Hi Dan, Thank you for your help regarding my Focus. I managed it in the end and rang John at Wincanton to thank him and explain. The Tunit is excellent; 65.5 mpg over 55 miles to Bristol at normal speeds and 63.5 mpg at normal speeds on the motorway to London the following day. Overall this is 8-10% better than before. Brilliant!
