Just a quick question on this subject,
when performing an adaption run, should you use, 95 or 98 ron?
for myself, i done an adaption run using 95 ron, as thats what i use all the time..

yeah - you should adapt using the fuel you plan to use.
If you adapted using 98Ron, it would run a slighly higher boost - but it would drop back as soon as you put 95Ron back in.
Not sure which car you have, but the 9k Aero is 'designed' to run on 98Ron - and runs much better on it too.

Hi faero,
my car is a 96 MY 9000 aero,
i though that it was the earlier aeros that were designed for 98 ron and the later 95?
maybe im wrong?

If you open the fuel flap you'll see it states 98Ron (my 96 Aero does anyway).
Oh - just realised that if its an auto it will have the 200bhp running a bit less boost and probably doesnt specify 98ron.
There is nothing wrong with running 95Ron. In theory through, the spec of the 225bhp engine is achieved using 98Ron.
In the end, the higher the boost, the more the higher Ron fuel will become useful in preventing pre-ignition.
