Now we all know what he's asking.
If your engine isn't high compression or big boost I would run regular 93 and get a good tune. It seems like a waste of money otherwise.

You need to worry about the sensors and the cats. The lead bungs up the sensor and skews the readings. If you run leaded fuel on a cam only engine or stock ( I have no idea why you would, unless you are running Nitrous or Boost) your spending money on fuel you don't need. 93 octane fuel is more than enough for what your are doing, and it will save you money.
