...last buy petrol? I know that there are some on here who don't own a car, but there are also some who do a bit of both cycling and driving (myself included). So, 'fess up - when did you last fill up? I filled up just over a week ago. Probably about due again in about another week. This was a full tank on a 1.4 X-reg Polo. That's about average for me - once every two weeks. Am aiming to knock at least a week off if I can. Would LOVE to hit once a month (still need car for shopping and longer hauls etc.) if I can.
