I was low on petrol (my computer said I had 70 miles left) so put £8 in. I'd say that's about 50 miles worth of fuel so would have expected the computer to have informed me I now have around 120 miles left, but instead it was unchanged. The needle on the fuel guage hadn't moved either seemingly. So I either got no fuel from the pump (if so I was lucky I didn;t put much in because I doubt they'll reimburse me my money) even though the pump counter was spinning (unlikely) or there is a problem with the computer (more likely imo). Its not stuck/frozen because it decreased to 69 miles as I continued on my way as I wondered whether to raise the matter with the petrol station or not.

Is this something known about with Civics and their computers? I've not had mine for long (3 months) and I've not had this issue in that time up to today.
