Nissan Sentra Real World MPG

patpat Posts: 10,421
What sort of mileage are you getting in your Sentra? Report the numbers here.


  • I am getting abt 30.5 mpg (average), as per the trip comouter, mostly highway driving. 80% highway and 20% city driving. I have seen highway numbers go as high as 36 mpg but since city driving numbers are not good, the average does not go above 30.5 mpg.
  • I have a 2002 spec-v. 90% of my driving is city and the speed limit where I do most of my driving is 30mph so its not like I can drive it hard. Every time I fill the tank I calculate my fuel economy. I'm consistantly getting 17mpg (when the whole tank is used in the city). The best I've seen on the highway is 26mpg. I don't drive the car hard, my air filter is clean, my spark plugs are new and my tires have the proper amount of air in them. I don't want to take it to a dealership until I know I've tried everything I can. Is this normal or a problem??
  • Hi
    I am also having the same problem. Does anyone has some clues?
  • My mpg readings for my Spec V on the gauge stay around 23-24 mpg.
  • Hi James,
    My car is a Nissan sentra XE 2001. I am getting very low gas mileage. I went to mechanic, they found problem with O2 sensor, then they called Nissan, and found that it was due to problem on camsensor which was on a recall. Then nissan fixed it for free, then my mechanic checked the O2 sensor and seemed OK, but still I am getting low gas mileage, practically same as before. The mechanic told me there was no problem in the car. I am getting 17 MPG during winter.
    But other are getting around 25 MPG during this time of the year. Any expert comment would be appreciated
  • If you haven't already I would suggest trying a K&N performance air filter. When my Grand Am had the stock filter in it, it was like the car was scruggling to accelerate and after I installed the K&N the car was much more responsive than before. I may also suggest putting on a inexpensive semi larger catback type exhaust pipe because those tailpipes on the "economy" Sentras look too small and maybe hurt gas mileage, the easier the engine breathes the less stress on it in my opinion. Those stock air filters are crap with a capital C, it is like trying to breathe through a straw.

    none of you guys are really having a problem, if you have the 2.5 litre engine that is. The new epa sticker for a 2002 spec v is 19/26 which sounds exactly like the range you are getting. Its a performance engine, not a hybrid.
  • No mnan, mine is 1.8L engine!!!
    I have another question, hot air comes out of the vents even when the fan is not truned on. if I put the temp knob to cold region (blue), then cool air comes out. what is it? is it that the heater or AC is truned on even when I dont turn them on!!! all strange things happening. I had a subaru car, such thing never happened.
  • That means the vent is simply redirected. if you leave the fan off while leaving it on cold outside cold air comes in. My 2.5L Spec V engine gets 23/29 according to specs but I probably get at least 30 mpg because I can go from here to Virginia Beach and back on one tank still having plenty left over.

    Thanks for the input! Just curious, where is "here"? :)
  • Richmond. 120 miles away from Va Beach. 240 mile round trip with gas to spare.

    First tank: 31.48 MPG, mostly city (80%).

    Computer reports 52.2 MPG at 38 MPH, close to 47 MPG at 50 miles per hour.

    On my daily commute the typical MPG is 38 (50% city, 50% highway).

    I'm hoping these numbers will get even better after a few 1000 miles and brake in.

    The last fill up yesterday yielded an MPG of 39.1.

    This is for a commute of 40 miles each way, 50% highway, 50% city, most of it stop and go traffic.

    I think I am getting the hang of it, treating the gas pedal as if there was an egg under it.

    According to the trip computer, today my average is exceeding 41 MPG by a little bit. I hope there are no accidents on the way back as that would mess up my average.

    Anyone who can beat me? I love a challenge!
  • Keep up the mileage
  • pulgopulgo Posts: 400
    I am going on a long vacation trip on Sunday (BC-WA-OR-CA and back).

    I will report the MPG numbers in a couple of weeks.

    Thanks rennie4. It remains to be seen what winter will do to the mileage. My Sentra comes with a block heater so when it gets cold I will plug the car in for an hour or so every morning (on a timer).

    i get 22-26, for the most part in my 2002 SE-R. i drove 2700+ from los angeles, california to phildelphia, pennsylvania and got 27-30. it was pretty sweet. unfortunately, i dont drive like that every day! but i do love my sentra. :shades:
  • My '07 has 250 miles on the ODO and I am getting an average of 26. That also is almost entirely city driving to work. I only have maybe 10 miles of freeway driving so far.
  • pulgopulgo Posts: 400
    Well, I am back from my trip from BC to WA, OR and CA.

    MPG for the whole trip was 36.19. Fill ups varied from 32 to 41.5. 41.5 was for over 350 miles of highway, at steady speeds of 60 to 70 MPH.

    Can't complain!

    Yesterday I filled up after a week of commuting to work. Lot's of stop and go, 2 days where the trip to and from work took almost 2 hours each way (40 miles distance), "normally" it is only 70 minutes.

