I'm certainly tempted to take you up on your offer maye missus said she might be up for it too [emoji1] [emoji106] But I have used 95 in mine before feels awful when driving and seem to use more fuel. I guess it's using more to compensate. I had no real issue but throttle response from a standing start was noticeably worse. I always use shell when possible but will use tesco momentum or any other higher octane fuel when available. [emoji3]
