500 miles to the tank is not all that difficult to achieve. With an approximately 9.2 gallon tank (Honda's official figure for the Mk 1) you need only get 55 mpg, and and at this time of the year I can do that standing on my head (not on the brakes I might add). Today I did a trip into town, shopping, my usual trip over to the south of Edinburgh, a trip to the shops while there, a return trip, then hit the supermarket here in Kirkcaldy. According to my ScanGauge I got 61.3 mpg for the day.
