I see at least as many people filling up with PULP as I do ULP these days.
There certainly do seem to be more people using it. I used to go to our local Coles Express quite regularly, as they were often the cheapest in the area for PULP (not any more, they're usually as bad as - or worse than - BP's prices) but it gave me the irrits that less than half the pumps had PULP, especially when the place was busy. You did NOT make yourself popular when the two cars ahead of you at the pumps pulled away and you had to stop at the first pump (which was always the one that had PULP), thereby blocking access to the one in front. At least most other retailers have all fuel types at most (if not all) pumps.
