Too Big Doesn't Hurt

a: Octane rating ~
b: shoe size

What: "I just want to add that In some High mileage engines, excessive carbon builds up in the combustion chamber making it slightly smaller, thereby raising the compression ratio. This can slightly increase octane requirements. Basically, Octane rating is like a shoe size. Buy the right size. A bigger one wont hurt you, but it wont help you in any way."
