does it really matter

johnnyboy · July 3rd, 2006, 02:31 PM

i was told to use regular gas (bp 87 octane) on my 03 gt. I will make a difference in performace and stop that little jerking it does at 25-30. Have you guys had to switch to a lower octane? I thought i was doing good by giving my car premium. will it make my exhaust sound any different?thanks for the feed back.

is your car stock? it wont make a difference in the sound of your car and if you dont have forced induction or advanced timing then run 87 or 89, i know that ethanol shit takes away from the quality a little bit

yeah you put in 87 unless you bump up the timing, got forced induction or what ever. no need to put in premium. just a waste of money.
