gas mileage

[doug bergh <doug@devices.com>]

I have a '97 A6 Quattro wagon that I bought new just about a year ago.

Its EPA mileage estimates were 20mpg city, 26 highway.

I get between 16 and 19, with about an even mix of city and highway
driving.

Anyone else have a similar problem?

The dealer checked it and said everything was fine, they couldn't do
anything about it.

Any suggestions?  I drive very conservatively and have switched from
medium to high-octane gas to try to improve the mileage..  Is there an
optimal engine speed I should try to stay at?  It's an automatic but I
can shift it manually..

Thanks in advance for any info!
