CHATROOM: MPG 1st & 2nd Gen

[philipa_240sx]

Do you know if something like that exists for the US?

I am really not familiar with US laws. I know there are incentives for hybrids and alternative fuel vehicles. You can read more here:

Winter has been brutal on the gas mileage.

My last tank was a paltry 10.89L/100km (21.74 MPG). In the heart of summer, I was getting 8.13L/100km (29.15 MPG).

Cold temperatures have led to longer warm-up and idling time, more bumper-to-bumper traffic, inconistent tire pressures, engine operating cold, winter gas formulations amongst other factors.

Yikes! I've never tracked fuel mileage this precisely, but 25% reduction during winter months seems a little excessive.

[Pescakl1]

With my RAV4, I used to do about 8 LHK in summer and about 12 LHK during winter.From what I remember, I think it was the same figures with my Subaru Legacy.

Right now, I am still under 10 LHK (9.5 LHK on the last tank with more city than usual because of the Christmas holidays) while I was closing on 7.5 LHK at the end of summer. On the current tank I am just at 10 LHK and decreasing because I played in the snow... and lost ( I had to shovel for a good 15 min... forgot than I don't have the AWD).

Since the car is garaged for the night, I am just 1 LHK more on my morning commute but for the return, I am more than 2.5 LHK above what I used to do in summer. When there is rain or snow, everything goes up of course.

I hope to keep it under 10 LHK during all winter, I will be really happy.

I have had my Rogue for nine months now. I have calculated mileage every week since owning it and consistently get between 30-33 mpg. Only once have I gotten less than 30 mpg and that week I purposely drove it a bit more lead footed just to see how much it affected mileage. I believe I averaged 25-26 mpg that week. I generally keep the rpm's at 2,000 or below upon acceleration and I live in a year round warm climate. Mileage is significantly affected with the CVT depended upon driving habits. Mileage is double what I was getting from my former vehicle, Jeep Cherokee(15mpg). But now that gas prices have come down, I must say, I do miss my Jeep.

[zesty2b]

Have had my Rogue nearly one year now and nearly 8,000 miles, most of them in this very hilly town, so my one continuing disappointment with the vehicle is the gas mileage. In town, I rarely do better than 19 mpg. Even on the highway around here we traverse hills, and best highway mileage has been 25 mpg. I use Mobile One oil and am still on the original tires -- no snows yet because tred is good in those. It's hard to keep it under 2,000 rpms and climb hills, which we have to do to go home. Have to go uphill to come back downhill on this one-way street, every time we come home. CVT is gas conserving only if you can keep the thing at an low and even rpm, and that is not possible here. Otherwise, love the car. It's a great trip car and handles well in snow. Love the Bluetooth, the comfy seats, the quiet ride, and the smooooooth transmission. Just wish the mileage were better.

I have 2008 Rogue SL AWD that is fully equipped that we purchase in July 2008. My wife and I are seniors so we drive conservatively, probably 70-30 mix between city and rural. When we first started we were getting only 15.5 MPG. When the A/C was no longer used due to cooler weather we get 23.5 MPG. I guess we will know if it was just needing a break-in period or not when the weather warms up again in the spring.

[RobbyUSMC01-06]

I usually get around 22 mpg (75% city driving). I'm pretty happy with it though because I usually drive about 20 mph over the speed limit and I have 20" wheels on it.

[Stunnerable]

WOW.. I can't imagine not driving lead footed. SL AWD with 15K on the clock and I'm averaging 19-22MPG city/highway driving. It's better than my other car where I get a constant 10MPG.

[mx6bfast]

After my last fill up, I am at 7370 miles with an overall average of 25.18 mpg. I do a whole lot of interstate driving to work. My wife does a lot of city driving to her work and she has the car now because she is pregnant (I get her Mustang) and I'm sure the average will decrease a little bit.

My last tankful I got 27.77 mpg and the computer showed 27. I even saw it hit 32 shortly after I filled it up. I hope to hit the 30 mpg tank. If not that's cool that I'm getting this kind of mpg.

[whopitty]

Has anyone tried to use the tiptronic shifters in the city to keep rev's low? I find in the morning mine will rev above 3k RPM even if I accelerate gently. It seems the CVT revs differently based on how warm the car is.

