The Truth About Octane
Gasolines are generally rated with an anti-knock index (AKI) number that measures octane quality. Determined by engine tests in octane, this number reflects a gasoline's ability to resist engine knock. Engine knock is a heavy rapping noise that can lead to loss of power or mechanical damage. A fuel's octane number does not mean higher quality, performance or improved miles per gallon. It is only the level to which the gas combats knocking. Most cars today are designed for regular unleaded gasoline with an octane number of 87. For a severe knocking problem, for example, an 89 octane fuel will prevent knocking more effectively than an 87. If your car runs knock-free on a lower octane fuel, it is a waste of money to buy high octane fuel. Consult the owner's manual for your car's recommended octane level.
