I hope you didn't buy a Z expecting amazing MPG. They're sports cars. If it were a Prius and you get 8PMG, I'd freak out. Even so, I'd check for leaks, etc. 8 is low, but not too low for what you should be getting.

 

You should gut out your interior, get carbon fiber parts, and lose a little bit of weight. With all that... you should boost your MPG levels to around 19.

 

or do some "tune-up" maintenance. reset your ECU. unless you are flooring it constantly and maintaining your rpms above 5k at all times, your mileage should NOT be that low...

 

well the mileage is also relative to your avg speed

so if youre stuck in traffic for 30 mins, its easy to see an avg of 5 mph. in which case, a below 10 mpg is understandable

 

I get ~15 with my '07 AT 100% city driving. It can go up if I putt around like a grandma, but even then once in a while I open her up and ruin my mpg again.

 

check your car cuz that seems very low i get about 18-20 and im driving it alrite ur prolly flooring it or somthing

 

somethings wrong or you drive way to hard. I get 22.5 50/50 highway and city even with 100 degree heat with the a/c on. Going to school all highway i get around 25 to 26.

 

check your air and fuel filters

 

I was getting @18 - avg speed @25mph...

Driving a little more sedately (after the speeding ticket) - getting @19.5 - avg speed 30mph after changing route to work....

 

+1 On the high way I get between 22-26 mpg.......depends on speed limit I run about 10 over

 

i get 14-20 in the city depending on traffic

 

By the way - my '09 Murano just averaged 25.4mpg on a trip from TX <-> NJ. Mostly highway. Mostly at 80mph I was fairly impressed.


Better yes - it has been getting @20 in the city. That CVT is pretty interesting - and efficient...

 

That's strange.
I get about 27-28mpg on highway.
But in the city 15mpg/20mph average and I mostly avoid trafficlights.

Dirty air intake?

I'm not expecting amazing mpg - but it is strange (too good for highway and too bad for city).