Yes, this a function of the CVT computer. During warm-up, it uses lower gearing (and higher engine rpms) so less load is placed on the transmission to reduce wear. I would let the CVT do it's thing when cold and start shifting after it's warmed up some.

[kccruz2009]

so far... i have reulted mileage at average 23.5 mi/gal on my sl awd in city driving....home/work/home

[RobbyUSMC01-06]

Thanks to an abundance of speeding tickets, my mpg has improved from about 22mpg to about 29mpg. My avg speed during my commute used to be about 85-90 at 2700rpm now it is 65-70 at 2100 rpm. The difference in fuel economy is amazing! My old civic got 35 mpg if I went 120 or 45, didn't matter.

[philipa_240sx]

High ground clearance and even taller roof lines usually do not help fuel economy. It's not surprising the Rogue's fuel economy drops like a stone above 70mph. Wind drag increases exponentially with speed. Your smaller/lower ground clearance Civic is likely far more aerodynamic.

[kross1]

We have a 2009 Rogue SL, AWD, Venom Red, fully loaded.

Our trip computer is reading about 24.5, but last tank was actually 25.5. This is the highest we've gotten so far, we have just over 3,000 miles in the 1 month we've owned the car (Yes, we drive a lot, 75% highway/25% city).

I've noticed that the trip computer average, and our actual MPG are typically different by about 1 MPG, and both have been steadily increasing over time, previous tanks had worse MPG.

I expect the improving fuel economy is due to the vehicle getting broken in, and us getting used to the vehicle, and driving it more economically/appropriately. Yes, wind-resistance is a big issue at speeds over 70 I think.....

And I have to check my tire pressures, as the car "wobbles" like it is being wind-blown, even when it is not windy, at 65-75 MPH. This will of course also affect tire wear and fuel economy....????

[SewinSew]

I have had my Rogue for 2 weeks. I have filled up once and my mileage was 21.6. My trip computer said 21.1. I had made two short highway trips-70 miles round trip and 75 miles round trip-on that tank. The tank I am on now is all around town, so it will be interesting to see what my mileage will be.

[NismoPhan]

Been filling my tank about once a week now. And lately have been averaging about 23 mpg with about 50/50 city/highway. I've definitely seen an improvement in fuel efficiency within the last 1000 miles. I've got about 6000 miles on the Rogue now. When I first got the Rogue it was only doing about 19-20. Planning to take a decent road trip at the end of the month. Eager to see how an all highway drive will pan out.

[Pescakl1]

Right now, I am aiming to get 900kms on the current tank, I will tell you if I succeed at the end of next week.

Dude! One day you're going to report a story of how you got stuck on Highway 40 and have run completely out of gas. I hope you have CAA-Quebec!

I am closing on it. The stars did not align this time (no fuel pump in a good portion of my commute so I had to fill up to be sure I reach the other side).I was heading to it but yesterday a bus blew a tire on a bridge and I got stuck during 20 minutes in a big traffic jam.

But here what I got this time: 873 kms with 65.6 l, so 7.5 l/100kms or 31.3 mpg.I could probably reach just above 900 kms on this tank but I had to go at least 920 kms to reach the next fuel pump.So may be on this tank, but for sure this is feasible.

[ahhbeebee]

Wow!

The best I've done is 7.9 L/100km. and the most fuel I've put in the car is 61.3L.

[Pescakl1]

Now on my commute, I often do about 7 to 7.2 LHK (on 55 km). That is my weekend driving which moves the fuel consumption higher as the car doesn't use that much the fact that the car is warmed up (just some km here and there).I was still surprised that I can do about 8 to 8.5LHK with just city driving, quite impressive for a SUV.

Here is some tips for those interested:

As long as the car is not warmed up, stay as light as possible on the gas (no more than about 1600-1700 rpm). Since I do that I cut my fuel consumption by about 0.5LHK on my 55 km drive, that is really effective.When warmed up, don't go over 1500 rpm at a start and try to stay about 1200 rpm when accelerating, you will be surprised that the car accelerates quite well.Try not to go to a complete stop (look at the other light going amber then red) as it takes more effort (more fuel) to move a car from zero than from few KPH. Try to stay as close as possible to the law .

