Hey
Just got a 05 S Chilli 3 weeks ago. Last time I filled up on fuel the range on the computer said 490 kilometers (305 miles). I managed to get 420 kilometers (260 miles) out off the full tank after some light heavy driving.

Tonight after I filled up (to a full tank) it said 410 kilometers (255 miles) on the range. Really quite weird.

Any ideas and could you tell me what sort of range you get out of a tank.

thank you very much
