Hi
New 07 S AWD. Currently getting 16 MPG with only 500 Miles on the engine. I assume my MPG will improve with time and miles put on the car, but I wanted to make sure. The need for premium is killing my wallet as Im sure everyone elses since I need to get gas every week now.
Thanks,
Ralph |

| I'm at 2k on my 07 AWD. My hand calculations show an average of 17 so far. Im hoping it will improve a little as well. V6 at 4k lbs wont be much more I guess. I have been running premium and reg with no difference in mileage, performance changes slightly. Its not required to run premium, try running regular and see if the performance is acceptable. |

Yes, your fuel efficiency will improve as the miles add up. Every new engine is "tight" and needs to accumulate miles and hours before they loosen-up. My MPGs increased up until about 10,000 miles and have appeared to level off.
Also, there is no need to use Premium. Regular and mid-grade gasoline is just fine.

All, Thanks for the replies.
NJJOE. I see that the premium is used for the anti-knocking purpsose. I had a 97 dodge durango, and used regular, every now-and-then, I would hear the engine ping and then I would fill with 89. I assume I can do the same in my murano, right? I figured I would used the premium at least during the first 1500 miles, or is even that a waste?
Thanks again,
Ralph |

The MO will run just fine on regular-grade gasoline. The VQ-engine has a knock sensor that will retard the ignition timing if knocking (detonation) is detected.

Right now a mix of city and highway, 60% city 40% highway. |

Yeah, Nissan has a unique way of wording things. If you look at the Murano's home page, Nissan lists AWD as "STANDARD" for all models and lists FWD as an option. I don't know who they are trying to fool.

We have a little over 10,000 miles on our 2007 SL. We are getting about 18 mpg in city driving and 25 mpg on trips.
Make sure your tire pressures are at at least 33# psi when 'cold'.

| It also depends how long/far you are driving. I find that on my short 5 mile commute, I am lucky if I get over 15mpg overall. On roadtrips, I can get over 20mpg (just over). Mixed driving is somewhere in between, but distance of driving matters a lot. |

Had mine since 2005 and have always gotten between 18-21 daily and 23-25 traveling. Regardless of what anyone says and even though I'm supposed to be able to run 87, it knocks like a maddog anytime I've tried so I also have to run 91 to keep it from pinging.
I'll be Advancing the Initial Timing 2 degrees before long to see if that helps reduce the knocking. It helped improve my MPGs in my Armada so I'm hoping to see similar results in the MO since it also worked for my little Bro's 350z. |

Advancing the timing will likely *increase* the knocking if you already have that problem on regular 87. The idea of using premium is that it allows the computer to advance the timing to take advantage of higher compression before detonation. |

Pops-
No way; don't even consider it. Advancing the timing will only exasperate the problem.

Hey Ralph,
I suspect your MPG will drastically improve. I average 11.5 ltr per 100 km's - which (when I press the button to convert to MPG) works out to be 20MPG - which seems to be the norm here.
I also use premium fuel as I find that the engine works better. As well, I have a K&N filter. There are folks on both sides of the fence for benefits of a K&N; largely I went with it for enviornmental reasons (stop filling land fills w/ filters) but I also noticed a modest improvement in fuel efficencyand performance when I made the change.
Good luck! |

I get 21.5 mpg from week one.
On the pinging/should I use premium thing:
We have hashed this out many times here.
It seems folks don't realize that the VQ is a high compression engine. You can not compare it to a durango. The higher compression an engine (after 9.5 to 1 ratio), the easier it will knock on regular gas. VQ is a 10.3 to 1 ratio engine. It is PRONE to knock on regular gas. It has to RETARD ignition to work with regular (if the knock sensor is working correctly).
I don't know about anyone else, but I would rather my Mo run as designed instead of retarding ignition to save a few bucks per month on fuel-- besides that, any knock (in my book) is a bad thing.
Gasoline is supposed to do a quick "fwoof" instead of BANG inside the cylinder. Bang is bad for all sorts of parts, beside the fact that it will carbon up your cylinders/rings/plugs/valves. |

| Thanks Guys!!! You're right. I'd have to retard it 1 degree or 2 but I don't want to do that so I'll leave it alone. |

I bought mine used. Its a 2005 model and I get 22 for my work commute and 24 on the interstate. But then I live in a small city so work commute has just 3 stop signs and practically no traffic. My highest MPG was driving the day after thanksgiving on I 95 at 55 MPH constant because of traffic. Apparently I got 25.4 MPG all highway with 1 dead stop for 4 mins.
Only change I made was a KPN air filter. I use regular sams club 87 |

