Fuel consumption EC3 positively surprised

I bought the EK3 Limo on 23.02 for 1300.- so far good condition service all made, almost full tank only 80 km from the previous owner still driven since the refueling. I needed an acclimatization phase because with my former EJ9 the clutch was fast and now at the EK3 rather late. so the first time filled > 334 km > 23.82 > 7.13 l/100 km. I thought ok there was still a little bit of what after I had kicked it on the AB times correctly, did not know how the predecessor still drove the 80 km. The clutch also makes no problems again so wait. I missed a new air filter in the meantime. Now yesterday I had to fill my new used EK3 Limo again properly again since the purchase, and was very surprised about the low fuel consumption with quite sporty driving way city and country road > 586 km> 34.36 l> 5.86 l/100 km. had before the EJ9 Limo and which was in average with 6.5 liter of gasoline, my fazit > 24 HP is now more efficient and more efficient for the top class.
