The way I understand it, and correct me if I'm wrong, but almost all petrol sold in Victoria comes from either Shell in Geelong, or Mobil in Altona. Even BP and Caltex - they have it made by the others to their specification. The same apparently goes for Sydney where they have a Caltex refinery (what others?) and BP in WA. This saves on the considerable cost of interstate freight.
This still doesn't explain why the two types. If 98 is only available by BP in WA, that might be explained because BP doesn't want to make 98 for its rivals. But, is 98 available at ALL BP outlets in WA (I think not)? If 95 is available at BP outlets in WA, why? Why not just make 98? This is still a question that nobody in the fuel industry (and admitedly my contacts are basically restricted to media reps) has been able or willing to answer.
Consider this - we are told by both BP and Shell that 98 octane is better for our cars and better for the environment, has less carcnogenic Benzine and other aromatics than lower octane fuel and provides better fuel economy. So, again, why sell 95 as well?
As for the economy test on ACA - I think it was run under fairly dubious paramters anyway.
I recently attended a media re-launch for "new improved" BP Ultimate. Nobody at the launch, even one of the top engineering guys, could explain to me how Ultimate had been improved over what it was before. Apart from the new, more visible signage and a bit of a vague mention about "new detergents" for more effecient engine cleaning, I couldn't find any eveidence that it had actually changed.
All the performance and economy testing had been carried out under very strict and exhaustive criteria (which I believe) and showed all the improvements of using Ultimate over 91 octane fuel. It was all very impressive and above board.
But, when I asked what similar studies between Ultimate and 95 octane petrol were available, I was told that no such comparisons had been done. When I enquired why BP was still marketing 95 octane petrol, if Ultimate was so good, I got no reply, and found myself suddenly unable to talk to any of the engineers. Hmmm.............
In terms of environmentally friendly fuels - well, no petrol is that, but recent government legislation means that ALL unleaded petrol must have less than 1% Benzine. I don't think all the other nasties get a mention though.
So, again, it all comes back to my main question. Why is 95 still made?
