My V6 M6 in heavy traffic gets around 17 MPG. But that is about as bad as it gets. Driving around in the mountains yesterday and averaged about 25 MPG. Also I find that the computed MPG on the car is a tad low. Almost 2 MPG low. When I divide the miles by gallons used it is alway higher. Have yet to take a long hiway cruise. Seems like I will get the 29 MPG as advertised.

Just got that crapy 87 octane out of my SS from the dealer. But I got 20.69 mpg's which isn't bad after considering I have been showing the car to people and they just want to hear it run...

400 miles as of today. The DIC says 19.7 mpg. Not so bad I guess. I have not really exceeded 4000 rpm yet. We will see when I start letting it rip. My old LS2 Corvette was good for 25-30 on a trip but only about 20 around town with my type of driving. I do not granny it but it is a mix of cruising and some spirited driving!

DIC says 19.5 on the A6 SS with a mixture of driving on it with 600 miles on the odometer.

I'm at 2300 miles, SS manual
After about 1500 I reset my MPG gauge, to see what its like after break in...and its much better. During break-in I was at about 16 mpg. But now I'm getting about 17 city and up to 22 highway...for an average of about 19 MPG. Not bad, considering I drive pretty spiritedly. A very modest driver could easily be hitting 20-21 regularly..

L99 around town gets between 15 and 17 depending on my foot. The only time I had any amount of freeway I got in the mid 20's when taking it easy. My problem in town, is taking it easy. It only takes a few runs to kill your mileage. She can sip like a lady or guzzle like a bar queen.

2200 miles on my SS L99. The most MPG I've seen so far is 24.6 average on a 350 mile trip. The least I've gotten is 19.2 driving back and forth to work for a week (mix of county 55 mph roads and city streets). I'll probably get better when I break my addiction to romping on the gas now and then.

LOL I filled up today and reset everything. I was only going about two miles and the first mile was down hill. DIC showed 88MPG. If only I could go down hill everywhere.

2450 miles on my 2LT RS - averaging 22.5 mpg, 25% highway / 75% secondary roads. I have gone 407 miles on 18.150 gallons as the deepest I've gone into a tank -- considering it holds 18.8 gallons I was cutting it close (yes I know don't run out etc., etc.,)
I have found the Low Fuel Range pretty accurate indicating a little over 2 gallons left when the indicator comes on in the DIC, usually with about 44 miles as the reading before changing over to "Low Fuel Range".

I have just under 1K miles on mine, and I am at 26.3 mpg. That is 90% highway and 10% around town. When I filled up last time, I was just off of the highway, so I reset the DIC just to see what my mpg looked like with straight highway time. With a warm engine and averaging about 65 mph, the display showed 33 mpg. That quickly trailed off when I exited the highway and made my way through downtown to my office. I am pleasantly surprised, and after I change my oil this weekend, I will be interested to see what it looks like.
