The octane rating has nothing to do with performance. As long as you use the octane recommended for your engine your good."The short answer is that octane is the measure of how much compression a fuel can withstand before igniting. Or, in laymans terms, the higher the octane rating, the less likely the fuel is going to pre-ignite (read: explode unexpectedly) at higher pressures and damage your engine."
