I get about 43-44mpg out of mine, when I first got it a year ago it was really low I’m guessing the owner before me had been doing short journeys but she’s racked up 48,000 miles in 3 years lol I’ve done 8,000 miles in the last year. Mine is a 15reg 1.0 ecoboost. I really regret getting an ecoboost given all their problems and check the coolant regularly and have had to have a new seal on the tank at £75 as it was missing meaning I was losing coolant
