There are still a lot of unanswered questions about the sulphuric petrol that left hundreds of road users with empty tanks.
Low quality 91 and 95 octane gas caused the issue but the fuel companies said it was only sold between Novemeber and December last year. Now it seems the petrol was more widely distributed than first thought and affected more vehcile types.
