CHATROOM: MPG 1st & 2nd Gen

[YGBSM F-4G]

I would have to say that 75-80 mph is a big reason for not getting above 24mpg. After 70 mph, your mpg really starts to go down. I used to have a heavy foot but have gotten used to doing 65 since I noticed how much better my mileage is.

I'm averaging almost 27 mpg with my AWD Rogue and on my fourth tank now.

[babbot]

I know that going 75+ will hurt my mileage, but part of my disappointment is that I'm just doing about 2mpg better with my Rogue than I did with my Murano (6 cyl, 245 hp) in the same driving.

I thought I'd get a much more noticeable improvement (which is the main reason I made the switch).

[Rouge660]

I'm driving the SL AWD. Its got 150 miles to the car.

The first 100 miles, I averaged 15.7 mpg

I reseted to zero, and the next 50 miles, I've only been getting 14.5 mpg

This is really frustrating me. Mixed usage of 25-35% highway and 65-75% city.

Anyone else experienced this? Thoughts? What should I do?

Does the type of gas matters? I'm still using what the dealer had in the tank. What type of gas should be put in?

[Derango]

The MPG calculation on the computer is notoriously inaccurate.

You're better off doing the old school calculation by hand after you first tank of gas to see what you're getting.

[exeunt]

Second tank, filled it up at around half way..

8.7 gallons, 161.4 miles = 18.55mpg

Although this is probably because I've been warming the car up in the morning for 5-10 mins before leaving. Yes I hate the cold.

I live in Brooklyn NY and have had the Roque for a week and a half When i got the car it was on 3/4 tank and then I filled it up once after that. Sincxe I have gotten it I have been getting 12.5 mpg (200-205 mpg to the gas light comes on) Has anyone else gotten such a low mpg since driving the Rogue. (My 99 yukon denali gets 200 miles to empty)

any suggestions will help

There is something definitely wrong there. Unless your driving an insane speed and doing burnouts at every stop light, I don't see how a perfectly good Rogue would get that poor of gas mileage. See your service department.

[EddNog]

So you guys know, both Rouge660 and cashedup666, when I received delivery of my Rogue, the computer reported average fuel efficiency of something ridiculous like 12.3MPG. When I did my first fillup, I reset the fuel efficiency meter. A few tanks later, I began tracking and calculating my own fuel efficiency; here are the results so far:



As such, I would not worry yet; I'd say your results should improve. Note, however, that my computer is being optimistic about my efficiency.

You might try resetting the ICM (Computer) in the rogue by disconnecting the battery. It might have learned driving routines you would like it to forget. Also are you calculating the mileage, don' t count on the displayed mileage to be correct. Another thing I have heard is that winter blends of gas will not yield as high a gas mileage as summer blends a couple mpg difference could be expected. But if you continue to get this mileage take it to the dealer. As you can see from posts in this topic somewhre in the 20s is common.

[Lightforce18]

so the rogue says 87 octane only? Hey im all for saving money if this is true

[mmyye]

free way and city mix about 23.5 miles per gallonnot very happy about it.

Sounds like decent milage to me considering you have some city driving mixed in.

[DaleB]

2 week old SL 2wd, 900+ miles, 3rd fill-up, funny gadget says 23.9. Not bad for a 60+ old fart with a lead foot. Still much better than my last vehicle with 11 mpg, but not as good as my Honda CR-V topping 30 mpg, but the Rogue is more fun.

Hi,I'm from Brooklyn too . When I drive in Brooklyn I have about 17 mpg.But NJ TPike 33 mpg

How do you drive in the city (not Brooklyn) and have 22 mpg? Any special technique ?

[EddNog]

Yeah that's pretty darn good; I'm not getting 22MPG and I live in Scarsdale, which is a suburb north of the city (I commute into and out of midtown Manhattan daily, driving in during the 7:00-8:00 rush and driving home during the 6:00-7:15 rush, with medium traffic going down and lots of traffic going home). Although I am getting close to 22MPG, I'd be happier if I can do a bit better. I'm neither easy on the gas nor incredibly leadfooted--let's say medium-footed.

I have had my Rogue for more than three months. I average anywhere between 18 - 20 miles per gallon. All city driving. I think the fact that the CVT revs at high rpm when leaving a stop is the culprit. So far like the Rogue but not impressed with the gas mileage.

