last week i put 3/4 of Shell Vpower in the quattro... just over a week later im just on petrol light, got 220 miles on the trip averaging 21.7mpg!! i have replaced the breather hose and cant find any more obvious damaged pipes.... at my whits end it shouldnt be that bad?! its been town driving and the occasional 'Boot' but nothing major at all!! also, the third gear seems slugish... my friend has a mk5 fiesta zetec S and in third im not pulling away from it.... supposed to have 180bhp standard.... doesn't feel like i have anywhere near it!! any ideas to get me pointed in the correct direction please guys? Thanks!! Edit: does not have a map and is standard.
