CHATROOM: MPG 1st & 2nd Gen

[ahhbeebee]

Wow, that's incredible and I'm envious. I try my best too, never above 2500 RPM, and majority driving in a pretty sweet spot of 85 km/h, with engine revving at 1650 RPM.

I'm just over 4000 km now, no proper highway driving yet, although even in the city, I'm against traffic so go long (10km) on cruise, with no braking.

70% highway, 30% (half normal city, half brutal stop and go)

Tank 1: 10.17 L/100km 23.30 MPGTank 2: 9.60 L/100km 24.67 MPGTank 3: 8.59 L/100km 27.59 MPGTank 4: 9.03 L/100km 26.22 MPGTank 5: 8.36 L/100km 28.33 MPGTank 6: 8.21 L/100km 28.73 MPG

First few tanks I was also varying REV's for initial 'break-in'.

[gi'me]

I'm averaging 19.5 mpg around town. The gasoline vendors in my region only provide fuel that contains 10% added ethanol. This may be a factor for relatively low mpg.

[philipa_240sx]

You've got me... my last 2 tanks were 87 octane with a 10% Ethanol blend. Both tanks were mostly highway driving and I got about 8.1l/100km or 29mpg... some of my better fuel economy numbers. This on an SL FWD.

Ever since the 4000mi mark (after which point the engine was broken in) I have routinely averaged 8.3 l/100km or 28mpg and my worst was 24.4 mpg. I wouldn't say I'm a hypermiler, but I do pay attention to my driving habits and I do alot of highway and country driving with little traffic... not much stop and go.

It seems those with either AWD, lots of city driving, or a heavy foot are having trouble getting above 20mpg.

[kk]

Even i have been just getting in between 18.5 and 19.5 in city... it is considerably less

have been filling her with regular gas only...

and worse of all - have been driving like a grandma... max speed of 40mph and never above 2000RMB while

regards,Kumar.

Those mileage numbers jive with what I get. My strictly-city driving comes in at about 18 mpg. But I live in LA with stop lights every 1/4 mile. When I throw in a little highway driving I average about 22. Those who live in less congested cities get higher city mileage. It seems that the Rogue's mpg numbers come in higher than EPA estimates on the highway at around 30 (using U.S. gallons), and lower in the 'real' cities, ie. NY, Chicago, Denver, Atlanta, SF and LA, at about 18-20mpg. To me, it seems that the Rogue's CVT really likes to go at a steady speed. When it does it bestows upon the driver great mpg. Stop and go driving... not so much. That saddens me because I bought the Rogue because of the higher city EPA estimates (22).

Couple of things I've done to up the MPG a bit is to use Moble One synthetic oil. Does it give better MPG? Perhaps. Less friction should mean better mpg. I'll have a better sense on a long distance trip I'll be taking later this summer. I also up'ed the tire inflation to 43/lbs. That's higher than factory specs, but within the tire manufacturer's tolerances. That does help. Even if you don't go that high, make sure the tires are inflated to at least 40/lbs. I also clean and replace the air filter regularly. It's easy to do. LA is a dusty town in the summer. Check yours. If you see dark fabric, replace it. It will help your mileage.

You can read some of my other thoughts on the Rogue in my review on epinions.com. Just go to:

Leaving a comment there would be much appreciated. Thanks, and happy driving.

thanks richard for the reply...

i thought i was the only one getting such a low mileage.. because most of the other ppl are getting anywhere between 21 to 25 for city driving...

she is just 18 days old and have been able to do only 400 miles till now (100% city driving) so cant really change the oil. reg the tire pressure - its about 34-35 in all the tires, will try to inflate it till 40psi and will check if there is any significant difference...

main difference is with driving style - thats like below 2000 rpm all the time and slow acceleration....

[writeratwork]

One other thing that may help. Some of the posters on this board are from Canada. Lucky them. Their Rogue's have running lights. But up there they use those silly kms and Imperial gallons (which are 1.2 US gallons), vs. our correctly sized gallon, which is the kind that God had intended everyone to use. So clearly, Canada is a godless country, albeit with running lights. So when you see mpg of 34 hwy or 26 city, one has to make sure that that's not kilometers or oversized silly, godless gallons being used.

