Nürnburgring Fuel consumption….

Question Been eating oil on weekends in half Germany (Kleve (near Holland) Nürburgring, Münster and always back in Bielefeld !) So about 1200 Km on our highways. When I drove from “Kleve” back to Bielefeld it was 2 o’clock at night! Only to Streken-info A3 to Oberhausen …A2 …Bielefeld so about 220 Km a track Kleve – Bielefeld . on the whole track were possibly 50 – 70 cars no trucks ́s Saturday on Sunday 2 o’clock at night stop. I could and also drove full throttle all the time. And if I “full throttle” say it was also “full throttle” had only to brake so empty for construction sites it was! Now comes on, in Gütersloh went on one time my reserve lamp. When I was in Bielefeld tanks 45L went on…* swallowing* So 230 Km 45L = good 20L consumption. otherwise I drive it also between 9 and 11 liters … I mean that my sadness is also high record over 20L Super lead-free (95roz) at 1.5 hours without interruption would be so much more than the ring.
