :(

    Short trips = lower mileage. Having driven in NYC myself, I'm not surprised that its so low. You obviously make very short trips or you'd have more than 13k miles on a 2 year old car.

    When is the last time you reset your mpg display. to get an accurate mpg you need to reset it right after every fill-up otherwise it will display the average mpg since the last time it was reset. How many months/miles have you driven since your last reset?


    Page 2-18 of the owners manual
    Average speed mode
    The average speed mode can be selected to
    display the average miles per gallon and miles per
    hour since the last reset.

    Remember, when you are stopped at a light (or by traffic), you are getting zero miles per gallon. That will drastically affect your average MPG.

    2013 Altima 2.5 SV. When I drive at least 50% highway not exceeding 70mph I get 30-32 mpg. If I do a lot of suburban driving it drops to 26-28mpg. For the size car it's OK. I traded a 2005 Malibu Maxx that got 24-28 mpg in similar driving. I think poor fuel economy is mainly do to the great weight these modern cars have compared to the past. All the safety equipment that is saving lives and reducing injuries is a fair trade off to me. Everytime we stop at a traffic light it takes a lot of fuel to get these beasts moving.

    I've had my 2013 Altima for 4 weeks (tomorrow) and I've been getting about 26 mpg in mixed city driving. I'm expecting that number to go up as the car breaks in. I have about 850 miles on it now.

    I just drove 500 miles through combination of mountains, curves, and some straight flat roads. Central Oregon to Sacramento area. I set the trip computer at the start and the average mpg was more than 41! I was not driving in a manner to save on fuel. I still had more than 1/4 tank upon arrival. On the trip back I drove as fast as was safe. 70-75 whenever possible. Having reset the trip computer I got 38.5. The reason I purchased the 2013 is that I drove a rented 2011 last year for 8200 miles around the USA. I was astounded to get 39-40 through much of the trip. I drive little in stop and go city traffic. A hybrid is better suited for that.

    10,000 miles so far.

    Screen average is 25 point something.

    Several long highway trips consistently give 34 mpg.

    Not much to complain about for the power!

    I just completed a 900 mile round trip between Atlanta and Louisville and I averaged about 38.6 MPG for the trip averaging about 70 MPH along the way.
