I've got a 2005 987 and on the highway cruising at about 115km/h I can get somewhere in the range of 750-800km on a full tank. I've never actually let it go down to empty but I made almost 600km (Toronto to Montreal) on 3/4 tank. This is about 30mpg or 7.8 l/100km. The gauge seems to be fairly linear (ie about 100km travelled for each 1/8 tank, 400km for 1/2 tank, etc).

All this was with Esso 91 octane gas. I've started using Sunoco 94 octane but things don't seem to have changed too much as far as fuel economy is concerned.

In the city is another story, however. I'm getting somewhere in the range of 15-20mpg, sometimes less.
