my work has been running out of ultimate on some tanks but not others and we always have premium.. the government took the rebate off petrol which is why its 13c more then regular unleaded not 11c.. I've heard a rumour that BP has been running out because they dont have their own depot (could possibly be only in newcastle) and we share shells depot and they're giving us trouble lol ... I'm not sure if thats 100% why they're running out but its definatly a reason..
I have heaps of skyline owners come in and used regular ethanol unleaded in their cars lol I cringe of course but couldnt be too bad for it in an emergency
