GOOD question! Modern fuel injected engines with anti-knock sensors and so forth really get no added benefits of any kind by using fuel with a higher octane rating than the engine was designed to use. It's a total waste of money, as the fuel contains the same amount of energy, no matter what the octane rating is. The octane rating is roughly a measure of the fuel's ability to resist 'predetonation', which produces the knocking noise you may have heard from time to time, especiall on older,non-fuel injected engines. Predetonation reduces the efficiency of your engine. Octane ratings have absolutely NOTHING to do with how clean the gas burns, how efficient your engine runs, or how much power you produce. The only time high octane gas is needed is for engines which are designed to use them in order to get their full, rated horsepower output. The high compression engines, in other words. The absolute BEST explanation I have ever found is at this link: http://www.servassistonline.com/Consumers/high_octane.php WELL worth the reading. Especially with todays gas prices.
