With gasoline prices stuck well above two dollars a gallon, you might be looking for something to stretch your gas mileage.
But there's a warning for consumers to be on the lookout for gadgets that promise to do that.
For $199, one gadget called the platinum fuel saver promises to increase your mileage by 22%.
You may have seen an ad for it in local newspapers. It's supposed to increase mileage by adding platinum to the air and fuel mixture going into the engine.
Janet Jenkins of Wisconsin Consumer Protection says the federal government's testing shows a different result.
The EPA actually did evaluate this particular device and found no significant fuel savings whatsoever," says Jenkins. "In fact the EPA has said over the course of years it has evaluated 100 or more of these devices and has not found one of them to have significant fuel savings.
n fact, Jenkins says some so called gas saving products may damage your car's engine or increase exhaust emission.
