So I have had the car for about 600 miles. Most of my driving to work during the week consists of 60% highway (speeds of 50-65 MPH) and 40% city (speeds of 25-35 MPH). I am averaging 27 MPG. Yesterday I took my first drive to school. It's about an 1 hour and 15 minutes drive (around 65 miles), mostly highway (Speeds of 50-65 MPH) and I was able to get 32 MPG on that one drive. I was wondering what the rest of the 8th Gen owners were averaging on their cars?

 

I do a mix of city/highway leaning towards city and am getting 22.5 overall, which is 1-2 mpg better than I got with the 7th gen.

 

at 1500 miles I am averaging 30.3 mpg......not sure why??

 

18 mpg in my SR

 

About 24 mpg so far, 600 miles, mixed driving 75% city/25% highway.

 

8.9 mpg here

 

Unless you floor it everywhere you go, that doesn't sound right.

Also, the best way to calculate mileage is when you fill up. The readout in the car isn't exactly accurate.

 

I know in my 2015 Murano...the readout has been surprisingly accurate. It only varies 0.2-0.4 mpg off hand calculations. Let's hope the 2016 Maxima's are similar in accuracy.

 

It doesn't sound right to me but that is what it says. I drive normally. I live 3 minutes from work. I have driven only 78 miles since I got it 2 weeks or so ago.

 

On my way back from Phoenix where I bought my SR, I was at a little over 32 mpg. That was about a 335 mile drive. Here in town, mostly going to and from work which is mostly freeway, I'm getting a little over 22 mpg. I'll pay better attention after my next fill up.

 

About 24~25 mpg. Average trip speed is about 30 to 35 mph. Not much stop and go, just 2 lane roads, with a 10 min commute to work.

 

Did you reset your MPG reading when you bought the car? 8MPG does not sound right.

 

8 mpg is like a Hummer or Excursion. Maybe you sit idle a lot but thats not acceptable... Def missing some info here.

 

Idling for long stretches will drop the mpg reading. Do you use the remote start and let the car run at idle? You are getting 0 mpg added to your average....

 

No, I did not do that.

 

I used the remote start once and let it run for about 3 minutes. I have also sat in the car with the engine running for about 10 minutes while learning to use some of the features.

 

I recall posting a list of around 40 variables involved in measuring fuel efficiency here on maxima.org around ten years ago. Many were minor things, such as temperature, front-to-rear slant and side-to-side slant of the car when refueling, cutoff point at which the pump nozzle is set, etc, etc.

The only really accurate way to measure MPG is to use the same pump at the same station each time for several fillups, recording gallons and mileage at each fillup. That assures the level of the added fuel is reaching exactly the same point at each fillup.

But then we know that we will be encountering different driving situations every time we leave our driveway, so extreme accuracy is not possible (or even meaningful) outside the laboratory. But, in my opinion, any MPG derived from less than several fillups should be viewed with a jaundiced eye.

 

I reset the MPG reading today. Now I am getting 11.9 MPG on my 3 minute ride to work.

 

FAIL

 

You're not driving enough for it to register an actual MPG number. My drive to/from work is around 25 minutes one way and it takes nearly half that to get to a true number. However, that number will go up or down depending on driving. I would bet on your next fill up that if you calculated it manually it would be a lot higher.

And 3 minutes? I would ride a bicycle.

 

LOL, you do not understand, this is my bicycle!

 

We just took it on a 650 trip. About 50 miles in town and the rest on 70-75mph interstate. Averaged 31.9 for the trip.

 

Now that it April 2016. Time to get this thread going
again since last post was July 2015. Just completed a 234 mile trip.
Computer is showing 34mpg. Trip consisted of traveling
55 on most roads with some 70-75 on some sections
where allowed. There were also some lights. I used
Cruise on 75% of trip. I am very happy with that number even if
computer is off some.

 

I have a 25 minute commute mostly slow city driving with a couple miles of highway, and I get less than 21 on most trips. Haven't had a highway trip 1000 miles in yet...

 

Took a 4 hour round trip to west palm last night
248 miles in half a tank, over 30 mpg
And comfortable with the seat heater on low
No more back ache!!

 

I am averaging 23.0 mpg.
-Average daily commute: 24miles R/T in a lot of stop and go due to traffic lights and traffic. Long lights too here in San Diego which adds to idling time.
-80% stop and go/20% highway
-Driving style: Smooth and controlled but somewhat spirited. Try and coast to red lights.

 

I have taken two road trips in mine in 6 weeks and 3700 miles. On the last trip I averaged 32.9 It was up to nearly 35 until I hit the 85 MPH toll road around Austin. I confirmed it by fill up to fill up calculations.

In town it varies from 19 to 25 depending on the type of roads and traffic.

 

Just a question guys ...what type of fuel do you guys use? Premium or regular? Does this car requires premium only ? ...thanks in advance

 

There have been hundreds of posts regarding this on this board (and on the boards of every generation Maxima). In short, octane is not tied directly to MPG, but IS tied to performance. Many here use regular (87 octane), as they are not interested in great performance. Others here use nothing but premium (91 or 93 octane) as that is recommended by Nissan and gives maximum performance.

I have owned nothing but Maximas since October 1984, and always use premium the first 18 months, then midgrade (89 octane) the rest of the time I own the car. I have found that, although electronic devices would detect the difference in performance between premium and midgrade, I have not been able to detect that difference by the 'seat of my pants.' By contrast, some folks here can detect a slight dropoff in performance when going to regular.

Just be aware there will be 19, 347 opinions here, so use your own judgement, and go with what makes you happy.

 

Actually, the EPA ratings given are with premium fuel. You will get better fuel mileage with premium. Your car will run just fine on less than premium; however, you will likely get less MPG. However, the higher cost of the higher octane will not likely be offset by the savings in MPG.

Yes, the testing is done with premium because the auto manufacturer recommends premium. Premium is recommended because it gives maximum PERFORMANCE, not improved MPG.

I have never measured any difference in MPG between midgrade and premium since car fuel systems improved to where the timing automatically adjusts based on the type of fuel encountered. Regular may lower the MPG if the car's fuel system does not adjust the timing enough to handle it properly.

I have read in auto mags and technical journals for decades that octane has no bearing on MPG in a car with a fuel system that can properly adjust for the octane encountered, and this Maxima can adjust to midgrade, and in many cases, adjust down to regular.

There have been many threads on this here on maxima.org over the last ten to fifteen years, and this misunderstanding is always eventually settled by a few techies amongst us giving references to complicated laboratory studies that are more precise than our real-world experiences.
