John, I think DC summed it up best in his first post on this thread  All I would add is that, if you're down to a quarter tank of fuel, I personally would just use it up then add 98 RON fuel from BP, Shell or Esso only. Knowing you like I do, it may always remain at the back of your mind if you don't  Like DC said, I would never fill up with any supermarket fuel or any 95RON. In continental Europe, I always stick to BP, Shell, Total or Aral. Satnavs are great for locating the right brand on your way
