I get from 18-20 mpg, this is calculated with the mileage/gallons at the pump. I don't pay any attention to the gauge in the car, the car meter is always much higher than calculating with mileage/gallons, what I pay is "real" mileage, haha.
I'm satisfied with the mileage I have now, I pump 1/2 tank of normal gas and half a tank of premium, so far no big difference in mileage and I don't flog it so no diff there either.

ive averaged almost exactly 17mpg over the ~16k miles ive driven the z. most of my driving is short trips under 10 miles.

why?

After 31,000miles;
Average 22.6MPG
Best 27.3MPG
Worst 18.9MPG

Distance per fill-up 382miles
Fuel cost $6199.30
Cost/mile (including service/tune-ups) $0.25/mile

6 MT At 19,000 miles
$.25/mile is what I spend on tires.

12 MPG daily average
26 MPG freeway best once
7-8 MPG at track usual

I gets 22mpg combined

Over the course of a weekend with the car, having fun and just cruising, my MPG tends to settle around 19 or 20. When im driving in-town stop go stop go, and the read timescale is short (like a few hours or a day) the lowest avg ive seen is 13-14. If im cruising on the highway for 25 miles, and i measure the MPG just for that drive, and i try to get the best MPG possible i can hit a max of 28 or 29.

i get about 20-22mpg average. i only drive on weekend mornings when traffic is usually light.

Last three fills-ups with varying amounts of highway/city driving ---

21.7, 23.2, 22.6

I usually average 18-21 (calculated at fill up) depending on how I drive the car that tank. I just road tripped the Z a couple weeks ago and averaged around 28mpg highway. I was mainly doing between 75-80mph, with some bursts to 100-110 because I couldn't resist.

I don't particularly care about MPG but am pleasantly surprised.

After about 25K miles of daily highway commute for the wife, the Z became my DD. She averaged around 21.5 mpg for the life of the car. My commute is city miles, but I avoid highway traffic by taking alternate side streets. For about 10K miles, I got no more than 18 mpg unless I was really trying to get good mileage - I struggled to get 300 miles on a tank filling up at least 17 gallons 95% of the time. I got an EcuTek tune in May and I've put over 5K miles on it since. I'm now getting 20 mpg on my daily commute and 350 miles per tank without trying (with the same fill up habits - 17+ gallons each time) When I take it out to have fun, I typically get 12-15 mpg.

I pump 1/2 regular and 1/2 93 - because I'm cheap.

Your tune sounds great. 12-15 MPG is certainly having fun too. :tup:

19-20 mpg. A7, 75% city, 25% freeway. Best of about 24 on the highway and worst of about 17 in town. Regardless of what car I drive I usually get whatever the EPA City Rating is (for that particular car) for my normal driving, my 2010 A7 Sport Package Z carried a city rating of 19 mpg so I am getting what I expected.

You realize you just saved $3 right?

6MT - 22.3ish on avg.

Before my exhaust it was about 24-25mpg. Can't figure out why a sweet sounding exhaust made it drop... :ugh:

:icon17:

Even if I baby it, I still get 22.5ish. I just drive like a grandma, and mainly highways.
