Our love affair with the car is no longer a cheap date considering today's high gas prices. But are there secrets out there that would allow you to get more miles for your money?
Plenty of companies claim if you just buy their products, you'll save on gas.
The infomercial for the Tornado Fuel Saver says "its fast and easy installation can save you up to $20, $40, even $60 a month at the gas pump."
The company's president, Jay Kim, has appeared in his own infomercials to plug the Tornado. Kim says scientific tests, including some done by ABC affiliates, prove that his product works, but other experts say those road tests don't mean anything. According to Kim, he's sold 100,000 of these products.
"People put the Tornado in, they are so happy with the product, they tell a friend," Kim says. "So I'm very confident that [the] product works."
But Consumer Reports disagrees. It tested the tornado in 2005 at its test track in Connecticut, and found the Tornado didn't save gas. CLICK HERE for a recent summary of Consumer Reports' tests.
"During those tests, we splice a fuel meter into the line, run them through very strict tests, so we really get to know whether these things work or they don't," says David Champion, director of automobile testing.
"We tested it on two cars, [it] made no difference at all."
But Kim still stands by his product.
"I think that someone made a mistake," Kim says.
The tests that Kim is referring to, he says, are like "actual real-life, real-on-the-road testing" that came from the ECOlogic Engine Testing Laboratories.
But we spoke with ECOlogic, and the man who signed off on the test, Donel Olson, says he's sorry that it has his signature on it.
Kim maintains, "Tornado works. That is the bottom line."
Another product, the Platinum Gas Saver, guarantees a 22 percent savings on gas.
It's yet another product that Champion has doubts about.
"We tested it on two cars, made no difference at all," he says.
Joel Robinson invented the Platinum Gas Saver, which he sells for about $200.
We told him that Consumer Reports tested his Platinum Gas Saver on two vehicles.
Robinson's reaction: "Well, two means nothing. We can show you in our own test data. … I can show you two vehicles. One that got 12 percent worse and one that only improved by 7 percent. But if you take all 42 vehicles, what you see is an improvement of between 20 and 28 percent."
Using data from that test done more than 20 years ago, Robinson kept the government from shutting his business down. The Environmental Protection Agency later ran tests and now says the product doesn't work.
Robinson questioned just how valid the EPA's test is.
"The EPA test is done in a laboratory," Robinson says. "The vehicle sits there on the floor, and the rear wheels are rotating on cylinders.
"There's no road vibration given to our dispenser," he adds. "Therefore, no platinum is going to get dispensed. Therefore, I'm not surprised they wouldn't see any results, even if they did a test."
Robinson defends his product, saying, "Obviously, what we're doing is obviously scientifically and testwise correct."
But if his device works so well, then why after 25 years isn't everybody buying it and saving all this money?
His explanation: "We have three vested interests who don't like us: the oil companies, the car companies, because we double engine life, and the cigarette companies, because I was involved in the first litigation that they lost."