SL/AWD less then 1000 miles

312.6/14.723 = 21.23 mpg

[eugenekaraliou]

Hi, everybody. I am a new member here, just bought my Rogue S AWD. I havent calculated the gas milage yet, but it looks like it is close to 22-23 mixed (highway and city). Good luck

[Etch]

So far, with 500 miles on the clock, I'm getting about 23mpg mixed 50/50 city/hwy. I haven't done a manual calculation yet though.

[exeunt]

Once again I seem to have clocked just under 20mpg. Man, who knew I was such a lead foot.

I'm going to make a determined effort during this tank to keep my heavy foot off the gas and to leave the car warming up less often.

[babbot]

OK... I got the message that if I really want to improve my mileage I'm going to have to actually change some of my habits.

Thanks to the suggestion from YGBSM F-4G, I've kept my tollway speed under 70 (actually just barely under 70), and my overall mileage is up now between 23-24 mpg on my gauge. I'm really not sure of the mix that I'm driving, since there's serious road construction that's lousing up traffic).

I have a couple of related questions for those who are knowlegable:

1) Does running the defroster hurt mileage as much as running the AC ?

2) Does running the heat hurt mpg, and if so does the fan speed matter ?

3) Do the seat heaters and other electrical drains on the engine impact mpg ?

4) How much impact does cold weather and winter mix gas have on mpg?

Thanks for the insights.

[bill875]

I am up to 23mpg with 80% Highway and 20% city driving. Not too bad, but I wish it was better.

Maybe that dealer installed spoiler helped

Good questions... I'll share my knowledge or at least educated guesses on the topic with you. 1.) No, the defroster should be less parasitic on the system and thus hurt milage less than A/C would. The defroster is an electrical system that would pull from the alternator... probably not much affect on gas milage as the alternator is turning with the engine anyhow. The A/C system is an engine accesory which is belt drive as well.. putting extra work on the A/C system would impact the efficiency of the engine. 2.) I don't think running the heater would have much affect on gas milage. All the systems in the automobile are symbiotic with the engine. The engine turns the alternator via a belt to provide electricity to the car. The belt for the alternator is always turning with the engine, so it will always provide a certain amount. If you over-tax the system, then it may work harder to provide more power, and that could drain a bit more gas.. but assuming your not powering multiple electronic devises outside of the regular car system, the basic amount of juice provided by the alternator should power the electric fan and the blower for the heater system. 3.) The seat heaters, etc.. would drain the electrical system a bit, and that electrical drain would pull some power from the alternator, which if over-taxed would make the engine work a bit harder to supply that electricity. But, the effect would be minimal on gas milage. 4.) Cold weather and winter mix gas have large impacts on efficiency. Nothing you can do about it. A cold engine runs poorly and uses more gas. Winter mix gas does not burn as efficiently and will give you worse gas milage. I'd guess winter is probably robbing 2-3 mpg from my car... Plus it gets worse if you are the kind of person who likes to let the car idle for a while to warm up.

Turning the Defroster on automatically turns the AC on in the Rogue. (to remove humidity from the air)

[Redroguer]

Just got my Rogue last week. SL AWD version. 50-50 highway city driving. Tried to keep it under 70 on the highway. Mine does not have the trip computer so I had to figure it out the old fashioned way. 26.5mpg on the first fill-up. I'm happy with that! Sure beats the 16mpg I was getting on my 2002 Mazda B3000 pickup I traded in! Now if I can get my window to work!

ThanksGarry

Allow me to clarify the clarification...

FRONT defrost modes automatically trigger A/C; this uses extra gas. REAR defrost does not use extra gas, as it is a purely electrical system.

My trip computer is not as accurate as the "old fashioned" way. I was showing 31mpg on the computer but was actually only 27mpg. That was the biggest discrepency gap. Mostly it's only 2 or 3 mpg under the computer.

[redparogue]

With 1200 miles on our SL AWD we drove from PA to SC. Mielage ran from 26 to 28 calculated the old fashion way (computer numbers were always higher than actuals) while driving 70 to 80 mph. Trip ended with 2800 miles on the odometer. Note although in PA we have a CA Emissions model (slightly lower horsepower but the sticker mileage estimates are the same as the non CA Emissions.)

SL AWD. mountain drive 310mi. 29.3 mpg.
