During a road trip my OBC read 511 miles until empty for about 15 minutes after I filled up, then I actually started driving and it decreased to about 320. But my average mileage on a tank is about 280, which seems normal, and much better than some other sports cars.

15 mpg here. My commute is 2 miles every day, and the fact my engine never warms up shows 
Also think bad O2 sensors are not helping, I'm wondering how much it'll help when I replace them.

Mine are Imperial Gallons not US, but they are close.
Best 31.5 on a 400 mile trip
Worst 9.1 on a track event
$3.50 a gallon, I wish. Its 1.05 GBP for a litre of Shell Vmax (99 RON), 4.54 L to a UK Gallon equals 4.55 GBP per gallon which at exchange rate of 2.05 is 9.77US per gallon. The kicker is that most of this is tax.
I am going to do a Thelma and Louise now

David, this has got to be a major killer for a car...especially our Boxsters. You need to find a longer way to work!

Tool Pants, I'm trying to figure out where the half-mile-long hill is near San Jose.
One our first road trip with my wife, I got 26 mpg. A month later, on a trip alone, I got 29 mpg. What is Porsche trying to tell me?

I thought you might find this interesting, there is a great EPA website that keeps track of mileage estimates for different cars.
EPA Website
Check out the city/highway mileage estimates and hp for the base Boxster with manual trans.
2000 19/27 217 hp
2003 20/29 228 hp
2005 20/29 240 hp
2007 23/32 245 hp
Interesting, I want 32 mpg with 245 hp, thank you very much.....

So I had to run to Florida to visit family this week and they have a Porsche dealership in Melbourne Beach. Stopped in to test drive a 2003 Boxster S (just playing, not interested in buying) and noticed that they had a base 2008 that listed 27 mpg for the highway (not the 32 mpg Porsche had originally given for the 2.7L engine) on the window sticker. I guess that reflects the new EPA method for estimating the mileage.

bmussatti said:"I get about 20-24 MPG. Top down, Sport Chrono on, and spirited driving."
That is way better than I get with the same car. I also have a 2006 S and consistently get only 18 mpg for my 12 mile trip to town, which is half highway and half traffic. I'm trusting the readout for this; maybe I should check it the old fashioned way.

I drove 1500 miles this week, almost all highway. I traveled very consistantly at 78 mph. I first went through a tank of gas with the top up and got 28 mpg (its painful to drive 300+ miles with the top up). I then went through a tank of gas with the top down and got 25 mpg.
I dont have a computer in the car to give readouts on mileage at different speeds. For those of you that do, what highway speed gives the best mpg? I am wondering what I would get if I drove, say 60 or 65 mph on the highway. Its never going to happen, I was just wondering.

bmussatti mileage
Dear bmussatti,
you said:"I get about 20-24 MPG. Top down, Sport Chrono on, and spirited driving."
As I said, I only get 18mpg based on the readout with the same car. Under "settings - consumption" I have selected "miles/gal." But there is setting called "mpg UK"; if yours was set to this - the larger Imperial gallon - that would explain your better milage. Can you check?
