Few Devices Actually Save Money on Gas
July 01, 2008
As gas prices continue to be on the rise, so too is the volume of advertising for "gas-saving" products, designed to appeal to consumers looking for ways to improve fuel efficiency.
Although there are practical steps car owners can take to increase gas mileage, the BBB warns consumers to be wary of gas-saving claims for automotive devices or oil and gas additives.
While some of the gas-saving products have been proven to work, the savings are small, at best. What's more, you could end up with serious engine problems or a voided manufacturer's warranty by adding after-market devices to your engine.
The BBB recommends being particularly skeptical of the following kinds of advertising claims:
* "Product improves fuel economy by 20 percent." The Environmental Protection Agency (EPA) has evaluated or tested more than 100 alleged gas-saving devices and has not found any product that significantly improves gas mileage.
In fact, some "gas-saving" products may damage a car's engine or cause substantial increases in exhaust emissions. Some of these products include air bleed devices, vapor bleed devices, liquid injection, fuel line devices, mixture enhancers, internal engine modifications and more.
* "I got an extra 4 miles per gallon with your product." Although ads may feature glowing customer testimonials, consumers should keep in mind that few people have the ability or the equipment to test for precise changes in gas mileage after installing a gas-saving product.
* "Approved by the Federal Government." No government agency endorses gas-saving products for cars. However, the EPA has reached certain conclusions about possible gas savings by testing or evaluating the product.
Instead of searching for miraculous gas-saving products, the BBB recommends that consumers consider taking no-cost or low-cost actions that can help drivers save on gas consumption.
