i'm with DanielGTST on this. WA has better fuel than the rest of Australia, lucky for us bad for you guys. WA has very strict regulations for the fuel and emissions caused by it. Thats why all WA petrol is made in the Kwinana refinery to the boutique standards we have. We don't get Shell Optimax here as it doesn't meet the guildines. This is something the news articale should of pointed out if it was thourough.
