The gas combusts differently if it's premium. So your everyday econocar doesn't require the expensive gas. Or propane. Says it right in the manual, Mirage takes regular unleaded. I think there is even a warning graphic about wrong fuels. I think the car is meant for some ethanol regular unleaded. The whole owner's manual is hard to understand.
High performance engines are meant to fire their pistons differently than your Mirage.
In short if you're driving a car with a gas or a tire pressure beyond the recommended requirements, you might run into unintended consequences. Tipsy Mirage, funky engine running. etc
