SmogBuster tested by scientists, turns out to be useless, film at 11

Wouldn’t it be great if you could stick something the size of a quarter on the gas tank of your car and suddenly get better fuel efficiency?

The OCN SmogBuster™ Disc is a custom holographic disc that is able to store and project proprietary programming that affects the properties of the gasoline or diesel fuel, causing it to burn cleaner and more efficiently.

The press release has more details:

The disc is about the size of a quarter and easily installs on the gas tank. The proprietary technology has consistently reduced smelly, smoky exhaust and in addition increases gas mileage and engine performance. Many who have tried the product report a change in emissions in a matter of minutes and a burn off of carbon deposits, increased gas mileage after a few tanks of gas.

How much would you pay for one of these marvels? Five bucks? Ten? Think again—the SmogBuster is $299. However, you can get it for a mere $199 if you join their innovative pyramid multi-level marketing scheme.

Of course, there are always critics:

“It doesn’t work,” says Dr. Terry Parker, a physics professor at the Colorado School of Mines. Parker and graduate student John Dane of the chemistry department tested the device for 9News.

“It’s clear that it’s just a sticker and nothing else,” Dane said.
