Folks, the best advice I can give you is to run away from any “product" that claims to miraculously increase your gas mileage. Over the years, the U. S EPA has tested many of these products and found one thing in common; they flat-out don't work.
In fact, a company that made a product called a “Fuelmax" or “Super Fuelmax" was sued by the FTC for making deceptive advertising claims in October, 2004. The company settled at a cost of $4.2 million. The claims? Magnetic currents would magically “break up molecular fuel clusters" and contribute to more efficient engine operation. While this device is off the market, there are plenty of others out there, with similar claims that are just as worthless.
Modern cars are remarkably fuel efficient - 99.99% of all gasoline is burned and engine efficiencies can reach 35%. Contrary to claims that “clusters of fuel molecules" are not being burned is just plain not true. Currently, there are absolutely no products that you can attach to your car that will give you any better fuel economy. In fact, many will make things worse, and some will violate any warranty your car may have. Is there anything you can do to save some money at the gas pump? Here are a few things you can do to get more miles per gallon from your car.
- Change your driving habits. Cut out the jackrabbit starts, stop racing to the next stoplight and drop a few mph from your speed. Studies have shown that you could see up to a 37% increase in gas mileage. And, that ain't peanuts, and it won't cost you a dime.
- Take care of your car. Change the oil on a regular basis. Using a synthetic oil can make your engine last longer and run more efficiently due to lower internal friction. Make sure your tires are inflated to the max. Look at the maximum psi rating on the tire itself - I normally keep my tires at 33 - 36 psi. Get a tune-up. Modern cars really don't need tune-ups as they did a few years ago, but if your car has more than 100,000 miles, at least consider changing the spark plugs.
- Drive less. Plan your trips - consolidate errands into one big trip rather than a lot of little trips. You'll save gas and time. Shop on the way home from work or school. No miracles here - just common sense.
