I have noticed over the past 2 months that the MPG on my 2007 1.8 petrol manual focus has been dropping on a weekly basis.
Was getting about 36mpg, then dropped to 34mpg now only getting about 30mpg.
Same journey every day, dual carriage way keeping well within the national speed limit.
Any ideas why this would suddenly happen?
Sounds normal to me. As the weather gets colder the car takes longer to warm up and consequently will be on a rich fuel/air mixture for longer.
sensible explanation from IMW. the other possible reason might be a change in quality of petrol. I have noticed that my car perform better with higher mpg on shell normal unleaded than the supermarket petrol.
