Searching for the better gas mileage solution

With fuel prices soaring, sales of products designed to boost gas mileage are also rising – even though the government says they're not worth the money.

The products range from devices that fit inside an engine's air intake valve to fuel additives. Their makers claim they boost mileage by helping gasoline burn more efficiently.

“The EPA (Environmental Protection Agency) has tested hundreds of these products,” said Laura DeMartino, a Federal Trade Commission attorney. “Even for the few that worked, the gas savings was so small it didn't justify the price.”

But that's not discouraging people from searching for ways to eke extra mileage out of their vehicles when gas prices are hovering above $4 a gallon nationally.

“Our sales have probably close to doubled,” over the past year, said Dan Baxley, founding partner of Automotive Research Laboratory LLC, which makes the Vortec Cyclone, a device designed to boost gas mileage by improving an engine's air flow.

The $40 device fits inside a car's air intake hose, where it, “creates a swirling mass like a tornado,” Baxley said. That creates a finer gas-air mix than normal, which burns more efficiently. Some Vortec Cyclone users have claimed a benefit of as much as 6 miles per gallon, though most see an improvement of 1 to 2 mpg, he said.

Kevin Shaw, vice president of development at The Coffee Beanery, has tested it on four company vehicles.

The coffee chain found that it improved the performance of two of his service vans by 2 miles per gallon, while one passenger car's fuel efficiency rose by 1 mile per gallon. The fourth car saw no improvement, but Shaw said three out of four is enough to convince him that the device is well worth the money.

Like other companies that sell gas-mileage-improvement products, Baxley is used to skepticism.

He says his company's tests prove that the Vortec Cyclone improves gas mileage, and Automotive Research Laboratory backs its product up with a money-back guarantee. Returns run only around 5 percent of sales, he said.

National Fuelsaver Corp., which makes Platinum Gas Saver, can improve fuel mileage by 22 percent, said company owner and technical director Joel Robinson.

The product, which the company started selling nearly 30 years ago, injects a small amount of platinum into a vehicle's air intake system. The platinum molecules boost the amount of fuel burned by the engine, company press materials say. The remainder is expelled as vapor and burned off by the catalytic converter.

Robinson said he's been able to defend his product thanks to his victory in an early 1980s lawsuit brought by the U.S. Post Office, which said he was trying to obtain money through the mail by making false claims.

Robinson produced data that, he says, show Platinum Gas Saver works. But he also notes that – aside from his product – there is merit to the FTC's warnings. “The problem in selling this product is that in the last 10 years there have been 10,000 phony fuel savers,” he said.

The government's advice to people looking to save on gas: Drive the speed limit, use cruise control, combine errands and remove excess weight from the trunk.
