I refueled twice at a gas station with diesel on the 6th column with an interval of half a year and twice as if I refueled with air, when checking it seems OK, but in fact some kind of deception. I thought the sensor was buggy, it turned out everything was OK with it, the next day I refueled for another and in winter everything was fine. You won 't be able to prove it, so if you stop by Judas, you'll just lose money.
