The nights have turned cooler here, hanging out around the freezing mark for a low temp, so by the time I get out of work to head home at 23:00, it's a struggle to get good FE. Considering putting my "grille block" (one side of a cardboard box which nestles nicely behind the grille) back in tonight. Having said that, I am hoping I can pull out a 40mpg performance tonight.
I have decided to set my next goal as getting under 6l/100km, about 39,27mpg.
