see when i first go the car i did but about a year ago i stopped cause i got married and then my wife and i had a baby so i just started putting 87 in and it dawned on me that right after that the car started having some problems. this has been going on for a while.
 
You should feel some knocking I believe in order to switch to another level... But if your car is stock and you don't have it tuned then putting 93 will be just a waste of money...
 
settle in the middle with 89octane,ha.
