ELI5: The different types of gasoline(unleaded, premium, super premium) 

I understand they have different octane levels but what difference should a driver experience in terms of performance when driving a "regular car" like a Honda Civic or a Toyota Corolla?

The others don't seem to be very ELI5 worthy.  Let me try.

When you squeeze something very hard it gets hot.

When you heat up gasoline it explodes.  Your car uses a spark to make it explode, but it also squeezes it a lot to help.  If you squeeze it too hard it explodes before the spark happens.  (In fact truck engines just squeeze it really really hard and don't have any spark!)

When your car is going the pistons are going up and down and squeezing the gasoline and then the spark happens when the piston is in the right place and it explodes and pushes the piston down again.  If the gasoline explodes too soon, then the piston is still trying to move upwards and the explosion pushes it down the wrong way.  This hurts the engine and doesn't make the car move very well!

They make different types of gasoline to make sure it only explodes at the right time.  If you use a type that needs to be squeezed harder, it might not make as much power if you don't squeeze it that much.  But if you use a type that explodes too soon it might actually hurt your engine.

Too much means it hurts the car.  Too little isn't as powerful.  So you always use the type that is made juuuuust right for your car.
