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???

just finished driving RT to Washington DC along I-95 about 300 miles. most of the trip, caught the "draft" of trucks. would not recommend this to everyone unless you have nerves of steel, quick reactions and someone to watch for state troopers to make sure that you don't get caught tailgating. but averaged about 30-34 mpg going about 70 mph. (don't know how truckers feel about this...having a little Rogue trailing them closely).

Well, truckers don't like tailgaters at all. If I were you I would stay away from truck stops. Seriously this is a very dangerous practice.

yeah, no kidding - I think that those same truck stops might also have a different definition of 'justifiable homicide'
'drafting' (to be truly effective) requires that one follow any vehicle much too closely to be safe! They can and do write tickets for this kind of thing?

In addition to that little Rogue being a danger and an annoyance, any fuel savings that you might get out of it is coming at the expense of the trucker. It's tough enough for those guys to stay in business without having to shell out extra cash from their own pockets just so you can feel good about cutting your own fuel costs. Moreover, the rest of us end up paying more for the products they deliver. There is no free lunch.

I have not heard of this. The big rig is going to generate the suction behind the vehicle regardless - the same suction with a drafter as without. There is no magical connection back to the big rig, is there? Where did you read this?
 
My understanding is that the drafter is entering into the suction zone where the air came off the big rig. But that zone is always present...
 
The truck drivers don't like it because people follow too closely, and the drivers can't see them in the mirrors.

I'm afraid not. Flow patterns are changed and the truck has to do extra work. The notion of a perpetual motion machine still doesn't fly.
