ECO-Fuel Systems: Is it snake oil?

I saw a story on our local NBC station (they have also run several stories on GreaseCar systems) about a contraption called 'ECO-Fuel' that is supposed to extend your fuel mileage and produce a more complete combustion. Their site says it works for gas and diesel powered engines. A fleet of vehicles here in Las Vegas says they have been using them and have saved lots of money on fuel.

Here's what they says about it:

The Eco-System is installed inline on your vehicle's fuel line after the fuel filter. When the fuel passes through the unit it creates a catalytic reaction, breaking up the hydro carbon chains in the fuel, causing the vapor pressure to increase. This increase in vapor pressure causes the fuel to burn more completely in the combustion chamber. The more complete burn means lower emissions, increased power, less hesitation and less fuel. By the fuel burning more completely, you also have less carbon buildup, cleaner injectors and less carbon going into your oil.
Has anyone seen this before and/or does anyone know if it is real or is it bogus?

Here's the link to the EcoFuel Systems website:

Here's a link to the story about the fleet of vehicles using it:

Sanke-oil.

It's a freaking magnet. Goto your fridge, grab a few and stick them on your fuel line. Same effect- none.

I bet you they saved fuel because the drivers knew they were going to watch fuel consumption when it was installed and they cut back on the BSing they would have normally done. (And/Or) The drivers were given incentives to increase their MPG.

It's been done at my job. The truck drivers were offered $100 per MPG they could raise from last years baseline.

The web site claims that it does not use magnets.

It says it uses... wait a minute, it gives absolutely no clue what it might use to perform its magic.

I agree with FI. It affects the drivers foot on the pedal.

With out testing it to be sure I would be inclined think its snake oil.

They say it uses a catalyst to break up the hydrocarbon chains. This increases the vapor pressure of the fuel. Which in turn causes the fuel to vaporize easily.

Basically they are claiming they are doing a form of "cracking" which is what refineries use to covert heavy oil into gasoline. To do it at low temperatures and in such a small device it is doubtful it works. Besides the longer chains have a higher BTU content.

Usually, a catalytic reaction creates tremendous heat. Somehow, I do not think that is a good idea on a fuel line, especially on a gasser.

If you do a temp reading on a catalytic converter on a gasser, you will find higher temps there than any other part of the exhaust system. Knew a girl who parked her car in tall grass, and left the engine running. About 5-10 min later, that car was a total loss. The grass in contact with the converter ignited accordingto the FD.

Its a very old snake oil that has been going around online for quite some time. These type of things pray on people with limited mechanical knowledge and usualy cost $19.99.

Do they have an independent lab that will certify the results? If it is so good, why hasn't the Big 3 bought these things to increase their CAFE for the smaller cars?

I'm not surprised that it's BS - I'm just surprised that they have the cajones to charge $400 for it. I guess they figure if it is expensive, people will think it is something real.

I wonder what they would 'say' it would do for a WVO setup.... hmmmm....

They work, seen it with my own eyes. Fuel gains are minimal on the gasser 1.5-2mpg is what I've seen reported back with unbias testing.

You've seen what with your own eyes? This is snake oil and I'll donate $100 to your favorite charity for Christmas if you can SCIENTIFICALLY prove otherwise.

I used to feel sorry for intellectually challenged victims of snake oil salesman. Each of the victims should have attained the critical thinking skills to prevent being a victim of most of these frauds. They should have attained those skills in junior high school. As I age, I no longer feel sorry for them. For the most part, they deserve what they get.

I know that sounds a little harsh. To make up for that, I've got a carburetor that has been SCIENTIFICALLY tested and guaranteed to get at least 98.43 mpg on every 4, 5, and 6 cylinder diesel engine currently registered in the USA. I'm selling it for only $499 and you must act fast. This is the only one left over after the oil companies and auto manufacturers bought the patent and made me swear not to sell any more until after we've converted to hydrogen fuel cells. Act now, and for no additional charge, I will include a fully tested red light changer for small cars. No more waiting untill a full sized truck pulls in behind you to trip the circuit. Remember, suspend your intellect and act now. It can't last for long.

Okay, go join some gassr boards and see what people are reporting back. I know about 4-5 people off the top of my head that have received one for free. Gains are there, yet they're minimal.

Would I buy it? No. Does it work, yes somewhat.

This isn't like fuel line magnets or the tornado or throttle body spacers for direct port cars.
