if 93 makes your car run better than somthing is wrong with it, engine temp too hot, timing advanced ect.. the higher the octane the harder it is for the fuel to burn. the only time you need higher octane is if the heat of the combustion chamber alone is hot enough to light the fuel so it burns before the spark happens and then it causes knocking and pinging and rare occasions backfiring. so if you need higher octane fuel then your car is getting too hot
