Ahem.... that was a typo.
Now 23.3. Whoopie-Do!
I've done about 20,000 miles at '23.1', so for the miles since the repair to have built that average mpg up to '23.3' I reckon the car might be doing 24 mpg????
Who cares. It shows the car goes better (faster/ better mpg) with them working.
I love the S8, but them fill ups r hurtin!
