This is a big win, for purchases of 95 RON (or higher) fuel, like me. The dropping of higher octane fuel from price boards seemed to coincide with a big jump in the price premium. So more visibility of the price is very desirable.
With increasing numbers of vehicles requiring premium fuel it would be good for the margin taken on it to drop into line with 91RON. Noting that many vehicles require fuel in the name of reduced emissions, rather than increased performance, like the Suzuki swift hybrid. Some markets like the EU have dropped 91RON all together.
Did sadly miss the opportunity to require fuel retailers to list prices online in a scrape-able format. This would be much better for promoting competition (and probiably cheaper to implement) than a roadside price board.
