probably. It has a high performance high compression motor. Those types of engines usually require high octane fuel.

Yes it is.Any 180HP+ 4 cylinder engines require premium.The Civic Si has 197HP.Any turbocharged or supercharged car requires premium.All powerful engines require it.Some cars only recommend it. It says whether it is required or recommended on the gas cap.On the Civic Si, it is required.

Yep that's what it takes and if you try to put another octane below 91 the engine light will come on and you will feel the loss in power.
