Should I use hi octane premium petrol, and what is octane rating?

Will high-octane fuel make your car go better? Will premium petrol make your car run more economically? More smoothly? Cleaner? Or any combination of those things? No. Premium petrol claims are almost entirely bullshit, and the bits that aren’t bullshit are almost entirely over-blown marketing hyperbole. If you need high-octane gas, you need it. If you don’t, it’s just a waste of money.
