    New 05 3.5SE 5M with 300 miles on it, 27 MPG at 70-75 MPH using trip computer.
    If this is right very happy. Ole MIke

    2002 Altima 3.5SE manual

    EPA: 21 city, 26 highway
    Actual: 18-19 city, 27-28 highway (calculated by hand -- trip computer reads high)

    I've got an 03 2.5S w 30k on it.

    My experience has been that the hwy mileage is good. I probably get around 28 to 30 and I've got a fairly heavy foot on the open road. Locally, I find that the car an be a real gas guzzler when I do alot of crawling. I lived in Queens until just a couple of weeks ago so I had many weeks when I would avg around 15 mph and found that the gas mileage would drop well below 20 mpg. If I average 30, the economy would far more acceptable. I probably got 23 - 25 mpg under those circumstances.

    I went through my mileage log spreadsheet and came up with some interesting stats. As I wrote above, my car is an '02 Altima 3.5SE with manual transmission. I do mostly city driving. My daily commute is currently 3.5 miles and takes me around 20 minutes, so it's pretty slow.

    Since I bought the car in December 2001, I have:
    Driven 35942 miles
    Purchased $3252.70 and 1731.7 gallons of gas

    My long-term average MPG is 20.8.
    My best MPG for a tank is 29.9 when we took a long road trip.
    My worst MPG for a tank is 13.9.
    My average fuel cost per mile is 9.0 cents/mile.

    Gas prices have ranged from $1.25/gal in December 2001 to $3.50/gallon in September 2005. Average price has been $1.88/gal.
  • I own a 2005 Altima 2.5S for about six months. I have the automatic trannie.

    MPG city about 22-23 mpg.

    MPG highway about 30.

    Best highway MPG was 33 on a long trip using a lot of cruise control.
  • I own a 99 altima, and it does better than other cars. Not as great as sentras or corollas, but it has more power also! On average I get about 350 miles or so to a full tank.

    I have a 2002 Alti 2.5S. It has 78K miles, auto transmission, Yokohama Touring tires. I only use Mobil 1 Synthetic since I purchased it new. I occasionally use Chevron Gas additive, BMW recommends it for their cars.

    I normally get between 30 and 34mpg on highway during warm weather when the air conditioning isn't on and going 70mph

    In winter I get as low as 27 and 28 mpg :cry: on the highway
    Last week due to the insane gas price jump I dropped my speed from 70mph and wouldn't go over 66mph. I stayed in the 64-65mph range and I got an amazing 37.5 MPG :) . I must admit I did drive behind a a few semis, a couple of days to kind of draft.

    I have gotten 34-35mpg on a tankful before but never literally 38MPG.
    Now that was an awesome feeling.

    My 2006 Altima 2.5 special edition is averaging 26.5 (heavy foot)m.p.g. My best mpg was 35.5 driving 55-62 mph on the ny state thruway from nj. This is based soley on the trip computer. When i got the car with 80miles on it. the computer read 19.5mpg with an average of 2mph.

    I have a 1997 Nissan Altima GXE (2.4l 4-cyl). I average 30-32mpg (computed manually). I drive mainly highways at around 75mph.

    I recently took a long trip that forced me to use country roads (no direct highway), with a max speed of 55mph. My mpg jumped to 39mpg!!

    I do use some low cost enhancements on it which I believe helped; Bosch Platinum +4 spark plugs (100,000mile life), K&N drop-in filter, touring tires (threadware rating 620).

    I've just started using synthetic oil, so hopefully the mpg figure could see a minor improvement.

    Had a 2.5S rental for a 220 mile trip, all highway with overall average (per GPS of 65 mpg). Freeway speeds were 70-80 mph and about 40 miles of 2 lane highway at 55-65. Averaged over 34 mpg (6.4 gal to fill up). I was very impressed.