No. It will not improve. Unless you slow down.
Let me ask you a couple of questions for your own introspection:
General Question: How is your driving habit?
1. On the street, do you often floor it out of the lights, and then come to a heavy stop at the next?
Or do you ease up to speed and then cruise down to the next red?
2. How fast do you drive on the street? Do you drive above 40MPH consistently on the streets?
3. How fast do you normally drive on the freeway when there is no traffic? 65MPH? 70? 75? 80+???
4. Do you change lanes often on the freeway?
5. When your freeway exit approaches, do you keep the speed up as you change lanes and then scream down to the stop? Or do you cruise carefully and glide down to the stop?
Me: I get 21MPH generally.
I never drive above 40MPH on the street, I do not floor it, and if I see the next light about to change, my foot is off the pedal already and I cruise to it. I am never in a hurry. I don't hound the car from lane to lane, I don't hound the car for change in speed, I plan well ahead for my exit and I cruise over to it. Believe it or not, this car will cruise for a very long stretch at a good speed if you're heading to a stop, so I just let it mosey on over to it. I am very easy on the pedal.
On the freeway around the city, I tend to cruise around at 65MPH. Sometimes at night when it's clear, I may do 70. Yeah and when I say city? We're talking Los Anggggeles, so think about that for a second.
Out of the city travelling across the countryside with very little traffic and a specific destination to go to, I may do 75-80, but never above 80. Oh and when I say countryside, I mean the desert heading to Las Vegas or something where, on the I-15, people are driving 90MPH these days heading out there. Stooopid.
Oh yeah and you don't need to put Premium in it, by the way - it'll run fine with mid-grade. Unless you race with it or something.
If you read the above post by Menonan, you can tell that this car is not meant for hard driving like that - it's a heavy car than normal and so you have to drive smart to get good MPG. |

One thing to keep in mind is that your fuel mileage will improve with higher octane fuel (to a point). You need to figure out which is the most economical fuel to use.
For example, say you can get 87 octane for $2.89, 89 octane for $2.99 and 91 octane for $3.09. You run a tank of each through your Mo and find out you get the follwing fuel mileage.
87 = 20 MPG
89 = 22 MPG
91 = 24 MPG
Your cost per mile breakdown would be COST OF FUEL divided by MPG
87 octane = 14.45 cents per mile
89 octane = 13.5909 cents oer mile
91 octane = 12.875 cents per mile
In this example, even though 91 octane is a more expensive fuel, it is the most economical to use. |

yes the gas mileage will improve- i just got my 07 and like you
got the 16 or so mpg when the weather cold-now i have 1500 km and during mild spell it went to 20 mpg average and in summer will be better-thats not bad for a 4000 lb truck-my last car an 04 altima with a 4 cyl was only getting 20-or so in the city during the cold weather-plus with the nice 6 cly its more fun to drive
Enjoy your car |

I bought my '04 back in July of '04 and was initially getting between 11.5 - 13.6 mpg in the City (Los Angeles) and barely 19 mpg on the freeway. I had that same horrible mileage until 10k miles, when I started to notice slight improvement. Now, at 45k miles, driving the same streets, in the same traffic, and with the same driving style I average 18 - 21.5 mpg in the City. On the highways over long distances I have been getting about 24 mpg at 65 mph and around 21.5 at 75 mph. Obviously, at higher speeds there is a major sacrifice in fuel efficiency.
Years ago on this forum someone recommended that on the freeway you floor it and then bring the car down to your cruising speed. The theory behind this has to do with the way the CVT settles at cruising rpm when accelerating vs. decelerating. I'm not a techy so can't speak to why it works, but I do find that this technique will get the CVT to cruise at a lower RPM than if you reach cruising speed by accelerating into that speed.
Btw, I only use 87 octane. |

I do tend to drive my vehicles "fuel smart" in certain ways, such as anticipating stops ahead of time and easing off of the accelerator (or in the case of my 6-spd manual transmission car put it in neutral).
However, driving in the manner you describe would suck all of the enjoyment out of driving a sportier vehicle. If I want to blast off of a stop light periodically or exceed the highway speed limit when I feel it's safe to do so, I certainly don't stress out that it might cost an extra $10 monthly in fuel!! |

Well, geez if it's only $10 you're worried about, just don't see a stupid movie for that month! hahahaha
(or buy one of them expensive soda and popcorn packages)
I'm not saying that you should drive like me, or drive as if you're trying to help the environment a little bit - I'm just saying that there is a limit to the average that this thing will do, and that is all.
I thought you'd been driving like a 16-year old who just got his new car and wants to scare his girlfriends sh_tless in the back seat as they go sliding around back there! hahahaha
OK so it will improve a tad from 16MPG. But I can tell you that for me, as soon as I try to do a couple of extra manoeuvres or try to be in a hurry and forget about the fuel-efficient driving style? It goes down fast. Below 20MPG regularly when I floor it even just a bit above the careful driving style.
So there you go. And remember I have AWD. That weighs it down too, and I think I'm doing well for having AWD. |

I've been using the K&N on the MO and Armada for about 6mos now. I got it for it's endurance, it seems to run very similar to a clean stock filter. I've also heard rants about the new Amsoil no-oil Air Filters being the best thing since sliced bread. |

| My wife got 23.5 mpg on her first tank in 50/50 city/highway mix (only had 45 miles on it when my wife got it NEW). I'm not complaining AT ALL! BUT, will it get any better? That would just be completely and utterly insanely awesome if it did |
