This will sound strange, but the premium for premium gasoline is actually
shrinking. Think about it. When gas was $2.25 for regular, mid grade was
$2.35, and premium was $2.45. That's a $0.20 difference (which comes out
to being about an 8.88% price premium for premium gas). Now that regular
is $3.00, midgrade is $3.10, and premium is $3.20 - well the gross premium
for premium is the same per gallon ($0.20) - but the percentage is 6.66%.
So, if octane boosters were too expensive to boost octane when gas was
cheaper, they are definately too expensive to boost the octane now.
