From my 2005 Saab 9-3 Aero Convertible owner's manual page 155:
Fuel
Use of the recommended fuel is an important part of the proper maintenance of your vehicle.
For optimum performance Saab recommends:
• 2.0t 175 hp – AON (Average Octane Number) 90.
• 2.0T 210 hp – AON (Average Octane Number) 90.
Gasoline Octane
Use regular unleaded gasoline with a posted octane of 87 or higher. If the octane is less than 87, you may get a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine. A little pinging noise when you accelerate or drive uphill is considered normal. This does not indicate a problem exists or that a higher octane fuel is necessary. If you are using 87 octane or higher-octane fuel and hear heavy knocking, your engine needs service.
