I have read that the tank size on the Murano is 21.7 gallons. I question that based no my fill up today and in the past. I was gettign 16.9 MPG with 50 Miles Till Empty. If I do the math (50/16.9) thats roughly 3 gallons left in the tank, if I subtract 21.7-3, when I filled up, I should have gotten roughly 18 gallons, but I only got 13 and the needle was all the way up. Also, my Miles Till Empty read 284, I am seeing on other sites, I should be able to get more then 350 miles to a tank.
Does this sound right or is my thinking all wrong? If I use a different gas or a different gas station, I am seeing the same thing.
Any help is appreciated.
Thanks,
RalphTrent

| anybody? Can you at least reply with your fill up experiences? how many miles to the tank do you get (at least what the computer shows)? |

I get anywhere from 385 - 415. |

There's actually a 'secondary' tank. The main tank is 18 gallons with the 'secondary' being 3. Only the 'primary' tank is taken into account for the mileage calculations on the display. So you can drive several miles after you reach "0 miles to empty".
I know 'secondary' isn't the right term, but I'm drawing a blank what it's called right now. Someone can correct me. I know I've read posts in the past from people saying they drive a certain number of miles after they reach '0'. |

| There is one gas tank and it holds 21.7 gallons. When the low fuel light turns on, you have about 3 gallons left (this is called the reserve, but its still from the same gas tank). Do not rely on the distance to empty reading - it is very conservative. I've driven a bit with it reading zero (well it displays * instead of zero). |

I think everyone relies on the DTE.... is dynamic and will/should change often... say if you stuck in traffic or on the highway.
The issue I believe is that someone is on the highway... they get off the highway and are stuck in traffic. I checked once but can't remeber how long before the DTE shows the correct information given the new conditions.
I never use the DTE, I know what my MO is giving me for milleage and know I have 21.7, I also know that I try not to let it go below half.
I also aggree with others in that I find when the light comes on you have about 3 gallons remains... how far you will get depends on the driving I am currently doing and will encounter (in the very near future). |

If you search on DTE you should get a few interesting posts on this forum. Many people have reported driving many miles after DTE stopped displaying a value. I don't remember anyone here ever reporting that they ran out of gas, but may people have reported DTE going all the way to zero (or *). It is a rough guideline, and should not be taken as an accurate measurement.
So, if you REALLY want to experiment with it, you could take a gas can with you, and let it go all the way down until you run out of gas. Use your spare gas you brought along to get to a gas station, and see what the numbers are then.
Of course, I strongly recommend AGAINST purposely letting ANY car run out of gas, but if you REALLY want to know... :D |

| Thanks for the idea, but what about the size of the tank issue. Does That make any sense? |

Thank you - "reserve" is the term I couldn't think of. :) |

The "miles till empty" calculation does not include the 3.7 gallon reserve. If I fill up right as the "miles till empty" is almost 0, I get 18 gallons. So calculate back from 18 instead of 21.7. Doing so gets you 18-3=15 which still isn't quite on the mark but it's much closer.
And 16.9? Ouch! I rarely see mine under 20. I see it dip into the 19's sometimes when it's very cold. Although the computer figure does tend to be just a bit high. The screen read 23.0 about 1/2 tank in when I parked this morning. The real figure is probably closer to 22. I've had my MO since last May and the manually calculated MPG for that timeframe is 20.78. |

Yeah, thats if Im lucky. Any idea's on how to improve that. I have 3400 miles on the car. People say its still breaking in, but I think I am beyond the break in book (According to the manual, which stats 1200 miles). I have replaced the air filter with an K and N. I did find that using premium does NOT improve this number, in fact before my most recent fill (which was premium), i put in regular and was getting about 17.4 MPG.
I do not driver at high speeds, but i do mostly stop and go. On the highway, i was max at 19/20 MPG. So I am no where near the advertised MPG's. |

Like with most cars good mileage is not just about speed but also the gas pedal. If you are light and can keep the RPMs around 15-1700 during acceleration I bet your milleage would improve.
Why is your acceleration "style"?
I'm averaging just under 20, about 19.8, with manual calculations on every fill up. (using a great auto logger) However most of my driving is city When I am on the highway I do ride over the posted. However I do accelerate lightly. |

Ha! I wish I got 20mpg. I don't accelerate particularly quickly either but my short city commute of around 5 miles each way gets me only 15-16mpg.
I'll say it again - do not rely on DTE for an accurate measurement of fuel economy - it is a very conservative estimate. Once you get enough miles on your MO, you will figure out what MPG you usually get (regardless of what the computer tells you) and you can estimate how far you can go. |

With those few miles, you obviously have an 09 - I haven't read enough to know if the mileage dropped a bit with GEN2? |

I think the 2nd gen actually gets slightly better mileage from what I read in reviews. Remember the 1st gen was before the new EPA corrected MPG numbers. The sticker on my 03 AWD says 20/24 - what a joke! Its more like 15/20. |

I guess I have a light foot. With 35K miles my worst mileage at fill up was about 22 and the best was 25. The display can be 1-2mpg on the optimistic side.
As for the DTE display, has anyone noticed that at about 100 miles DTE the mileage starts to drop rapidly and creating a reserve?.
for example, on a just filled tank my DTE will show about 470-500 miles and drops at a rate consistent MOL with the odo. Once I hit the 100 DTE mark it can drop more than ten miles in one mile. |

22 is just amazing. What is your normal driving like? A lot of freeway? |

No, I have a 14 mile commute and am careful when approaching lights to keep rolling-not enough to annoy other drivers though! A section of the drive I can maintain 45-50 MPH for 5 miles and that helps. The rest is medium density traffic though sometimes heavy on the return trip. If mornings were counted only I am sure I would get 26 or better. Highway driving is about 23MPG.
The RPM's virtually never exceed 1300 except during torque converter mode when accelerating from a stop.
My wife borrowed the MO recently and the mileage plummeted when I checked the projected MPG.:2: |

Wow that is some *very* gentle driving. I guess I'm a lead foot - I rev it up to 3000+rpm almost everytime I accelerate from a stop. |

I have no problem keeping with traffic. WOW-3000 RPM all the time.
I leave that fun up to my yellow gentleman's express- 12,000 RPM and 0-60 in 3 secs:5: |
