I'll do this in American-eese, since using KM's and liters seems to bring funny looks.
Distance: 1,340 miles
Time: ~21 hours in the car
Fuel: 48.35 gallons
Speed: 70-80 MPH on the highway
Mileage: 27.5 MPG.
And that's with a bum O2 sensor!
All I can say is I love my car. I'm used to driving 4 hours in the Forester and nearly falling out of the car from pain and stiffness. When I got home (at 6:15 AM today) I stood up, started to stretch, and realized I didn't have to.
Anyone drive farther than me?
