Can be quite variable depending upon driving conditions....I'm driving on guestimate about 60/40 city/highway, and I'm getting around 22-24 a gallon.....If I drive on the highway I can top out around 29-30.....

I'm doing great! 23.5 mpg !! Mostly canyon driving, not really city and not really highway, but it's been raining a lot and I haven't really been pushing it much... yet.

I average about 20, but on a drive from Buffalo to DC I got just under 30 on the highway, and I wasn't exactly taking it easy.

On a related note:

I recently moved. I used to have about a 3 mile commute each way on suburban roads, stop and go traffic most of the way. I now have a 17 mile commute each way, with most of that on the highway.

Before I would go home for lunch, so I made that round trip twice, about 12 miles a day, and now I've got about a 35 mile round trip.

I've found that I'm not really filling my turbocharged Jetta much more than I used to even with the huge increase in mileage. I used to fill weekly, and now I probably fill maybe one more time per month. The car gets great mileage on the highway - off boost - and is an absolute pig in stop and go - on boost.

Something to think about if you're considering a turbocharged car...

too low!
damn gas went up again. $2.77
$30 got me 3/4's full.

(yeah I'know other's have it worse but you should see how much I pay in car insurance and NYC parking and these toll roads are getting ridiculuous)

When the weather is cold I get about 20-22 mpg. I tend to short shift and go easy on my cold tires until I'm at 180 temp.

When the weather is nice and the top is down I drive fast and hang out in third gear like its a long lost friend. 17 mpg.

I got less than 20 mpg around town before my new 02 sensors. Now I get about 23 mph in town and over 25 on my "road trips" to the country where I hammer it the whole time. Go figure.

If your boxster has 60k on it, replace your 02 sensors before they go out and throw a CE light... you'll be glad you did and enjoy the fuel savings as well.

I believe performance went up too after I changed them, but that's just my butt dyno.

OBC says 25-26.5 in normal (95% open road) driving. Almost no stop-n-go. Regular but not constant trips to redline in lower gears,

Got almost 30 on mostly Interstate trip to Tampa area and back in Dec 05 @ 80 mph average.

Early months 22+ mpg until broken in.

I was getting about 23-24 on my daily driving and 30 on my long highway trips and I was getting a shudder sometimes as the car reved down to idle....I called the dealer service group and was told that my mileage was "too good" and that I should drive the car harder...more 3.5 to 4+k plus shifts. Well sure enough my city mileage went down to about 22 and the highway stayed at 30 and the shuddering is drasticly reduced....can only assume that my city driving was "clogging" the system. Only about 8500 miles on the car to date....bought the car with 3500 miles on it 5 months ago...must have benn someones weekend car but is now driven daily. Very happy I have a 100k CPO warranty!

I drive about 10 miles per day back and forth to work... probably 50 or so on the weekends. I fill up every 220 miles or so. So do the math.... What is it 14 gal per tank divided by 220 miles.. roughly 16 mpg around town.

I think the important question is how much are we spending per mile. 1 tank of super is 37.00 here in NJ divided by 220 miles for that tank = 16.81 cents per mile!

I wonder what our buddies in the Hummers are spending per mile....
