don't put regular in your car unless u have some kind of piggy back or stand alone ecu which will redo the timing. |
All higher octane gas lets you do is advance the timing which can increase the torque generated by starting the combustion process earlier on the compression stroke without detonation.
Essentially, there's no additional energy available in the air/fuel mixture, it's simply how it's being used that results in the generation of more power.
