Actually there is more energy in the 98RON fuels currently being marketed by Shell,BP, Mobil and Caltex. I did a survey some months ago and found that their density is somewhat greater than regular ULP hence greater energy per unit volume. Some of the above company's have the density stated on their web sites and other I sent an email and got a response.

So there is a technical reason why there should be a greater fuel economy when using these fuels but older engines will probably need to have their timing advanced to take full advantage of the higher RON. Most EFI engines only have passive knock sensors and will retard timing should they detect any knock, some higher performance vehicles do have active knock sensing and will advance timing to take advantage to better fuels.
