A technician at a N. Calif GM test facility explained to me that the computer module on the SSEi can adjust engine timing, automatically, for 87 octane fuel. However, when I know I will be driving in mountanous areas, I prefer to switch to 89 or 91 octane fuel, to reduce the possibility of pinging during long or severe uphill climbs, and, the engine feels a bit more responsive, to me. He suggested using a fuel with cleaning additives every 3-4 tanksful, also, to help keep injection system clean. That is more cost effective than pouring additives in your gas tank.

According to the 2008 Bonneville manual it uses 89 octane or better unleaded gasoline.
Premium unleaded. It says this on the gas tank cap.

Hi, unleaded over 92 octane is good but you can run 89. Change oil very often if you have supercharger SSEI
The gas gauge sending unit would be located in the fuel tank.
probably out of gas
regular unleaded - 87 octane
A supercharger, advance the ignition timing, reset the ECU, use high octane gas.
It is inside the gas tank
low on gas maybe
