2000 S 3.2L w/31K miles; 30K service pending

I drive it ultra-conservatively with a round trip daily of 20 miles and usually get 16-17 MPG... this equates getting 230-250 miles on tank of gas.

On straight highway driving, I get 27-28 MPG and get close to 350 miles on a tank of gas.

I always reset the trip computer at each fill up and will always calculate MPGs by miles driven/gallons with calculator to compare the computer. The computer always reads ~1 MPG higher. The values posted above are the lower, hand calculated MPGs.

I'm hoping for some improvement once I complete the 30K service.

i cant remember where i red this.. some magazine i think, but the article was a write up on efficient engines. they praised porsche for making the most efficient engine that runs on premium gas. they tested the new 911 that is, whose engine is much different than many of our older boxsters, but still porsche product

I have a 2008 with 1,800 miles on it. If the car's computer is right, I am averaging 15.8 mpg. I do mostly city driving with an occasional trip on the highway. Last tank of gas I got I went about 250 miles on, but I didn't wait until it was really close to empty to refill.

I average a little over 350 miles per tank or a little over 28mpg. 2.5liter engine.

I used to get 22 - 23 mpg driving somewhat conservatively, but now I almost always keep the rpm's over 4000 and i'm between 19 and 20 mpg(but its a lot more fun).

MY 2001 base (2.7l).

I got 29.4mpg on a trip to Yosemite and back. Lots of twisties, reasonable speed most times, top down 90% of the time.

Then, took a trip to Lake Tahoe and back. 29.8mpg. Lots of fast sweeping curves, high speed and all, top up 20% of the time (high speed + wind causing windscreen flutter).

Low traffic during both the trips (drove mostly on weekdays).