    50% of the trip is highway with speeds of 60 to 70 MPH. The rest is stop and go.

    The number: 40.26 MPG

    I am a happy camper as this number is almost matching what I was achieving with my previous 2001 Toyota Echo.

    Considering this is a much heavier and powerful car I could not be more pleased.

    Once I switch over to 0W-30 synthetic oil (now using the last few quarts I had of Amsoil 10W-30 synthetic) the mileage should improve a tiny bit. It will probably be compensated by the lower temperatures.

    This week I am purchasing a complete set of winter tires and wheels and that will mess up my mileage for sure. Winter tires have higher rolling resistance than summer tires. Oh well, safety is more important to me and although it does not snow much in this area I like to be prepared.

    It does rain a lot and winter tires should help in this kind of weather.

    I don't understand how you get those numbers...

    We had 08 Sentra SL for about 3 month and already have 3k miles on it. The car is great, other then mpg. I average about 280 miles before I need to fill up again with 50/50 city/hwy driving. This seems not that great considering our previous 03 Mazda 6 with 17 gallon tank got over 300 miles and with 170 hp engine. Also, our SUV gets 200 miles on the same 15 gallon tank. What's the deal here? Are you guys driving down the hill constantly?
  • Your driving makes all the difference in the world.
    When I am tired of work and want to be home soon, my mileage drops dramatically. Why? Because a follow cars in front of me closer, I accelerate more suddenly and I have to break more. I also tend to exceed the speed limit (62 MPH) quite a bit. On those days I average around 33 MPG (US gallons).
    When I listen to my CD's or am busy with my HAM radio I tend to leave more room to other cars and I keep my speed around 60 MPH. Those more relaxed days I get between 36 to 38 MPG, now that the weather is warmer the occasional 40 MPG.
    My commute is 40 miles each way and I am always in stop and go traffic for 45 minutes or more every day.
    I have to drove to Vancouver from the Fraser Valley on Highway 1 and that means crossing the infamous Port Mann Bridge. For 5 or 6 miles before that bridge the traffic comes to a crawl and the typical speed is may be 10 MPH, sometimes less.
    In the afternoons the same game again, just the other way. The last 20 miles home is a steady 60 MPH (Usually).

    My tricks to save are:
    Tire pressure: 38 PSI
    Engine oil: 0W30 Synthetic (Mobil 1 or Amsoil)
    No speeds higher that 70 MPH. No jackrabbit starts and no sudden braking. When accelerating I do not exceed 2500 RPM. I am NOT a rolling obstacle on the road, I just move at the same speed as everybody else. I DO have a SCANGAUGE and I do everything I can to drive more efficiently. I do not have an ego as I don't need to be the first arriving at the next red light.

    As noted earlier in the discussion, the Spec V engine is performance oriented. I live in the city during the work week and have a 69 mile run home on the weekends. I'm averaging around 24 mpg overall. I've gotten as high as 28 mpg on mostly freeway cruising. City driving is a different story. 19 - 22 as the EPA sticker says. Not out of parameters but ..... I've been experimenting with watered-down hypermiling (low up-shifts, better awareness of traffic, easier breaking) and I'm getting better results in the city. Sometimes, you just have to enjoy the car though :-) ...

    Anyone tried to run the Spec V on regular fuel? I've been searching for information that will say "no way" or "its okay"...
  • These past 5 days I have stayed at or under 58 MPH on my commute to work. I decided not to change lanes at every other highway onramp and not to try to be the first at the next stoplight. Driving like there is an egg under the gas pedal over the last 392 miles i got 42.77 MPG (40% city and 60% highway).

    I keep RPM's under 2000, even when starting from a dead stop. Tire pressure is kept at 40 PSI.

    I am not coasting or doing things hypermilers do and I'm hoping not to aggravate too many fellow drivers.
  • :lemon: I tried all those tricks but still avg. 20 mpg and only get 24 on highway.
  • I have done it in my maxima but mpg went down, didn't feel any different though.
  • If you only get 24 on the highway, especially if you use cruise control and do not exceed 75 MPH, then something is seriously wrong with your car. I would rent another identical Sentra for a day, making sure the tank is full. Then I would take a highway trip of at least 200 miles and fill up again. If you do not achieve 30 MPG or more, it is you, not the car.

    Where do you live? Is it very hot and do you use AC all the time? Is the car equipped with a roof rack? Low tire pressure?

    With approx. 8,000 miles, I average between 24-25.5 in city, and on a trip to Tucson from Phoenix, I averaged 38.2 mpg. That's up quite a bit from when I took my first trip to LA from Phoenix where I barely averaged 30 mpg highway. Of course, this trip, I keep my speed at 65 and that seems to make the different.

    HM are you confusing imperial gallons with US gallons?

    40 miles/imp gallon = 33.3 miles/US gallon.
