Probably nothing wrong, some 9's use more oil than others, at the recent trackday mine hardly used a drop, where Han had to top up all day. I had previously used Silkolene pro-s 5w 40 on my tuned 172, and it is one of the highly recomended oils from Opie for my 9 also, these guys know there stuff, quality costs.
