    2002 Altima QR25DE, 2.5S, In summer with AC on, Florida interstate 31 mpg at 60mph, 29 mpg at 70 mph, 27 mpg at 80 mph in summer. Winter you get more mpg in the highway long trip, but less mpg in short trip (rich mixture when engine is cold). I already passed 105k miles.

    Just drive slower, more relax, enjoy the view = higher mpg.
  • 2008 Altima 2.5s. I have 73,000 on it and 28 mpg city and 38 mgh

    drive slow homie

    I was concerned after reading about low mph from owners. I bought my 2011 2.5S and after 1500 miles I'm averaging 32.5 combined. The optimistic computer says 33.6 much like others have reported. I'm very happy with it and am looking forward to improving it.
  • i will never get over 25....... never~~~~~i drive 80% local... i usually get 19~~~ about 400per tank.....i've talk to nissan's tech guy.they told me its normal~~~sad........
  • I am getting horrible gas mileage on my new altima with only 2,000 miles. I do about 80% city /suburban driving and 20% highway. My trip computer reads 19 mpg. If I reset it, it will start around 16 mpg and move up to around 19 mpg after half tank. But at half tank I only have around 160 miles on the trip odometer. It's horrible.

    My car has the automatic dual zone climate control. I'm thinking that leaving it on Auto is seriously degrading fuel economy because the AC light stays on all the time, although I'm not sure if the compressor is on. No matter how conservative I drive (coasting/slow launches etc/55-60 mph on highway) my mileage is this bad.

    Any suggestions?
  • I have you all beat!! my 2.5 altima sedan with 39,000 miles on it gets 11.5 mpg city and 18.5 mpg 75% highway and 25% flat country road. this car is well maintained and i do not have a heavy foot. i have checked this a doz times! (always the same.) nissan and there dealers say if there is no check engine light on there is nothing they can or will do. i know 11.5 mpg city for a 4 cly sounds crazy but it is fact!!! :mad:
  • me too i get and average of 18.8 - 19.2 mpg city. I try everything to increase my mpg by driving conservative like you and still i dont increase my mpg, sucks. I do 98% of my driving city

    ^ The Altima, or any midsize sedan or bigger, in the car industry is not a smart or wise decision if you live in the city and/or primarily do most of your driving in the city. Unless you spend the money and get a hybrid, no midsize or fullsize automatic or CVT equipped vehicle is going to get great gas mileage or even meet's its suggest city mpg. All that stop and go traffic, low speed limits, etc wreaks havoc on gas mileage, not matter what car you have. It's not really the car's fault you do almost all city driving. I have the opposite experience, nearly 80% rural city/highway driving and maybe 20% "actual" city driving. I'm getting great mpg out of the CVT so it is possible.

    If you live or do most of your driving in the city, you need to think ahead and stay with the lighter, more fuel efficient small sedans, compact sedans, hatchbacks, and/or hybrids if you want to have great mpg.
  • how many kms on a tank do you get? im 50% city and 50% highway and i get only around 500km on a tank when it should probably be around 650 on a 75litre tank. i dont speed or rev the engine and coast to stop lights/stop signs
  • smarty666smarty666 Posts: 1,503
    Well, I actually don't have an Altima. I have the Maxima with the 290 HP V6, but I get about 440-470 miles per tank right now, and that is using premium.

    Own a 2012 2.5s has around 800 miles on it after around 2 months. My driving is 80% highway and the mileage is unbelievably bad. I'm averaging around 22 mpg with delicate easy driving, easy acclerating. The mileage on this 4 cylinder is worse than on my 6 cylinder 4wd suv!
    I'm stunned at how poor the mileage on a 4 can be.
  • smarty666smarty666 Posts: 1,503
    First off, your still in the break in period. I got better gas mileage after a few thousand miles were on the car around 3-4k. Second, you can't be much of a light foot or take an easy on your car. It makes no sense that I'm getting 24-25mpg with 290 HP V6 and your getting 22mpg with a 175 HP I4, no way in hell that is possible.
  • jonhnjonhn Posts: 2
    smarty666, you know nothing about how I drive, or what is possible. Many posts here prove that the Altima 2.5's have terrible mileage- some worse than mine. Also, my 6 cylinder suv gets better mileage - with me, the same exact driver, driving it.
    Don't comment when you don't now what you're talking about. What I posted is fact, I drive the altima conservatively and live in a very flat state - central ct. - no big hills here.

    I have had 3 2.5 Altima's in the last 12 years and have had great gas mileage with all of them. My latest is a 2010 Altima coupe with a 2.5 that I drive for work every day and put about 500 miles a week on it. I get 27+ MPG! Those are my Facts...

