wasup guys, i gotta 05 base model 350z. My MPG meter has never gone past 16.9 mpg!! idk why, and yes i have tested it by not driving fast and staying under 3k rpms. And still . . . . nothin. I cant understand how some of u guys get even 25mpg. Could there be something wrong with my Z?! All opinions welcome.

 

there must be... i drive like a maniac and still have 18+ all the time

 

24mpg, driving like an old man here.

 

idk man, im goin to take it to the dealer this tuesday cause i got that problem with the axle clicking, so im gonna tell them to check that out with the gas cause seriously, its killing my pockets Also, i put like $60 to fill up, is that about right?

 

I get 22.6 normal driving, 20.6 when I beat her senseless... I have never gone beloe 19.5mpg.

 

How many miles, pull of your air filter cover and look inside for a restriction or really dirty air cleaner. Just an idea!

Avg. 20.9 MPG with spirited driving.

 

Hmm.. I'm assuming you know how to reset the mpg meter, right? If you have been resetting it and still can't get over 16.9mpg I would say either your mpg meter is wrong, or you really are getting lousy gas mileage. You can confirm either by manually calculating how many mpg yourself.

 

I'm getting 17mpg but I'm still on break in so I thought maybe that was why?

 

If you only make short drives then your MPG is going to suck... My office is only like 2 miles from my house and I only get 12.6 mpg on my FX35 during the week driving back and forth from work, but if I do a lot of driving around town It goes up into the 17's and on highway I get over 25 MPG..

 

my Z gets 21 mpg city/hwy and 29-31 hwy.

 

how many miles do you get to the tank? my last fill up i got 320 miles, and that was with a night of racing.

 

Have you checked your tire pressure lately?

 

Your not the only one! But I have some perf mods and drive pretty spirited.

 

i get 20 on avg. and reset the gauge every time i fill up

 

I got 24 mpg on my first tank and 23 on my second tank. I do about 50/50 city highway. I got 29 mpg on a 60 mile trip one day, pretty much all highway

 

Welcome. The top number (MPG) is worthless without telling us the bottom number (average MPH). Give us some data to review:

MPG at 40mph?
MPG at 50mph?
MPG at 60mph?

 

My MPG stayed at around 16.4 when I first got the car two weeks ago (22 MPH average). I reset it at my last fillup and now I am getting 19.6 MPG with 23 MPH average. My driving is about 80/20 city/highway.

 

2.5 mile commute and same type of deal with my Z. More like 15-16 mph, but just starting the car takes a decent amount of miles to get over the warm-up burn rate. If you don't drive those extra miles, and top it off by driving it hard, well, mpg will suck. On those occasions I do some highway driving the mileage reponds accordingly. OP, you haven't said how you drive it, so I don't think anyone here can tell you if what you see is expected or not.

 

^^ Same here, 4.5 mile commute and very little to no highway driving. 15-16 mpg

 

But what is your actual gas mileage?

Fill your tank and zero the odometer. Also zero out the electronic display Next time you fill up, divide the gallons (on the pump) into the mileage (on the odometer).

Now compare the actual (measured) MPG to the number on the display.
