Hi I've had my 200thp for about a year now and I'm running it on normal 95 octain fuel. A friend told me that it's not worth running 98/99 unless you have a jap import as European cars are designed to run on 95 octain. I was told yesterday that some modern cars have 2 maps on the ecu and can detect which fuel you have in it and run accordingly. Does anyone have any info on this? I know some of you must think it's sacrilege but if theirs no point theirs no point.