  • This is what my mileage looks like:
    http://flic.kr/p/buwKw8

    I reset the trip odometer to 0 when I filled up. I filled to 2 clicks just to be sure it was full. After a mere 82.4 miles, my tank is nearing the halfway point.

    Not that the fuel guage is accurate either. Even after filling up, it doesn't always read completely full, or it fluctuates up and down. After I took this pic and drove off, the guage actually went up a bit.

    But you can see the AVG MPG is 18.1 MPG, and AVG Speed is 17.7 MPH sue to city driving. And I am not dogging the car. I coast to red lights and don't gun it. Just normal driving.

    The mileage is horrible. I would have just bought the V6 if I knew the 4-banger would be so bad on fuel.

    john, you know nothing about how to get good mpg out of a car. Many posts here prove that the Altima in both I4 and V6 version can get good mpg. Many on the Maxima forums are getting incredible mpg and that car has a much more power engine and takes premium no less.

    Don't comment when you don't know what your talking about. What I posted is fact, I drive conservatively and live in pretty flat area of NJ - no big hills here.

    (1) Use a top tier quality gas company, i.e. Shell, Chevron, etc

    (2) Try to use the same gas pump at the same gas station each fill up. Reset the avg fuel economy display/history immediately after each fill up.

    (3) Check your tire pressures and inflate them to just above the recommended PSI on your door sills, I usually recommend 34-35PSI cold.

    (4) Don't overload the back seat and trunk with heavy bags, equipment, etc.

    (5) Use the cruise control as much as possible.

    (6) Coast to a stop when possible.

    (7) If the temperature is not too cold or too hot, don't have the heater or A/C going in the car.

    People who are getting poor open road gas mileage on a I4 Altima are either (A) not doing any of these measures or (B) have one of the few bad glitch cars that every automaker has. There is no reason why people like me who have a V6 Maxima, and others with I4 and V6 Altimas can get decent gas mileage out of these cars. That means its possible.

    It's fairly clear that something is going on with the low mpg Altima.

    The suggestions you gave are all great long-term tips, but in the short term, the gas going in the tank has to be going somewhere, enev if it's just leaking onto the ground.

    Areas I would start examining...

    Does the car "free wheel" coming down a hill with the transmission in neutral?

    What do the brake pads look like...are they dragging?

    Avoid any really short trips that don't allow the engine to warm properly. Cars run much richer until normal operating temperature has been reached, burning more fuel.

    Have the exhaust gas analyized by a local mechanic... Is it running far too rich?

    Let a trusted friend drive the car for a week or so, keeping detailed records on gas placed inthe tank and miles driven. Maybe let him run it down the highway for a 200 mile round trip, filling up immediately before and after, then calculating the mileage.

    You get the idea.

    Such low mileage is way outside the standard deviation for an Altima. This is something that is fixable. You just have to locate the cause before it can be fixed.
  • Hi all,I posted about this 6 months ago.I am still concerned.My 2010 Altima coupe with the 2.5 engine has been doing very poorly also.As I told everyone months ago,my older 2002 Chrysler 300m got better mileage with the 250hp v6 engine .My wife mainly drives the Altima to and from work in a suburban setting with few traffic lights.I have never been able to get over 22.4 mpg,even on longer highway trips.After all the feedback here,I now know that the Altima is not a good choice for fuel economy.i might even follow the action of the Honda lady who sued Honda over poor mileage and won a decent settlement.Maybe then the window sticker will reflect real world mpg,not some bs.My next car will not be a Nissan.TELL the world people.Nissan has poor mpgs'

    Lots of big variables in comparing real-world MPG experiences. City driving with lots of traffic jams at rush hour will yield much worse MPG than driving same route at 11PM when roads are open. Idling a lot while sitting in parking lots (which I see too many people do regularly) can be HUGE gas waste. Lots of short trips hurts mileage a lot too (30-50% since engine is much more efficient after it warms up). Jack rabbit starts between stop lights also hurts city gas mileage a lot. Highway driving at 75-80mpg into a head wind may give literally 30-50% less MPG than driving 60mpg with tailwind.

    FWIW- Driving moderately (smoothly keeping up with traffic) my 2010 Altima 2.5S sedan (~15k miles) consistently gives me 27-28mpg city/suburban (10-15mi trips) & 33-35mph highway (70-75mph). Those #'s are from actual gas used over last 5+k miles. IMHO that's good real-world economy for very decent car with lots of room (and NO hybrid headaches).
