a: Octane rating ~
b: choosing a ladder to get over a particular wall
What: "Best way to look at fuel octane rating is like choosing a ladder to get over a particular wall. Too short a lader and you are stuffed. About right and you will manage OK, with a slightly higher ladder being a bit safer (ie, octane rating of a fuel degrades with age, hence one reason old petrol can cause issues). Go beyond that and you are not gaining anything except the expense of a longer ladder and making it more difficult for you."
