Even though airplane fuel is not 100octane buy auto standards is it better than 93 pump gas in our cars?

No. Avation fuel is actually low leaded. Dont run it unles you plan on screwing up your catalatic convertors and your O2 sensor. A dude I know runs it (in a carburated big block) and it spews a faint blue smoke too.
