Ever wonder what the numbers 87, 89, and 91 at the gas pump really mean?
This episode breaks down octane rating — what it is, how it’s measured, and why paying more for premium fuel doesn’t always mean more power.
Learn what causes engine knock, how n-heptane and iso-octane define the octane scale, and what that mysterious (R+M)/2 formula actually tells you.
By the end, you’ll know when to choose regular or premium — and how understanding octane can save your engine’s health and your wallet.
