Hello,

Just picked up a 2018 q7 with the 3.0 supercharged v6, the manuel states it has an 85 L tank or 22.5 Gal. I had my range all the way down to zero and still drop about 10 kms on it , after filling up full, i managed to get only 78 litres in. Im getting about 11.6 litres/ 100km average. Is there 7 litres in reserve left? Any input is appreciated
