That is not the case with octane ratings. People think that higher octane gas is in some way superior to the lower rated ones. They are all exactly the same quality. The octane number just means it has higher knock resistance. It does not burn "better", "cleaner", more "efficiently" or any other of the misconceptions out there.
There is zero advantage to running high octane fuel in a car that does not require it. Inversely it is a really bad idea to run low octane in a car that does require it!
