I am a new 2005 TSX owner and new to this forum, so I apologize in advance if my question has already been dealt with.
The manual says to use 91 octane fuel and the inside of the fuel door says that 91 octane is required. However, the Acura Web site says that lower octane fuel can be used with resulting lower power and possible knock.
Has anyone used regular unleaded in their TSX? If so, how much knock did you experience?
