edmunds and car sites are saying 375 miles, is this accurate ?

I just filled up to click and it stopped at around 16.5 gallons, 56 dollars.

Wow if I can get 375 miles on 16.5 gallons then I am happy!!

Maxima has a 20 Gallon tank. Did you fill up at empty? If I go to the line my car will take 19 Gallons so I got 1 more gallon after the line.

I get on average 19 mpg X 20 gallons = 380 miles. So sound about right. Now, on the highway I've gotten it to push 29mpg going 65mph on a flat road (no incline or decline).

On a normal road trip it'd probably average about 25mpg X 20 gallons = 580 miles. I have yet to take a road trip with it. Don't know if I'm looking forward to it with the constant pull to the right, still not fixed.

My normal driving, living 2 miles from school, I get 13-17mpg usually the higher side, my range/DTE is usually 330 with this short driving.

My weekend driving I get 19-20

My drive back to NY from GA, started out averaging 26mpg, some traffic, but stayed between 60-70, the rest of the drive, through the night my speed averaged 80mph with 90mph passes and I got 23-24mph, the last leg of my trip with going between 60 & 90 my mpg was 22

So as you can see the car is fuel efficient, all depends on how you drive, my range/DTE on the long drive went up to 445, can't get passed 450, my 06 the range went up to 525, with I could see that on my 09

i calculate my mpg everytime i get gas and im getting around 23mpg in the winter but in the fall i was getting 25-26mpg

Ghozt

do you find your manual calculations match up with the Nissan computer? just curious if anyone has done this type of comparison to see how accurate the computer is in gauging the MPG.

how much of that is straight free way driving and how much of that is stop and go traffic ?

LtLeary

I am a road warrior and get about 450 miles to the tank (16-17 Gal) of course this is 95% highway driving of about 80 miles each way. And yes, my manual calcs are pretty close to the computer.

BBmaxi - It is sort of nice to have an idea about how many miles we can get on a tank under various conditions and driving situations, and I sometimes look at that.

But keep in mind that the only truly accurate way to measure fuel efficiency is by dividing the miles driven by the gallons used. I would even say this needs to be done over a multiple fillup span in order to make for better accuracy.

Also remember that the nozzle cutoff is slightly different on every gas pump, even different between the three nozzles at one of those pumps that has a separate nozzle for each octane. Also, any slant or tilt of the pavement where the car sits during refueling means the gas tank will accept more or less gas than it would on completely level ground before the gas fills the refueling tube and the nozzle cuts off the flow.

And remember that the 'fuel low' light on these Maximas varies from car to car. Some come on after only 14 gallons have been used, while others come on after 16 or 17 gallons have been used.

There are other factors that can affect how much fuel you can put in your tank at fillup, but by simply dividing miles traveled by gallons used, you have the straight poop.

its a mix between highway and regualar road.. i travel 15miles on way on the highway to work and i set my cruise at 70-75 and on the regular road i do like 40-50 with little stop and start. i dont really put my foot all the way into the pedal to save gas.

when i did my calculations when i fill up it doesnt match up with the cars compute DTE. The DTE is always low by like 30miles.
my fuel light comes on around 18gallons.. when it came on for the first and only time it said i had 65miles to empty

I forgot another important piece of info to ask...what is your average MPH (average miles per hour).

My mph has been steadily increasing to about 24 mph (for the past 3 days) and I'm getting a reading of an average 21 mpg. My overall monthly average is 28 MPH (daily work commute) and in my previous 4 banger I was getting an average of 25 mpg at 28 mph. I'm hoping once my MPH get up to my true average driving speed of 28 MPH that my average mpg goes up to about 23 MPG. It looks like this will be the case according to the numbers I see.

I'm very light footed and only really press on it when I need the power to pass lanes.

MAX1MKA

on full tank i got 463 miles and computer was showing 20 miles to empty and i was able to put allmost 17 gallons with the speed of 80mph on cruise control

Dubl-A

Ive never been able to go over 18 gallons even after the indicator stays blinking. Out of those 18 I get about 450-480mi around 25mpgs

GM_Traitor3.5VQ

I've found that the average mpg calculator in the dash is about 1 mpg higher than what I actually average each tank. With 52 miles of commuting each day in heavy traffic, I average about 340 miles out of a tank and about 21 mpg. Virginia winters suck. I was getting 23 mpg easily this summer!

My old 2001 Grand Prix mpg average was also about 1 to 1.5 mpg higher than what I was actually achieving.

As long as I can average above 20mpg in the city, that's fine by me. Now that 93 octane is creeping up on $3.50 a gallon, I'm about to start filling up with mid-grade!

IFuXwiTuZ

isnt it 18gallons?

GM_Traitor3.5VQ

Yes, It's a 20 gallon tank, however the most I've ever been able to put in is about 18.5 gallons. I try not to run the fuel down to just fumes. Electric fuel pumps need to be covered in petrol so that they stay cool. No fuel, not cool!

so I'm getting 350 miles on a 16.5 gallon fill up, this is with low grade 87 octane. I will try 91 octane premium if I decide to keep the car.

