How to Protect Yourself: "Gas Saving" Products
Source: The Florida Attorney General's Office

Wouldn't it be great if you could buy an inexpensive device for your car that would significantly improve fuel mileage and save you money? Unfortunately, most gas saving products don't work at all, and none have been found to significantly increase gas mileage.

Advertising claims.
When gas prices increase, you are more likely to see the "too good to be true" claims of gas saving device sellers. You should be skeptical of the following claims:

Substantial fuel savings.
More than 100 alleged gas saving products have been tested by the Federal Environmental Protection Agency. Only a few of these have been found to improve gas mileage, and none have done so significantly.

Glowing testimonials from the company's "satisfied" customers.
Testimonials may be fabricated. But even if they are authentic, they may be misleading. Consumers who feel they are getting better gas mileage do not have the ability or the equipment to conduct accurate testing. Moreover, there are too many variables that affect fuel consumption, such as traffic, road and weather conditions, and the vehicle's condition. In one case, a consumer sent a letter praising a company's gas-saving product, but that consumer had just received a complete engine tune-up which was the most likely reason for fuel consumption improvement.

Approval by a government agency.
These kinds of claims are simply false as no government agency endorses gas-saving products for cars.

Adverse affects of "gas-saving" devices.
Aside from wasting your money, installing these products on your car could cause your manufacturer warranty to be voided, because they are not factory equipment. In addition, long-term use of such products may actually damage your vehicle.

Real money saving tips.
At the gas pump, buy only the octane level you need. Check your vehicle Owner's Manual to determine what the manufacturer recommends. If your engine "pings" or "knocks," you might need a tune-up or a higher octane fuel.

Get tune-ups.
Get a tune-up at the intervals recommended in your vehicle Owner's Manual.

Check your tires.
Check your tire pressure regularly. Underinflated tires will cause your car to use more gas.

Remove excess weight from your car's trunk.
