High gas prices this summer may be bad news for consumers, but they spell opportunity for quick-buck marketers eager to sell you something -- anything! -- regardless of whether it's beneficial.
Take gas-saving devices and additives, for example.
The U.S. Environmental Protection Agency tested over 100 supposed gas-saving devices, such as mixture enhancers and fuel line magnets. The results indicate that very few products provide any benefit and that some can cause engine damage or increased emissions.
There are, on the other hand, some tried-and-true methods for saving fuel:
Use only the octane level you need. The level specific to your car is indicated in the owners manual and all gas pumps are required to have their octane rating posted. Using a higher octane that the manual specifies does nothing to improve performance; all it does is burn money.
Maintain your vehicle properly. Keep the engine tuned, tires properly inflated and aligned, change the oil and replace the air filter regularly.
