Then why does the FTC say this?

"The Low-Down on High Octane Gasoline

September 1997

Are you tempted to buy a high octane gasoline for your car because you want
to improve its performance? If so, take note: the recommended gasoline for
most cars is regular octane. In fact, in most cases, using a higher octane
gasoline than your owner's manual recommends offers absolutely no benefit.
It won't make your car perform better, go faster, get better mileage or run
cleaner. Your best bet: listen to your owner's manual.

The only time you might need to switch to a higher octane level is if your
car engine knocks when you use the recommended fuel. This happens to a small
percentage of cars.

Unless your engine is knocking, buying higher octane gasoline is a waste of
money, too. Premium gas costs 15 to 20 cents per gallon more than regular.
That can add up to $100 or more a year in extra costs. Studies indicate that
altogether, drivers may be spending hundreds of millions of dollars each
year for higher octane gas than they need."
