I thought I was going to test what my car had to use … I was scared…I was full of fuel (until it shuts down) then drove 120 km and refueled again(until it shuts down on its own) then the view of the tank column wow said and wrote was there 23,04 liter ….I drove the car quite normally ..there’s something wrong… as it’s an Audi 80 Avant bj.93 150 HP VR6….maybe it’s due to the wide mature or the kat (which is empty). is)(am … I wasn’t that) would be great if someone could tell me something about it…
