Me, I like Texaco. :} You can't go wrong by following the recommendations for octane given in the owner's manual, but despite what it says, I think premium gas is unnecessary (unless you have modified the engine). The DeLorean has a low compression engine which is by its nature not prone to knock. If you hear knocking regularly, you need higher octane. I don't know the octane availability in Australia, but anything over 90 is probably adequate.
