Fuel Economy

tdd1986 · 08-15-2010, 06:17 PM

Hey all I was just wondering what kind fuel economy you get out of Z.

When driving on the highway I noticed I get around 22-25.4 mpg on the meter driving on the highway. That is low in my opinion when the car is rated at 26mpg. Do you have any tips on how to improve fuel economy on city and highway driving??

I also notice that once i take the car past 80mph and keep applying the gas there is a very subtle kinda like a whistling sound (almost like the sound of a commercial plane revving up to fly but quieter) from the engine is that normal???

I am going to blame your location for the poor gas mileage.

Roger that. Hard to get a good air to fuel ratio when there is no air.

Ok, on serious note, are you complaining about 25.4 MPG? You think nissan (or EPA) cheated you out of .6 MPG? If you can shift at 2000 rpm (and don't rev above 4000 rpm) and drive at 65 MPH on highway , i'm sure you'll get that 26 MPG. I know members reported up to 29 MPG when they were driving on the highway. You mpg depends on your driving habit. I'm lucky if I get 16 MPG!

I have no clue what you mean by the whistling sound. Maybe it's air thats hitting your side mirrors at 80+ mph?

Hahahaha i gotta move back to earth damn this red rock!!

Do you hear any hissing noise at all in ur smurf mobile AK? sounds kinda like an electric motor in an electric car revving every time you apply gas past 80mph. you have to shut off the radio and close the windows to hear it lol

on my 7AT, cruising at 63/64, I can get 31mpg by the meter. This is of course in flat Indiana though.

There is only one smurf on this board, and it's not AK's

I have no idea what this whistling noise is though. But for the record, I get about 27 mpg with a mix of stop and go traffic / freeway.

You just might be the only one doing 63/64 in Indiana. I do 74/75 and get passed regularly.

I have gotten 26.3mpg with an average speed of 72mph.

Mixed driving has been closer to 20. I'm sure once my Berk CBE gets installed it'll be closer to 16.

While driving back from WV, I averaged just over 26 mpg (all highway miles), at about 67 mph.. That's right about where I expected it to fall.

Just drove from suburban PGH to suburban Washington DC and back---almost all gentle highway cruising. Air was on much of the trip, 2 passengers w light luggage load. With cruise control set to an almost constant 67 mph (except for road construction areas), my 7speed automatic (now nicely broken in at 3490 miles) got me 30.9 mpg, door to door. I'm very pleased.

x2

We get 32+ mpg cruising at an average 63 mph on a 2010 7AT. It helps being in manual mode, though, so it stays in 7th gear with full lock up 100% of the time.

i use the gas cubby ap for iphone. you enter your mileage of your car every fill up, and how many gallons /cost per gallon and some other info. long story short it tells you your avg fuel eceonomy overall. i get 19.1 with 50/50 city/highway. i'm content with that. my altima i got 24 mpg overall. 5 mpg less for much better performance and all around car. the way i see it is. if i have a car that slurps 93 octane gas i shouldn't be overly concerned with mpg.
