They indicate the amount of pressure the fuel can hold up to without causing problems in an engine.Most engines will compress fuel before burning it. The cylinders press the fuel until it is the right density, then a spark plug ignites to fuel to create the energy to run the vehicle.A gas octane rating of 85 can handle less pressure than 89 octane, which handles less than 91, etc.Some high performance vehicles have engines that compress the fuel further than a standard engine.
