Change in the weather.

[JockoT]

We all know that fuel consumption is poorer in the winter than the summer, but after enjoying several weeks of warm, dry, early summer weather, this past week has seen temperatures here down by 10°C, with rain the past two days. What I have found is that the car is not getting anything like the mpg it was getting (going by ScanGauge E) when the temperatures were higher. My coasting points are all needing re-calibrated, as the car doesn't coast as freely (either in or out of gear) as it did when the weather was warmer. The joys of a Scottish summer!