When the engine water temperature reaches 50C, the higher rev to move the car is gone, and regular rev are applied to keep the car alive at a stop, but you still don't get no fuel when cruising to a stop or red light, it is only occurs when water temperature is above 70C. Then you can start having some real fuel economy when releasing the gas pedal.So more stops you have to do when the car is not yet warmed up, more fuel you will use. More you can cruise and have a constant speed when the engine is not warmed up, more fuel you are going to save.

The first quarter is the most important when you want to save fuel, it will determine your final fuel consumption, whatever you do after.

[Pescakl1]

Oops, forgot about filling the tank:Our fuel tank is 68 liters + pipes (I did several tank refilling at more than 68l).

When you fill it up, a the first stop of the pump, you are about 1 gallon short of a fuel tank (more or less depending of the pump), but there is a better way to know when it is almost full:At about 1 liter short of a full tank, you will hear some gurgling from the tank as the air tries to find its way out, chased by the fuel.That is a precise and easy way to know where you are: When you hear the noise, complete your fill up to the next $ if you want a round amount or add about 1 liter.

For my part, I have a scangauge, and by iterations, it is now really precise so I know what quantity to put in the tank.

There have been times when I've put near and over 16 gallons in the tank. I know that the tank is actually bigger than the 15.9 advertised. So are you saying when you hear the gurgling sound the tank is considered full? Should I think about stopping soon after I hear that sound?

Are there any dangers or drawbacks to filling it too much? I usually fill it up quite a but with the stopping/starting/slowly pumping.

[Pescakl1]

16 gallons? You are about 2 gallons short of a full tank.

From my experience, when you hear the gurgling, wait for the gurgling to stop (all the air trapped in the tank to go out), and then you will have about one (probably a little more) more liter to get it full.In the US, you fill in gallons so that may be harder to know where you are, but here in Canada where the price of fuel is about 1$ for 1 liter, I was used to try to go to the next round $, and depending of the price at that time and when was the gurgling, I was putting about 1 liter more before being at the top, sometimes more. I never really looked at the amount of fuel, more at the amount of money to pay which leads me to sometimes see the level of the fuel in the tank (really really full).Now with the scangauge, I go to the amount of fuel the scangauge tells me and start from there to try to see the level of the fuel, and look at what I have to pay after.

Any drawbacks of filling too much is spilling at the end, as you kinda fill it up cup by cup (you have to move back the nozzle and look at the fuel and stop manually).Other drawbacks: Take more time to fill up (no too good when there is a queue), you may look dumb bent to look at your fuel tank, and last one, you lose some fuel as you replace some air saturated with fuel vapor by fuel (that is why it is better to do it engine cold and early in the morning, fuel is more in its liquid form).

Advantages: more range and the pleasure to drive the first 100 miles kinda free as you will still have all the squares on your dashboard .

[mx6bfast]

I think the most I put in was just under 17. That was before I knew the tank was bigger. I thought it was really really empty.

[mx6bfast]

I got gas today and finally passed the posted highway mpg. 28.1 mpg after 10917 miles. I've been in the 27's a few times. It surprised me because I wasn't paying attention to the actual miles until I did the calculation. The computer read 26.1, one of it's "favorite" numbers.

[RO-G]

So far at 1407 km., I'm gettting 11.5km/liter or 27mpg.

[Elton Noway]

Well... based on the responses I'm seeing in this thread I must have a hole in the gas tank.

2009 Rogue SL FWD. All city driviing so far... but at a relaxed comfortable pace. (still trying to baby the car) Anyway... we're well into the second tank of fuel and only averaging 19.8mpg!

Your fuel mileage does not seem too unreasonable. There are others who have only been getting around 20mpg in city only driving.

How many miles so far? It usually takes 5000+ miles for the engine to break in and get better fuel economy.

[philipa_240sx]

I had a good trip this weekend to Central Ontario. 500+km all highway each way. The trip up normally nets slightly poorer fuel economy possibly due to the increase in elevation. The trip home however was fantastic. Add some city driving and I covered 420mi (677km) on 14 US gal. (53l) for a fuel economy of 30mpg or 7.8l/100km.

[philipa_240sx]

So far at 1407 km., I'm gettting 11.5km/liter or 27mpg.

When converting l/100km to mpg, please convert to US MPG for our American friends. The Imperial gallon is 20% larger than the US gallon and it's very confusing.

Here is the calculation

US MPG= 235/(l/100km)

In your case:

235/11.5= 20.4 US MPG.
