How many kilometers can you drive with one tank of fuel?

Hey fellow car owners, what's your fuel consumption like? I got my new car on August 15th, so it's been a bit over two months now. My city fuel consumption is around 11.6 to 11.9, and that's in economy mode. On the highway, it can reach around 8.5. How about yours? I haven't done the first maintenance yet. Feel free to share your experiences!

What's the full tank range in kilometers?
