My experience has been the same. Don't worry -- it's normal. I had to add one liter at 800 miles (1300km), and another at 1500 miles (2400km). Right now I'm at 7800 miles (12500km), and am adding about a liter of oil every 1200 miles (1 liter per 2000km or so).
As far as fuel consumption goes, I'm averaging about 14 miles/gallon. That's about 6.0km/liter, so you're actually getting a bit better than me
Gas consumption has remained steady as long as I've had the car (well, it uses more when I drive more agressively, of course), and oil consumption has been declining.
