Full synthetic lasts longer than conventional oil, lubricates better etc. 93 has more octane which gives it a better controlled burn. Lets say you used 87 octane in a high compression car, because of the fuels lower octane the fuel is more unstable in the combustion cycle and can detonate before the piston reaches the top of the cylinder(and you f%!k up your motor), with a higher octane you get a more controlled burn and therefore you can run a higher compression (more power) and you can swing those pistons around alot faster (like those hayubusa's and cbr's, formula 1's and so on) someone with a better vocabulary will be able to explain it better.
