When mine drops by 3 bars it gets topped up. It costs, on average about £20 to refill it. I do this for no particular reason, other than I like to keep a full tank. I could cite the recent fuel shortages, the impending price rises in fuel, or the fact that having always owned classic motorbikes it was wise to keep the tank full to avoid the vacant spaces rusting.... but none of these really worry me unduly. It is probably because at the drop of a hat, we will venture off into the Dales, Lakes or Moors for a few days. So, we're starting full from the get go.
