Fuel types
Unleaded gasoline (93 AKI [Research Octane Number 98] or higher)
If unleaded gasoline with an octane rating of 93 AKI (98 RON) is not avail-
able, unleaded gasoline with an octane rating of 91 AKI (95 RON) may be
used with no detriment to engine durability or driveability.

I don't have a copy of the FRS manual ATM.
Edit: Looks like premium is required, I couldn't find the FRS manual but I did find one of the press releases saying premium was required. Sorry guys, I thought after reading the entry on fuel 6 times I wouldn't get confused on which grade was required.
