Walk down the aisles of almost any automotive store and you'll see a lot of products that can help your car in a number of different ways. But like anything you buy, not every claim a product makes on the packaging comes true. During times of rising gas prices, which seems to be all the time, vehicle owners are on the lookout for a well-priced product that can save them a few dollars in the long run.
There are lots of products in the automotive market that claim to increase or restore the gas mileage in your vehicle. There are fuel additives, air bleed devices, liquid injection and even magnets all claiming to get more out every gallon of gas. Some of them claim to clean out your engine and as a result restore your engine's fuel economy. Others claim to change the molecular structure of the gasoline, heat or cool the gas, or just add air to it to make it last longer. But do any of them actually work?
We've put together a list of five types of products that claim to improve your gas mileage and paired them up against testing done by the Environmental Protection Agency (EPA), Popular Mechanics and other news agencies to see how they did. The government does not endorse, nor does it officially approve, any product so be wary of any gas saving products with similar claims. The Federal Trade Commission (FTC) specifically warns against products that claim to have government backing.
Some may minimally increase your vehicle's mileage, but it may be so small that you won't even notice the difference, especially in your wallet. Other products can actually be harmful to your engine as well. So before you buy that next gas saving system or additive, check out the rest of this article.
