I have just purchased a 320si limited Edition, I was reading the manual and noticed the recommended fuel grade should be 97ron , I ran the tank till nearly empty and filled up with £20 worth of 97ron fuel since doing so the car runs like a Kangaroo on speed , surely this should improve the running of the car ?
Any thoughts on this would be appreciated
Thanks in Advance
