Just come back from the petrol station, before I filled up the fuel gauge was just below the 1/4 tank line, filled up £ 40 of Octane 99 and the indicator went up between the half and 2/3 of a tank line, after 5 min drive I got home and the indicator went up a bit more towards the 2/3 of a tank line.
Is this normall? but more importantly, is that all I get with £ 40?
I tought that because I stiil had 1/3 of a tank £40 would have filled up the tank
