I cannot recall it being talked about although it may have been mentioned before, but who uses Spritmonitor website to calculate their fuel economy (mpg)? www.spritmonitor.de/en/ I do and enjoy using it; Scooty does also and possibly not just because its a German site. Its in English also so no need to get your Rosetta Stone out! It now has a smartphone app so you can plonk the details in at the petrol station and will give you the mpg once you synchronise, i.e upload the data. There are plenty of other Copens on there but I think it would be good if some more from this site joined in. Its better than flaming Candy Crush Saga!
