That's interesting. My 2.0 CVT runs at about 2000 rpm at 70 mph, on flat roads. I wonder what could account for the difference, i.e. was there some change made between 2008 and 2010?
#67 of 91 2000 miles, 34.1 mpg
Jun 26, 2010 (4:14 pm)
Just filled up and got 34.1 mpg over the last 22.5 gallons (did a partial fill awhile back). I was at 34.5 until the last few days, then did a lot of driving on city streets which brought the average down a bit. Still pretty good though. I didn't have any trips over 25 miles this time, and had the AC on more than the last reading--starting to get hot and humid. Car is now just under 2000 miles.

Now close to 3000 miles. Did one fill at 34.3 mpg, usual around-town stuff like most tankfuls. Then I took the car on its first long trip, a 530-mile round trip in one day, most of it around 65-70 mph but with some slowdowns for construction and accidents, and a little in-town driving on both ends. After 2 hours I saw 40.2 mpg on the meter and had dreams of getting over 40 for the trip. Then I hit some construction and accidents, and that plus the in-town driving brought the final tank trip average to 37.8. Had the A/C on all the time--got to 90 F that day.
#69 of 91 2008 Nissan Sentra 2.0S real world MPG
Sep 14, 2010 (10:31 am)
Total miles driven 58000 miles, 80% Highway miles, Air conditioning uses 20% of the time. Drives 65 miles/hr speed.
Cruise control - very rare and it reduces the fuel efficiency.
Car Trip Computer reading - don't trust that reading, it reads 3 -5 miles more than actual reading.
I do use scan gauge and drive behind the truck occasionally.
I do reset the trip computer and odometer every time fill the tank, always filled the tank in full. The actual mileage is from 30 to 34 miles/ gallon - best tank full.
My Opinion - this is not a fuel efficient car and not suitable for hypermiling either. I do drive Camry 1997 and 2007 both of them gives better mileage than Sentra.

30 mpg with 80% highway at 65 mph seems very low for the 2.0. Do you have the CVT or stick?
I have found that high FE on the Sentra requires a very light foot. I notice when my wife drives our 2010 Sentra (which is not too often), FE drops greatly (she has a lead foot). For example, she'll struggle to get low 20s in town while I easily get over 30. I hate it when she takes out my car, because I'll be doing fine on a tank, between 34-35 mpg usually (it's at 36.2 on current tank), and she'll drive it a bit and it's down below 30! When I have intentionally used a heavier foot (or just feel like zipping around a bit), FE drops off. Based on my experience, I think upper 30s, even close to 40, is possible under the conditions in which you drive, if your highway miles don't involve much traffic, but you'll have to work for it and resist all temptations to unleash the 140 horses. If that is too much work... oh well, 34 mpg is the EPA highway rating for the car.

#72 of 91 2010 Sentra SR MPG Problem
Feb 18, 2011 (1:42 pm)
Hello Everyone, I'm new to the forums, but I was wondering if anyone could offer any insight to a problem I'm having. I purchased a 2010 Sentra SR a year ago and have had consistent mpg problems. From the get go, I experienced 28mpg with ~75% highway on 65 and 70 speed limit highways (i normally never go above 5 over and use cruise control as much as possible). Since the winter hit, I've seen a drop in my mpg to 25-26. However, I have a new job that requires me to travel an hour and 15 minutes one way... 98% highway... and I don't use the car for much else because the mpg has been so depressing (i also have a corolla that gets ~34mpg constantly, so I use it for errands and such, but my wife also uses it for work... she likes it better ~sigh~). The speed limit is 70 the whole way. I hit 75 and put on cruise control and hardly need to speed up. I use the same gas all the time (Shell), mostly from the same station. I finally got frustrated enough after a calculated mpg of 25.3 that I went to the dealership I made the purchase from. They ran a fuel alpha test which tests the fuel to oxygen ratio being used and said that it fell within normal parameters (....sure it did) and that there was nothing they could do. They did suggest trying a different gas, but I don't think that will offer a great difference, or maybe that's naive. Anyway, I honestly do not think this is normal and was wondering if anyone had any information I'm missing or could think of something I could do to improve the mpg. Thanks!
#73 of 91 Sentra 2010 Mileage Problem
Feb 18, 2011 (6:01 pm)
I have the same problem. Mine is Sentra 2010 2.0S with 5400 miles.
My city MPG is 17.5 although the manual says around 32.
I went to dealership and they said I better wait until I get 9000 miles.

You have the 2.0L and CVT, yes? I have a 2010 2.0S, and on the highway with cruise, flat or gently rolling terrain, 70-75 mph I get in mid-30s in winter to upper 30s in ideal conditions. In the city, with some urban freeway driving, I was getting low 30s until winter hit, and it's been a bad one in Minnesota. So I do well now to get mid-to-upper 20s, depending on mix of city and urban freeway driving.
But if you are getting only 25 mpg at a steady 75 mph, no stops, not much headwind, properly inflated tires, that is low. Have you tried resetting the average mpg readout when you start a trip where you will maintain a steady speed and w/o much headwind? It would be interesting to see what the mpg is for such a trip. Also it would be interesting to know what your instantaneous mpg readout says when you are moving along at a steady 75 mph, with cruise on, on level ground. I'd be real surprised if it wasn't in the mid-30s mpg.
#75 of 91 Trip report
Mar 08, 2011 (7:51 pm)
I just did a 550-mile roundtrip from the Twin Cities to Madison, over two days. The car was a 2011 2.0S with about 2500 miles on it--a rental. The funny thing was, it was EXACTLY like my Sentra, even the color, except mine's a 2010. Also the rental had a spoiler. To Madison I got 36.9 mpg--some snow showers, temp around 30 F, light wind. Doing in-town driving for a day brought that down to 36.2. But by the end of the trip, the average was 37.3 mpg--meaning I averaged over 38 mpg on the return. I was surprised by that because I was going into pretty strong (20-30 mph) headwinds most of the way. Temp was about 40 on the way back. Average speed for the entire trip was 60 mph, including in-town driving and a few stops. On the freeway I stayed around 68 mph (65 limit), and had the cruise on.
The numbers are consistent with my 2.0S under similar conditions... not surprising, as they are the same car.
P.S. Originally I was given a Yaris. I begged for something else (it didn't even have cruise) and got the Sentra. At least I knew what to expect with it.
