There's a lot to know about this, and if it's not an MPS, there's no need to run it on super. The knock sensor and ECU are set up to run 98ron like an mps.

Yip I agree with misar and the salesman. Both of my Mazdas, a 2009 and a 2013, have had problems with fogging up, especially when it is very wet outside. I just got a moisture-absorbing bag at Halfrauds for £10, and it seems to work great. You just put it on the dashboard overnight, and the windows are clear in the morning.
