hey guys
i'm in australia so our fuel ratings are different from say the US, but i was wondering if it is worthwhile in me putting "premium" (the higher of the two common fuels here in oz) fuel in my 1990 model DOHC galant?
would it give increased performance in any way? i'm aware it probably increases fuel economy but i was wondering if our car's ecu (or whatever) can make use of the higher octane fuel?
any advice?
