although your FE should improve very slightly as the engine 'loosens up' I would tell you that 23 mpg overall in the City is quite good.

That is quite interesting. This is actually the first time I've seen any evidence that the Rogue gets better fuel mileage than the Forester. I agree that, with the CVT (vs. the 4AT), the Rogue should get better fuel mileage than the Forester. I can tell you that it does seem to accelerate better and shifts (with the paddles) very quickly and crisply. The transmission is probably the Forester's weak point. Thanks.

an aside - it is that 'electronically controlled/ learning ' Forester tranny that he had to take back to the dealer to get reprogrammed - the car was developing a helluva hesitation problem. The TSB did work though, haven't heard any further complaints.

2008 Nissan Rogue gas mileage problem

I bought a 2008 Rogue 3 days ago in Colorado and the first 400 miles I got 25-26 mpg. Then I filled up in KS and it plummeted to 13-15 mpg. At 700 miles I filled up again and it still only got 13-15 mpg for the next 80 miles driven. Everyone's reviews I read about says they get from 23-28 mpg. I drive 17,000 miles per year with 2/3 of those miles on the highway. I can't take a hit on my gas budget like this. Any ideas on what is wrong and what I need to do about it? Thanks.

I bought a 2008 Rogue SL AWD 5 days ago in Montreal and for the first 900 miles I got 25-26 mpg (US). Same hils, about 95% highway at 70 highway speeds
A/C on
cruise control used about 50% of the trip

That is perplexing. You don't have the OD turned off do you? Or does yours have that feature? Even that should not account for the drop you're seeing. Maybe the difference in fuel (are you running 10% ethanol?), but again, you should not see that big of a reduction. I'd suggest you check with your dealer, but previous posts have led me to believe that would be futile. Go back through the string and you'll see one or two posts similar to yours (although not so extreme). My personal conjecture is that there's a 'glitch' in the CVT and/or fuel management programming. But, since it's evidently not throwing a code or lighting a light on your dash, the dealers aren't doing anything about it. There is a sequence for resetting the computer, but I'm not sure what it is. It's something obtuse like, disconnect the battery and turn the key to the 'on' position 6 times. And I don't know what other effects that might have, so not sure I would recommend it without talking to someone more in-the-know than I am. Still, it won't hurt to register your complaint. If enough people do so, maybe Nissan will do something about it.
Quite frankly, posts like these are one reason why I've chosen to focus on the Forester. While there is some disparity in mileage returns on that thread, no one has reported anything like this or the issues one or two other have seen. Everyone over there is getting 20 to low 30s, depending on driving style, speed, type of traffic, terrain and road conditions - which is within the realm of reason. Aggressive stop and go city traffic versus steady state highway cruising makes a big difference in these little 4 cylinders.
The only decision for me now is whether to go with Forester or go with a mid-size sedan - the Malibu LTZ. The Bu does not offer the utility or AWD of the small SUV, but it does offer much better mpg (33 mpg highway with the 4 cyl, 6AT) and even better creature comforts than either the Rogue SL or Forester Limited. I even like it better than the Altima 2.5 SL and the Altima is a very nice car.
So, I probably won't hang around this thread much longer. But I do appreciate all the good information I've gathered.
Good luck to you.

No, the overdrive is not turned off. I have driven it mostly highway for another 75 miles and now it is registering 20 mpg. That is much better than what I was getting, but I am still hoping to get back to the 25 mpg I had during the first 400 miles. As far as the rest of it goes, I think my 2.5 SL AWD Rogue has nearly all of the amenities my 2006 Altima 3.5 SL had. The one thing I am finding I really miss, though is no automatic headlights that turn off or climate control AC. The leather seats are very nice and are heated like the Altima. The biggest difference is my Altima got 30+ mpg on the highway and combined mpg was around 24. I really detest the break in period on a new vehicle. The other thing is, my husband has a tendency to go 80 mph on the highway, which coupled with crosswind probably kept me from getting very good mpg on the last half of my trip (I am guessing). I am sure he won't slow it down without an argument. He is also having a little trouble getting used to the CVT transmission, as he always loved to shift the Altima himself, although it was an automatic. Anyway, right now it seems there isn't any consistency to the mpg, so I will just have to keep an eye on it. I did register a complaint with Nissan, however. Thanks for your response, Phil.

I too have a bit of a heavy foot, so I've been taking that into consideration as I read these posts. The Rogue SL I drove had paddle shifters on the steering wheel, which would force the CVT to emulate a 6 speed. Interestingly, I noticed that when I shifted it out of that mode into full automatic at highway speed, it would actually shift to an even higher ratio than the "6th" gear of the manual mode, which means you need to be in "D" when crusing on the highway to get the best mileage. I will say this about the CVT in the Nissan, be it Rogue or Altima, it feels more like a 'normal' automatic than the unit Ford puts in the Escape/Mariner twins. I was also disappointed that they had no climate control. In fact, I would really prefer a dual zone. I have it in my truck; I'd think these vehicles would have that feature. Good luck with the mileage thing.

apparently true - have observed 70 mph to be at approx 2200 rpm if the tranny is left in 'D' BUT over 2500 rpm in '6th' a significant difference that logically would effect FE. The CVT while it does take some getting used to, is phenomenally smooth in the Rogueand cetainly 'smoother' than any AT I've ever had in any car - really don't understand why anybody would want to paddle shift it - after all it is no 'sports car' and overiding the computer gear 'selections' hurts FE???
