I would think octane is octane; it is a measure of how combustible fuel is. I wonder if fuel economy is better with higher octane. I have tried using higher octane fuel (premium is 91-93 octane here) but did not notice a difference. Regular fuel here has an octane of 87. I think you can even buy octane boosters by the can to add to regular fuel. At some point you would think there would be potential for engine damage.
Does anyone know the details about this?
