As gas prices spike skyward, the number of ads that pop up for new performance enhancing gas additives and mechanisms rises as well. Beware the advertisers claims on what these products can or cannot accomplish.

"This product improves fuel economy by 20 percent..."

Typical savings estimates range from 10-30 percent but the US EPA has tested more than 100 devices and products and concluded that although some do increase fuel conomy moderately that none, "do so significantly."

The EPA went on to report that some of the products tested could lead to engine damage and to higher emmissions.

"I got 5 miles better per gallon after I installed this product..."

Sorry folks, this one is pure BS. Glowing testimonials aside, few if any individuals have the ability or equipment necessary to test for precise changes in fuel economy that could be attributed the new product. Mileage is affected by too many variables to determine the exact cause for increase without a very sophisticated testing structure. Traffic, road condition, weather, tire pressure, passengers, etc... can all add or subtract a few miles per gallon.

"This product is approved and endorsed by the Federal government..."

More smoke and BS. From the FTC's website...

"No government agency endorses gas-saving products for cars. The most that can be claimed in advertising is that the EPA has reached certain conclusions about possible gas savings by testing the product or evaluating the manufacturer's data..."

If for some reason the seller insists that it has been endorsed or evaluated ask to see the test results. More than likely, they will not be able to produce.

If You Get Taken

If for some reason you do buy one of these products, you may well want to complain when it does not work properly. Aside from talking to the manufacturer or vendor, you can contact the Federal Trade Commission at their website or at 1-877-FTC-HELP.
