Did some testing on A6. Filled up 3 weeks ago and low fuel light came on this morning driving back from work. The tank is 70l and reserve is 12l so I have used 58l and done 435 miles with it mostly on short trips, cold starts, demisting ect. This includes 15 return trips to work 7.5 miles each way with cold starts giving 225 miles, one longer trip 40 miles each way and rest local runs to shops, mates ect.

58l=12.75 gallons so it works out 34.1mpg. Trip computer shows 33.8 so not too far off.
In the past I have seen 48.9mpg average on dash on a 160 mile run but this was not verified however trip computer seems fairly accurate even a bit pessimistic.
