1989 BMW 318i Coupe
When all I do is drive to the station and back for a few weeks (about a 5 minute trip), I get about 280km before I feel the need to fill it up. I never let it run down though, I'm a bit of a wuss when it comes to petrol. I'm not interested in seeing how far under the "E" line I can get, and I don't know if the low fuel light even works. For that matter, I'm not 100% sure I've got one. I actually think I've still fot at least of a 1/3rd of tank to go when I fill up, I always fill it, and I rarely put more than $25 in it.
When I do "proper" driving though, I can go close to 400km on the same amount, and when I took it to Adelaide it went close to 450-500.
It's a bit small though.
