Japan Specs (Fuel Recommendation)
I found this online. I guess the "Japan Spec" Auris 180/Scion iM/Corolla iM (2ZR-FAE, 6spd manual) is tuned to run on 95 RON (91 AKI). The CVT model is tuned to run on regular 91 RON (87 AKI). Again, this is not to start an argument, just sharing this link that I found.
I believe those specs listed are Toyotas in Japan.
