With the price of fuel being what it is, the mileage you're getting is becoming more important. This is the place to discuss the mileage performance you're getting out int he real world.

This is something that is difficult to compare. I had an '02 Lexus Sport Cross. Drove pretty conservatively, kept the tires inflated, rarely went more that 5mph over any speed limit. Consistently saw 22-23mpg. Then I would read complaints on the IS300 SportCross board (not this site) that people (mostly young it seemed) were getting 16-18mpg and expected more. They also talked about how fast they could corner and what cars they could leave at stoplights. We've all read the lists of things a driver can do to improve gas mileage. Some people do those things, some don't. Point is "mileage will vary depending on driving style". Unless you ride with me you can't know my style and thus get a valid comparison.
One of the features of my Avant is the instant mpg readout on each of the trip computers. At 60mph I'll see 27-28 on level roads. Increase the speed to 75 and the mileage drops to 22-23. At 40 I'll see 29. Just one of the many variables that affect our economy (or lack thereof).

My mileage stinks. I tend to average 15 to 16 mpg when I do 50% hwy and 50% city. Locally only I get 13 to 14 MPG. I'm using Super Unleaded. Do you think something is wrong?

Since the Avant has a 3.2l engine it probably isn't comparable to the 2.7. My automatic runs under 1800 rpm most of the time. It is running in 5 gear around 32mph. Watch your tach to see what rpm you are turning around town. However 13 to 14mpg in town is what a pretty heavy 8 cylinder equipped SUV should get, not a 6 cylinder sedan or wagon. The usual things to check would be tire pressure, plugs or maybe a leak when the system is under pressure. Unless you are leaving parallel black tracks at every stoplight I would say something is wrong. Good luck finding the answer.

Since my last fill I have put on 270 miles, all in town driving. Not much stop and go, but all the miles driven under 50mph. Some stop lights, not much idling otherwise. What I find of interest is the trip computer for this tankful indicates the engine has been running for 11 hours. So I've averaged about 25mph and achieved 20mpg. I'll be putting about 55 miles on the Avant Monday and most of it will be hwy driving. Averages will probably go up some.

In their year-long 25K-mile long term test, the editors report having gotten 22 mpg with a 2005 A6 3.2
#7 of 16 Audi A6 2.7L "warm up period" ??
Jul 24, 2006 (7:14 am)
After sitting idle for 4 to 5 hours my 2003 Audi A6 2.7L Turbo (which I just bought in May) has to warm up for about 2 minutes. If you drive while "cold" car barely moves past 10-15 mph. Audi tells me this is normal but I'm wondering if others exeperience this.
Also I get 12-15 MPG around town and 22-23 on Highway. Local driving seems very low. Others experience same?

Seems absurd to me to think of that as normal. I had a VW turbo for over 100K miles and (despite being a cheaper cousin to your car and an older model year) started up and drove normally all year round without any specific warm-up time. I'd call again and not even seem open to "is this nornmal? line of conversation. Just "I need to bring car in, have you let it sit for 5 or 6 hours, then start it up and drive off and diagnose what's wrong. When I do it, the car will not run properly; is limited to under 20 mph." Geez, I feel angry for you!

Numbers put up by any car's "trip computer" are notoriously unreliable.
First fill your tank. Then, next time you fill up, divide the miles driven by the gallons you put in. That is real world mileage. Anything else is a guestimate.
#10 of 16 My numbers agree

Don't know where 150mph finds his data but my '06 A6 Avant's computer is always within .2mpg of my manual calculations when I fill her up. This is in the 22 to 24 mpg range. I have had the car 16 months and have 16,500 miles on the odo. The computer is less than 1% off (high). If every activity we encounter had an error rate less than 1% imagine how sweet life would be.
