Why use premium gas when regular will do? at usatoday.

Many people still think that higher octane is better for a variety of reasons including:
- Its higher quality gas and will give better performance or mileage.
- It has more additives to keep your engine cleaner.

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. It could even be damaging to your car.
The U.S. Environmental Protection Agency requires that all octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against the build-up of harmful levels of engine deposits during the expected life of your car.

See the Octane for more information.
