Thanks, where does the Average MPG get its info from? Is there a chance of a blockage if its a vacuum hose?

There is no fuel leak, yes i think its over fuelling. Question is what is causing it?

Hi I have a 2008 Foreste with a 2l petrol engine. The average MPG has just dropped significantly. I was getting around 28 around town, but over the past week it has been dropping and yesterday it dropped a lot. Showing 11-13 mpg this morning. I have been to a garage and (despite there being no engine management light on) they have hooked it up to the computer and found no fault codes.? Can anyone offer serious advice on what to try? I have no external leak of fuel or air.
