The official octane requirement for a 1997 Cadillac Catera is 87 octane, which is considered regular unleaded fuel. However, using premium gasoline (91 octane or higher) may provide better performance and fuel efficiency due to the vehicle's design. Always refer to the owner’s manual for specific recommendations regarding fuel types.
