The same leap of faith you make when you press 94 octane from a pump that can dispense 89.

I have always wondered, but spoke to a state inspector and they do random test for octane rating. After talking with him I am fairly sure I am getting what I pay for. However per his words there are so many stations and he has to inspect them all. So a recently inspected one has a clear window of one to two years before they can expect a suprise visit.
