So last week I had a tonne of meeting sat work that were out on site. Because I am stupid and decided to buy an S3 to do 20k mpa I decided why not see if i can make a single tank of fuel last over 400 miles, I have been close before but never managed it. So after driving in efficiency mode at very slow speeds I managed to get 513 miles from a single tank. This was 70% motorway driving, 20% town driving and 10% commuting stop start traffic. I must say I was amazed at this. I should also note that this S3 is running APR stage 1 with the APR carbon intake, APR turbo muffler delete and a Milltek non res catback stsyem (not valved). Its proven its worth at 428bhp and 440lb/ft (high torque map). Do we have any challengers?
