Have you ever wondered what's really different between the three gas types/octanes? Did you ever wonder why you should use one over the other? This article breaks it down for you. But if you want a summary... if your car isn't made to use higher octane gases, putting a higher octane in there just wastes money. If your car IS then it's only really important if you want to get the full amount of power. Though using a lower octane than recommended can lead to "engine knocking" at higher RPMS (which is bad).
