Have you noticed ads for pills or powder or even liquids that you put into your gas tank and, magically, you will get up to 30% better gas mileage? Wow, that's more powerful magic than Harry Potter can produce! The number one selling fuel pill out there was a product made by Bioperformance. Their product was known as the gas pill or the fuel pill.

The product came under the scrutiny of the State of Texas Attorney General, as Texas was where Bioperformance was located. After investigating, the attorney General filed criminal charges against Bioperformance and it's owners. The Attorney General stated "We will aggressively fight these con artists who cynically exploit the public's concerns about high gas prices to line their own pockets."

He referred to them con artists. That is exactly what they are. It seems, if you had put moth balls into your gas tank you would accomplish the same thing as the fuel pill. The fuel pill was found to be basically the chemical equivalent of mothballs.

Bioperformance and it's owners were really only out to recruit as many investors or paying members as they could into what at this point looks like a full blown pyramid scheme. That was according to statements made by the attorney general.

Believe it or not, there are still companies and products out there that are making the same claims all over again. MPG-Cap is one. Another one is Enviro-Max. They promise essentially the same thing Bioperformance did. They claim you will get big increases in gasoline economy simply by dropping their pills into your fuel tank.

Basically their claims are based on testimonials from drivers. A driver cannot scientifically make valid comparisons in mileage. There are too many variables. To really do a valid test, the test needs to be done under controlled conditions with sophisticated and expensive monitoring equipment.

Normal driving conditions of weather, traffic volume, accidents and stop light patterns have a tremendous impact on any days fuel economy. There is no way the average driver can take those factors into consideration to be able to run a sound test.

Enviromax Plus claims that it makes gasoline burn more efficiently. It claims it will lower the unburned gas in your engine from 15 percent down to 1 to 2 percent. Unfortunately for Enviromax but fortunately for you, todays current engines actually burn gas with an efficiency of about 98 to 99 percent. That is without any help from EnviroMax.

The bottom line, save your money. Don't believe the wild claims of these modern day snake oil salesmen. As always if it seems to good to be true, it is!