Posters are sometimes unaware that their numbers are being viewed across the boarders. I'm sure that many a Canadian reader has unknowingly read a US posting using US numbers and thought how horrible the Rogue's mileage is without realizing that our gallons are smaller making the mpg/gallon calculation seem lower than it should be.

That is your problem. The fuel mileage on a new Rogue will be a few mpg less than one that has been broken in. Give it until 3000mi and you should see better numbers. I saw a considerable jump in fuel economy after I put a few thousand on mine.

I'm sure that many a Canadian reader has unknowingly read a US posting using US numbers and thought how horrible the Rogue's mileage is without realizing that our gallons are smaller making the mpg/gallon calculation seem lower than it should be.

Most Canadians post l/100km and mpg so it's easy to check thier math. I have only found a few instances where someone did the conversion wrong and I have corrected many of them.

[ahhbeebee]

Okay, Philip, I reread your last post and noticed 8.1 L/100km. I think there must have been a typo in the previous post cuz I thought you worte 6.1 !!

[philipa_240sx]

Nope, go back a page and my previous figure was 6.9l/100km or 34 mpg. I drive about 800km a week so my mileage figures are posted very frequently.

[gregoris]

Ok guys I figured out my Rogues Gas woes.

You have to drive it like you are in a procession to a funeral.If you do this you will get good gas mileage.

I found once I broke in the motor to around 7,000 kms (I live in Canada, sorry my US cousins), the mileage improved. (Got the oil changed too).

In any case like someone said earlier on if you drive it like a sports car you will get the mileage of a sports car. I'm getting about 7.9 to 8.2 ltrs/100 kms on a SL FWD model, driving about 50/50. Speed matters. If I go the posted speed limit around 90 kms/hr or 55 mph, I get the epa ratings. This really sucks! but its the sacrifice you pay for good mileage. When my wife (lead foot)drives the gas mileage drops easily by .5 litres/100 km.

So it's all about how you drive it and how gingerly you accelerate.

Thanks for everyone's input.

[ahhbeebee]

Yeah, thats' the post I meant. Even then 6.9L/100km. That's insanely good. I'll be taking the car out for a road trip this week so I'll see what numbers I get with real highway driving, instead of these in-city freeways.

[philipa_240sx]

The 6.9 l/100km or 34 mpg was due to where I was driving. All country roads at 90km/h or about 55mph and less and very few stop signs.

[writeratwork]

OT: Just joking around with the Canadian vs. US postings, though it's easy to make the conversion mistake. But I am very jealous that the Canadian versions have running lights. What's up with that? A locking gas cap would be a huge plus as well. Maybe they'll give us that option in the US someday.

Re: the break-in period. I actually found that the best mileage I got was the day I drove the car home from the dealership. After that it's been down, maybe 2 mpg overall. And I drive it like a kitten walking on cotton balls. After about the first 800/miles it's been steady, and I've got about 7.5k on it now. So like people, each car has it's own personality.

The upside is that the Rogue seems to be getting what the sticker says on the highway: 27-32, and 18-24 city. In the "old" days, if the sticker said 27 highway, you would expect 24 if you were lucky. Nowadays, with the new EPA testing, when it says 27 highway—at least in the Rogue's case—one will often get 30. That alone makes me very happy.

=But I am very jealous that the Canadian versions have running lights. What's up with that?

Daytime running lights have been mandatory in Canada since Dec 1989. I guess Nissan USA figured they didn't need them.

Staying On Topic:

Latest figure:

8.0l/100km or 29.4mpg 80% highway at 90-110km/h (55-70mph), 20% city at 60km/h (30mph). I got 700km or 434mi on a full tank.

[Gzhou8888]

Mine is SL AWD. 70Km round way to work. 70% Highway Driving (Traffic most the time), 30% Local. (Downtown Toronto Area). Just reached 2000Km. My Avea reading is 9.5L/100Km or 24.7mpg

l/100km to US mpg conversion:

235 / (l/100km) = US mpg

[kk]

hey guys had never seen any number above "20"mpg, in the computer reading - had been doing 100% city driving...for last 3 weeks!

today had gone for a short highway trip and computer showed max "32.6" throughout the way!!

today i feel happy!!

