I also write my fuel ups in a log book as well as using fuelio. I realised that I must have forgot to tell fuelio about a previous fill up, but I have the litres written down in the log book. Its a pity there's no feature to alter fuelio fill ups so I can re-balance the stats with my log book written fuel consumption. I have a big dip in the charts at the time of missing the fuelio fill up. If I could alter the kms on the missed fill up, I could re-balance the whole of the stats. Never mind, that's life.
