Those were the days ah Jeff. Fish and Chips in the news of the world, chalk and slate boards and 3 gallons of premium (14+litres) for less than a quid. Mustn't forget the green shield stamps. I honestly don't believe that during normal driving the extra Ron is really noticeable. Having said that I do alternate fill ups using both 95 and 98. At least this satisfies the BMW 98 Ron preferred but 95 to 98 recommended.
