I get 250km to a tank on my XJ6N. Iv run out of fuel once at 272k's. F-trip comes on at about 220kms, and iv calculate iv got 50kms on reserve. But i fill up at 250kms, incase I've been riding hard this time round. When i ran out of fuel i was quite please when i realised my predicted range was only off by 2kms on the give side. But still stupid to let it run out, i was having a pretty shit day when it happened.
