#56 of 88 First numbers for 2.0 S by backy

Apr 10, 2010 (1:37 pm)

Just leased a 2.0 S. I was impressed with how low the revs were during the test drive, and I had no problem keeping them low since I typically drive with a light foot on the gas. I figured with revs like 1800 RPMs at 60 mph, fuel economy should be very good. So I got the car (got a great deal on the lease). On the way home, on suburban streets and freeways, I averaged 38.5 mpg if the computer can be believed. I noticed when the computer was in real-time mode, I was getting 40s-50s mpg when cruising around 40 mph on level ground, and RPMs were super low, around 1200. So I think it's very possible to get high FE in this car. I'll report again when I have driven it a bit.

#57 of 88 First tank report by backy

Apr 23, 2010 (3:21 pm)

Just filled up the tank on my 2.0S for the first time. Got 32.4 mpg on the tank, by computer. I don't know how full the dealer filled it, so I can't go by the pump this time. I was happy with the mpg, since it was all in-town, a mix of city and suburban driving and urban freeway driving. I used a light foot most of the time. The car is so quiet at cruise!
 
When I switch to instantaneous mode, I can see the sweet spot for the car is around 55 mph; there the car does close to 50 mpg on level ground.

#58 of 88 Second tank report by backy

May 15, 2010 (6:15 pm)

Got 32.6 mpg on the second tank per the computer, very close to the first tank, still all in-city driving with mix of freeway and city streets. Manual calculation was 31.0 mpg, but I filled at a different station than the last fillup. If I can average 32-33 mpg consistently for in-town driving I'll be very happy with that. For comparison, I averaged about 30 mpg in-town on a 1997 Sentra 5-speed with a 1.6L, 115 hp engine. So I'm doing better with an automatic car that's more powerful and a lot bigger and heavier.

#59 of 88 2008 Sentra Spec-V by dfmike

May 18, 2010 (12:21 pm)

I bought a 2008 Sentra SE-R SpecV new to replace a '95 Taurus I used to drive (which got around 22mpg combined, maybe 23 if I was careful). It is rated at 21/29. On long trips I have averaged around 30-31, but my weekly average at home is more like 28 (my commute is probably 2/3 highway speed, 70ish for me). I do write down my mileage and gallons at fuel stops, and over the 33,000 miles I've put on the car so far, I've averaged exactly 28mpg. The car's calculator is usually 1mpg optimistic, either that or the pump is slightly overestimating how many gallons it is giving me...
 
My first set of tires (Conti Sport 2's) only lasted 27,000 miles thanks to some enthusiastic driving. Not that I mind much, since the fuel savings just about covered it... Basically I'm having a lot more fun in a car the same size and weight, but handles far better, has 60 more hp, and still gets 25% better mpg.

Don't know if anyone has experienced this but I have a 2008 Sentra and get better city mileage than I do hwy. If I avg 35-50 mph hitting lights, stop signs, etc I get around 35mpg. On the hwy if I stay right at 70 mph I get between 32-33 mpg. If I go faster than 70 my mpg go down drastically. Please reply if you have this problem.

I have noticed on my 2010 w/CVT the suburban mpg e.g. around 40-45 mph with few stops is VERY good, mid-to-upper 30s. The longest highway trip I've taken was 100 miles, 50 each way, and that was at speeds only up to 65 mph, and I got about 37 mpg on that. I could see the mpg going down above 70 mph, as that would be consistent with every other car I've owned. The sweet spot for most cars I've driven seems to be around 50-60 mph. So I don't consider the mpg going down above 70 a "problem". Fortunately for me, there is no road within 1000 miles of me where above 70 is legal.

I'm getting about the same in my 2008. You'd think that the CVT would adjust a little better on the highway - not run at 1800 rpm on flat roads.

Its not the cars problem. It's your driving that is affecting the MPG past 70, Vehichles are at their optimum fuel efficiency in the 55-60mph range.
 
For example if I wanted to push my 05 Nissan to the extreme in MPG numbers (40mpg Hwy 38mpg city) i'd use hypermiling techniques. Sure I'd anger every other driver out there with slow starts from stoplights and slow merging on the highway but I'd save enough on gas to make it through 4$ a gallon.
 
Currently I'm sitting at about 30mpg combined without doing hypermiling.

#64 of 88 Up to 35.0 mpg by backy

May 29, 2010 (12:19 pm)

Just filled up the 2010 2.0S CVT, and on my last tank-and-a-half (I put in 6.6 gallons earlier, couldn't pass up a great price) I averaged 35.0 mpg by computer, and 33 mpg by calculation (but I filled at two different stations this time). This is significantly better than any other tank to date, even though I used the AC about half the time and didn't use it hardly at all on the first two tankfuls. I did do more miles on urban freeways this time--probably 80-85% this time around. All the freeways in my town have a maximum speed of 65 mph, although yesterday I went for a 50-mile trip and got up to 70 for awhile because I was outside of town.
 
About half-way through this run, I was at about 37 mpg. Then use of AC, more city streets, and more stop-and-go (construction etc.) took their toll. I'm happy though with 35 mpg, given the EPA for highway driving is 34 and I was driving mostly in town.
 
The car is very sensitive mpg-wise to pedal pressure. Keep a light touch on the pedal, and you can get very good fuel economy. But use all 140 horses, and the mpg meter will sag pretty fast. That is what I saw the few times I decided to see what kind of pep the car has.

I'd like to correct my last post. My 2008 runs at 2200 rpm at 70 mph on flat roads. On hills I can understand 2200 rpm but I don't even hit 2200 rpm starting from a dead stop. That's why I get better mileage in city (not much stop and go) driving.
Driving like there's an egg on the gas pedal helps alot!
