Not that much... I know I tend to hold for a long period of time in 4~5k but not @ 7500 for sure.

If you want to know actual mileage, fill up the tank, drive, fill up tank, divide miles by gas=mileage. Don't use the gauge as your true numbers.
It sounds to me like the gauge was reset somewhere in the middle of a tank anyway. You'd have to work VERY hard to get mileage that low.

You would have to floor it every where to get 13, that mileage is just awful

Did you sit with the car idling a lot? That would hurt your mpg.

I started at 11 and now with 3500 miles I'm at around 19. It is what it is

Not idle but I do live in Los Angeles so constant break and gas.

So it's not unsual to start with low MPG and improve... That a relief.

ya it's the motor getting loose.

im making 450hp and when i beat on it i get a min of 16 mpg avg. so ya your good.

No, he lives in Los Angeles. Stop and go, stop and go, stop and go.

Prior to my tune, that was the same MPG I was getting. I'm up around 14 MPG since then.

It does get much better once you get out of LA.

^^^ that's really low even for stop-and go traffic... granted I don't live in LA... but I cross 17 miles Commercial which is a parking lot, and still manage 15-16mph.

15-16 mpg or mph?

Since the Z has a mph meter, I can see what my average speed is, and it rarely gets above 16 or 17 mph in my daily driving. Keep in mind that you're burning fuel when you are stopped, which is quite often in LA. I could certainly drive the car like a granny and get better mpg, but I also don't drive like a maniac... most of the time I shift between 3-4k rpm.

Yeah... I lived in Burbank for 3 years then moved out to Korea Town. Horrible traffic and bad drivers. lol

Burbank has better roads with less potholes too.

bro i live in downtown los angeles...and i take the 10 fwy to and back from school...I average waaaayy better that 11~12 mpg, but then again i also have a manual...but you situation sounds shitty- sorry to hear

11 to 12 was my very first tank of gas. 16to 17 after and since I stared this thread Ive been driving auto mode and now average 18~19

Lucky bastard... Korean women are one of my faves, I can't imagine being surrounded by them 24/7 :yum:

I get much better mileage on the freeway... if it's really flowing well, it gets closer to 20 mpg.
