As what Kazukimy said, Racing or not it's only 97. The initial introduction of the Vpower Racing came in as 99, but after a month I think they quietly updated the website saying 97 and didn't say much more than that.Ya meh? last time was discussed before I also thought discon already but someone mentioned still got around R&R's...
I actually have a friend who's a chemist for Shell and he has admitted that it's 97 but the additives they throw into VPR is worth the money so if you're on it, stay with it. It's good stuff.