SCR_speed

i only use the shell v power .. i always get the high grade.

maxxxxspeed

On my first tank (257 on odometer) Winter blend fuel 50/50 city/ highway I got hand calc'd 22.35 mpg.... Hopefully with normal fuel it'll get better...

Llfe

iTrader: (5)

wat? i thought u were suppose to put 91 octane from the start...if they had 93 in cali it'd be puttin that in instead

i've averaged 300-320 on a full tank 1/3 street 2/3 highway and i floor it sometimes

something strange = when i fill it 1/2 way...i only get like 130??

on long trips...it's been well over 450

Just got my range to the highest it has ever been 489, and that was doing 80mph and the computer said I was averaging 27mpg the 27 eventually fell to 25, but I was glad to see 489

maxxxxspeed

Yup when I fill it up completely my "Till empty" say anywhere from 465-490...

Coming from a 2011 Sierra 1500 where my best was 15mpg going 60 on the freeway I am happy...

smarty666

When I fill up in the winter and summer months, I usually get to 430-440 miles per tank and during the spring and fall I would say 460-470 miles per tank. Typically there is usually 2 gallons left when I fill up.

maxxxxspeed

running 20% City/80% highway (70-80mph) I got 358 miles and the "miles till empty" still said I had 124 miles till empty. I put in 12.895 gallons till it clicked. Hand calculated that is 27.76mpg... this is a 2011 Maxima SV with 18" wheels running 89 octane...I drive VERY conservative rarely seeing 2k rpm. Engine only has 800miles on it.

ArvindCpatel

I have 2010 SV with monitor package and have about 5500 miles on it. When I drive I always get around 25.6 miles-most of it local but in Merritt island, Fl, I don't have heavy traffic and few traffic lights. I am a very careful driver and use the brake very infrequently and also let it coast to the light. The car is relativley sensitive to how one drives. One week when my wife drove it, she got around 23 mpg.

MooShoo

I just got my 11 on the 1st. I've filled up 3x @ around 360m / tank. Not too bad. I've never run it down to see if I could squeeze 400 out of it.

maxxxxspeed

I could of EASILY gotten 400... More like 450-475.

I still had a quarter of a tank!

sg1214

Oh man livin in NYC takes its toll on me, lol. My miles till empty sees 368 if lucky, and Ill get to 300 when i have like 30 miles till empty. Time to move to FL!!

matts3.5

I'm getting about 180 per tank hwy. I brought it to the dealer and he said because of the gas they use in the winter it is common for your economy to drop 40-60%! Obviously the guy was an a@#$%ole.

maxxxxspeed

Are you driving in Sport shift mode first gear the entire time running at 6500k rpm? If that's true your getting Around 10mpg... My lifted F350 dually diesel gets better than that...

You have to be mistaken.

2010BlackMax

its so hard to talk to people about fuel mileage. To calculate it correct you must fill up, reset the trip or write down the mileage, then drive it and fill up again. Divide the number of miles by the gallons of gas used. Not difficult, but people just dont get it sometimes.
by saying i just got 180 miles in my last tank, that doesn't say much. How many gallons of gas did you use in the amount of miles you traveled. This is the only way to do this. Other ways are not accurate with comparing with others.

My last tank I got 95 miles!!! But i topped off before going out of town, my gauge was down to the 1st tick But I put in 3.6 gallons. So I got around 26.4 MPG. Computer said 26.5 MPG.

The most miles I have ever got was 537!!! Took 17.2 Gallons. Which means I got 31.2 MPG!!! I haven't come close to this again. It was this last fall. My wife and I drove back home and had a nice 10 mph tail wind the whole way home 6 hrs. I set the cruise on 71MPH and watched the gauge slowly go down. It was great!

medic1

hi guys..i only use shell v power 93 octane and the computer says average of 21 mpd..neber manual tested it..funny thing is it never changes from 21 mpg when i click status for fuel mpg..whats wrong

Chivalrous Catfish

Just filled up today. 29.2 mpg. Computer said 29.5. Highway, with some light traffic.

2010BlackMax

you have to reset the computer! Check your owners manual for the steps for your car

travis0385

i usually get around 425ish out of 16 gallons... I have 6k on the car and the computer is finally starting to be close to my real calculations (miles / gallons)

At first I was seeing like 27 on the computer but calculating 23-24... maybe break in period, i dont know

travis0385

the computer has sometimes said ~500 till empty after a fill up... never gotten that though

BlackMax11

my car gets to like 270 im only gettin 13 mpg everywhere cuz where i live there is a stop sign on every road

Dubl-A

Yea, I just got 494 this last tank...woohoo!!! Like I mentioned to my wife, this car isnt the most exciting off the line, but more fun with highway passing and such. without gunning it at every green really helps
