All castrol oil available in Australia is made in Malaysia except their Edge FST 5W30 VW504/507 oil (Europe somewhere) and this, their new Bio-Synthetic Magnetec blend (Thailand.)
I've not used it, Just saw it in the local parts store on the weekend and thought it was worth putting up here for discussion. Looks like it almost classifies as a mid saps oil (0.81%, so close but not quite.)
Keen to hear your thoughts
