[K.P.]

I've never had a Falcon or derivative (non-turbo) not drive very well on 91, 95, or 98. AU Fairmont, AU Fairmont Ghia, and now FG XR6. I've never found 95 to be worth the cost vs performance gains as stated 3 weeks ago. 98, yes.

I drive on petrol regularly, not let the petrol side languish as too many dual-fuel car owners do. It never pays to.

I don't even understand your posts. I do, but relevance? Additive thread! Aren't you just being a sexist conservative trying to blame Julia Gillard for all and anything at any time petroleum-wise in the last 12 years it seems?

Not sure that Mobil Supreme 98+ is less economic than BP Ultimate now, seems about the same but better performing after checking today's drive.

I have to try Vortex 98 in this car, never used it in this one, it was decent in my last car but behind (slightly) V-Power (new additive package) and definitely behind BP Ultimate. I've only used Mobil Supreme 98+ just recently...top pick for me. Longevity? Unsure. V-Power is great short-term, 1-2 weeks then fades.
