Filled up today, and as expected the numbers were well down. 53.6 mpg. However, that is nowhere near as low as I was expecting. Yesterday I had a trip to and from Danderhall, and both ways the rain was coming down in biblical proportions. Traffic was heavy and in some spots very slow (I was down to 3rd ascending the Queensferry Crossing - quite a steep hill in either direction).
The calculated average for the last two tankfuls works out at 59.6 mpg, so perhaps my Asda top up last time was pretty accurate.
My Fuelly average for last 10 top ups has fallen to below 60 mpg, and I don't expect it to recover above 60 until next summer. I will be delighted if I can weather the winter without the 10 top up average falling below 55 mpg!
Also, funnily enough, 59.6 mpg!
