Hi,
Still doesn't make sense, seems more that something is calculated wrong.
I have been using the UK link thanks, but on my fuel up stats under Log Book it says "UK MPG" and I have two results, 25.2 and 24.6. My car has never managed 30+mpg that I know of.
Anyway my badge shows 31.6 UK mpg. I believe my partial fuel up hasn't been accounted for properly.
If I do the calculations myself I get 21.16mpg and 24.57mpg (both UK), so the log book is wrong, but the badge is way out.
I think there is something wrong with your script, like it's doing a US to UK conversion on my UK mpg data?
Anyway it's making my car club think I drive like an old lady
Thank you for the quick response, and great site, really like it thank you