    2002 Nissan Altima 3.5 SE (Manual transmission)
    w/ AEM cold-air intake

    City: 19 MPG
    HWY: 28 MPG

    my gas mileage has been great so far. I have been getting over 31.5+ mpg with the AC running on max based on the trip computer going 80-85 behind cars on the NYS thruway. When i'm the only car on the highway. I have to drive 75 with the AC off to get that kind of mileage with no people in the car. I drive over 550 miles on every tank. i usually get 28.2 mpg going the same 80-85 on the highway with no cars on the road with the AC on. I got my car in April and i now have 12,000 miles on it with not a single problem.

    I envy you guys' high numbers :confuse: My 2000 Altima (GXE 2.5L, 4-speed auto) fared far worse. Out of EPA city/highway ratings of 21/28, I got 22 to 23 mixed (35%/65%) when the car was new; city could easily fall to 18 mpg and highway trips would post 25 mpg. I have always driven conservatively, and rarely use A/C in this car.

    When this car becomes older, I now use even more aggressive conservation maneuvers to get 23 mpg city most (65%/35%) and 28 mpg highway. I'd love to learn some of your tricks. (Gotta admit that I wasn't very at tentative to tire pressure, but I would expect better mpg when the car was brand new.)

    ))"Gotta admit that I wasn't very at tentative to tire pressure, but I would expect better mpg when the car was brand new."((

    Nothing could be farther from the truth. A new engine is as tight as it'll ever be (until rebuilt again - if ever). The sliding/rotating parts have yet to achieve their ideal seating with their mating parts. To some degree this is also happening with the transmission. This period is traditionally referred to as "run-in" or "break-in", and though it's not nearly as involved a procedure as in previous times, it's still something that has to take place and will initially impact fuel economy. Engines don't hit their fuel economy stride until around 5,000 miles of accumulated mileage. Tire pressure will definitely affect fuel economy, too. Dealerships love to adjust tire pressure down below the factory recommended level prior to delivery to achieve a "boulevard" ride. A new tire will also lose some pressure initially until its bead fully seals against the wheel rim. Whatever its cause, lower pressure increases rolling resistance (bad for fuel economy), negatively impacts traction, and increases heat buildup within the tire (bad for tire life). Some owners actually prefer running their tire pressure several pounds more than the factory-recommended setting for further decreased rolling resistance and internal heat buildup. (But never increase the cold pressure beyond the maximum limit molded on the tire sidewall.)
  • Good point, ray_h1. (Note to self: Don't think you know physics; mechanics is what matters here :P ) Also nice pointer about "boulevard" ride. When I measured new, it was after break-in according to manual, i.e., 1,000 miles. With then commute of 20 miles/day, it took a while to get past 5,000 mile mark.
  • Just the other day i took a trip up north on the NYS thruway and got amazing gas mileage for the speed i was going. I average 32+mpg going 80-100(everybody was flying) M.P.H and on the way back averaged 35+ going 70-72. Iv'e already put 17,000 miles on the car and it's only 5 months old so the good gas mileage is a plus. I usually drive at least 500 miles on almost every tank. the most miles iv'e driven on a tank has been 615 miles.
  • I doubt I am the first to ask this question...
    Wife is buying a Honda Accord -
    I am buying a Pathfinder...
    What is the best deal on warranties for each?
    I am seeing lots of different options and my dealer is
    offering a few choices also, in different price ranges...

    Hi cryptoguy - welcome!

    This is an Altima Real World Mileage discussion, so the folks who can answer you probably aren't going to see your post here.

    What you want to do is check out the groups on the Accord and the Pathfinder. We also have a general discussion on Extended Warranties that may be helpful.

    2006 Altima 3.5 auto w/9000 miles on it.
    Took a trip and went 847 miles.
    Pretty much all highway at 60-75 MPH.
    The car got 29 MPG., not bad.

    Any data yet on mpg for the 2007 Altima - curious to see if it is really going to live up to the increased EPA estimates.
