I know no-one really cares, me included, but was just wondering what sort of MPG others get out of their S6's, i've got to fill up today and have done a whole 400 miles on almost 2 tanks of fuel (150 litres or so)
On the way to Germany I filled up twice (actually 3 times but only ever 25-30l, worried after changing from Griff), and did a total 900miles.. cruised at a constant 70-80mph.. so thats about 36mpg!!!
