RON 95 vs 99

Hi all,

Just a quick question, has anybody noticed any advantage using RON 99 fuel over RON 95, i 'm mainly thinking about better MPG.

Highest I am offered is 93, and have no issues though I am not a gas snob either. there has been some light discussion in the past, but if you have heard of the principle of diminishing returns, it sounds like it would very much apply to the 95 v 99 scenario.

You have to map your ecu with different fuel grades to see any real difference.
