Yeah, did it before and have to call AA to fill up my tank, lol.
Depend on how you drive it imo. If i go highway after fill up, it will be about 70 ~ 100 km before the needle start going down, but if I got stuck in traffic jam or city traffic then after 40 ~ 50 km, the needle start to drop. Anw, it wouldn't bother me much, I just bother how many km i can go for the full tank, well not technically full tank but from full point to empty point on the fuel gauge.
Usually when the needle come to empty line, I fill it up and it only take 45l while the manual said 60l but I don't care much about that