[worldbikr]

Now that I've switched to synthetic I've recently acheived about 29-30mpg on the last several tanks. 22K miles. mostly 45-70mph hiway/interstate cruising. no stop and go.

[NeverOutofTune]

Rogue '08 AWD SL60% Highway / 40% CityLocated in Columbus, Ohio, USA, level terrain.

Use cruise control as much as possible, easy on the pedal, one person most of the time, no other loads.

Starting in June, the air conditioner was used a lot which appears to lowered my mileage by 1 to 2 miles per gallon.

Happy with my results.

Thats right on par with what i've been getting with the exception that since it's gotten warmer i've been getting over 27mpg almost every tank using 89octane 10% ethanol blend. 80%hwy driving @ 60mph. Pleasantly suprised!

[partsandaccessoryguy]

My wife gets 23/31.3 mpg with her SL 2WD

[ahhbeebee]

As Philip has previously posted, the Rogue can either be great on fuel, or 'normal/poor' depending on your driving style and engine revs.

I just got back from a trip to Glacier NP in Montana with 2 very different results on fuel mileage depending on the driving style.

My first tank, where the highways were smaller 90-105 km/h (roughly 60 mph) - I got an astonishing 34 mpg (7.0 L/100km), and this included several trips up and down the mountain towards Logan's pass. Engine rev's were pretty much always below 2000 RPM, A/C used 35% of the time. (Still haven't topped the 6.9 L/100km record though).

However, when I got out to other part of the state, where I was routinely doing 120 km/h (80 mph), my fuel economy dropped to 25.7 mpg (9.2 L/100km), with A/C use about 35% of the time. Engine was revving at about 2400 RPM, but I was passing often, and even got the car up to 5000 RPM in one case. I also had one tank at my typical 28 mpg on the highway, cruising 110 km/h, engine at about 2200-2300 RPM.

Although I wouldn't rate 25.7 mpg as necessarily poor, it is actually less than the 28 mpg I average in the city (hypermiling). So, for those trying to get better mileage, it takes a lot of patience, and discipline not to open up the engine past about 2000 RPM.

good luck with your fuel saving!

[philipa_240sx]

Hey, I'll take the 28mpg I average over my '87 Pathfinder which was a gas hog at 16mpg... on the highway! Don't ask about city mileage...

[ahhbeebee]

Yeah, I really shouldn't be complaining, I was just a little surprised that some of my highway mileage was worse than what I get in the city. I guess gunning it on the highway is still gunning it . I'm just amazed how much of a difference a few hundred RPMs extra makes on the mileage.

[Gzhou8888]

Mine is SL AWD. 70Km round way to work. 70% Highway Driving (Traffic most the time), 30% Local. (Downtown Toronto Area). Just reached 2500Km. My Avea reading is 9.3L/100Km, Manully calculated is 8.9L/100KM

[roguetoad]

I'm just amazed how much of a difference a few hundred RPMs extra makes on the mileage.

Makes all the difference in the world when coupled with how/when/where you apply those RPMs.

Our overall avg is almost 33

1,700 miles TT, between 4,600 and 7,000 MSL altitude, AC on 50%, one person in car, just a smidge of paddling, regular fuel, light cargo, nothing on the top, 80% hwy (45-65), semi-synthetic oil (Motorcraft).

Driving like a kitten may not always be the best way to get better mileage. No, you don't want to be Don Garlits, but if you combine easy and smooth with putting the engine in the part of the powerband where it's working the best, you'll do better. The OB computer doesn't always do that.

I noticed that keeping the car at 1500rpm when accelerating proves to give a quite impressive acceleration for the low rpms.I still have to install the scangauge to see if the numbers are good too, but the impression is there.

Do you have more information about this more efficient powerband?

[jk47]

Just filled up my tank for the first time (the dealer gave me a full tank when I bought the car last week)

Here are my results:Miles: 350.5Gallons: 15.7 - with one tick still left on the gage!MPG: 22.2

My ratio is probably about 70% city, 30% highway. About 25% A/C use, trying to keep rpm's under 2.5k.

[philipa_240sx]

Latest tank:

7.9l/100km or 29.6mpg20% city @ 35mph50% secondary roads @ 55mph30% highway @ 65mph

I keep it below 2000rpm even when accelerating. Heavy acceleration in short bursts just to merge onto the highway.
