I don't think any of the 98-99RON fuels have ethanol in them - there's been a very informative thread recently on one of the MB forums I frequent, that's what flagged this to me as we have 17 cars heading for France and Belgium on Friday! Over here it seems the 95 RON fuels contain 5% ethanol so would be OK - although I only use 99RON in my 968, I often used regular 95RON unleaded in my 968 coupe without problems. However, I understand that in France there are E10 (10% ethanol) as well as E5 95RON regular unleadeds, so we owners of older cars have to be careful.
