I recently purchased a leon fr tfsi 2.0 petrol on a 2007 plate. Out of a full tank of shell v power which costs around £62 from empty the most miles i have achieved are 270 and thats with 70% slow driving but its always short local runs. Its weird how people who drive 4.2 litre petrol cars can get 400 miles plus for a full tank. Can everyone please post how much petrol costs them and how many miles they get. Thanks
