Classic Chevy Centre in Sydney 02 96097228 keep it in stock and I think even Holden may sell it ?
I can recommend changing fluid first with Castrol LSX90 before using additive, you may not need it ?

Might give this Castrol LSX90 a try, cheers.

Any additive will do pretty much.... Torco seems to work the best!
