I have purchased Hero Honda achiever in April 2012. That that time I used to get an average of 51-52 kmpl in local and 57-60 kmpl on highway. But after 1 year, I lost that mileage and now in Feb 2014, I receive a mileage of 40-43 kmpl in local and 47-49 on highway.
Its not that satisfactory. It shows company has made this engine for a mileage only for 1 year.
