I got my coupe about two weeks ago and i wasnt expecting great mileage but 10 mpg in the ciy is crazy! i kno some of you guy's are getting 16-17mpg in the city and being that 90% of my driving is city, im putting out 70$ a week! any sugestions?

1. put skates on the car.

2. push car down street.

lol ok, besides those two great options...any real sugestions! come on lol

My sedan with 12K on it get's an average of 16mpg that's 80% city 20% highway, get used to it cuz its not changing. I shell out ~$65 every 4-5 days to fill up.

Your gonna get the worst mileage on a brand new car... once your motor breaks in youll see a slight increase in MPG

break in? i got 14k miles ..so that cant b it..

actually when my car was brand new i got 465 miles outta the first tank with 100% freeway, now i'm lucky if i can get 320 with all highway driving.

My G burned a lot of gas too. I use to get about 220mi on a tank, but I brought it back to the dealer for the tsb on the gas tank and I'm still on the same tank of gas with a lil less than 1/2 tank with 210miles on it. I dont know if this tsb performed solved my gas problem

10mpg is horrible. I have never gotten worst then 14.3mpg and thats with hard driving in the city.

Dont press on the pedal so much. On average, i used to only make lets say 260-280 miles with a mix of highway and city miles...mostly city. Since gas has gone up so much, i try not to be on the pedal unless necessary. Now i average 350-360 a tank. Its been easier for me to monitor my mileage since the navi shows you how much gas you burn based on how much you press the pedal. Some other suggestions...make sure your filiters are clean, check your tire pressure, change your oil

If you haven't changed your air filter yet I suggest you do.
I installed a Stillen CAI a few days ago and the OEM filter that originally came with the car was FILTHY. I asked a Infiniti Tech what was the life expectancy of the air filter. He said 15K miles and I'm currently at 10,500.

tire preasure is fine, no navi here , and even wen i drive like grandma believe it or not, it changes NOTHING, would the air filter really be dirty, only 12k miles?

i guess im gonna start with changing the filter then! thanks bro

I do a mix of driving in my 05 coupe speed..i have 2800 miles on it now. factory computer tells me im getting 20.9 miles to the gallon.. im not complaining im happy... very happy. i run premium gas and i dont drive like an old lady either...

a z-tube will get you 1- 1.5 mpg better
