soo, anyone live in toronto actually felt the difference between 91 premium from shell or esso, and 94 high performance from sunoco?
also, since cops are more strict now about street racing , and how much attention i attract with my 3.5" muffler, anyone no any places in the scarborough / markham / richmond hill area that carrys a variety of silencers?
thanks for the help!

 

Higher octane means a higher activation energy which results is a greater resistance to detonation. You won't feel the difference.
But, if you have a turbo car, the 94 Octane gives you a greater safety margin against zoom zoom boom!
