Glenore:Octane only allows an engine to run as designed up to the designed parameters.
If you car needs and uses 92 octane, 100 or higher octane will do absolutely nothing more than what 92 octane can brings.
An analogy:
You gas tank can contain 20 gals. pumping in 22 gals. will result in a spill and will be wasted.
You can't put in more gas than the tank designed capacity as you can't use more octane than the engine has been designed to use.
