Premium gasoline is not regular gasoline with "octane boosters" added.
It's different stuff. Well, the octane booster is usually, wait for it,
isooctane. But it's not some magic stuff. It costs more, because the
yield per unit of crude is lower. (Premium gasoline usually has other
things added to it, other than just iso-octane. Detergents and deposit
control stuff are usually present in higher levels than regular
gasoline, but they're not required to.)
