a viagra pill for our gas tank?

does anybody knows about this:

i know a guy that say it really works, but he own a civic, i dont know how is gonna work for us

from what the site says theoretically it should work. its a know fact that not all the gas burns within the combustion phase, and thats where mpg and hp is lost. So the problem is real.

But i dont know if the pill is real. they say its a catalyst that will help all the fuel burn on ignition. No way to say if it works till someone tries it. If its true that it works like they say, then you should see some gain, donno if it will be noticable though.

i would have thought that will all the money going into the fuel industry they would have thought of putting all sorts of chemicals and catalysts in there (which they do), so im a little suprised that the answer is a pill.

Sorry, these products don't work.

They admit ...

that modern fuels already burn at 99.5% efficiency and that their catalyst doesn't extract more energy or efficiency from the fuel.

Yet they claim ...

a 7-14% rise in fuel economy as well as a 30% increase in force at the piston during each downstroke, resulting in more "pep" and acceleration.

Their explanation?

An unknown substance bonds to all combustion chamber surfaces and then attracts a fuel catalyst. As the fuel ignites, the nano-layer catalyst changes the rate of combustion, sending a pressure wave toward the piston head with 30% more force.

The problems ...

1. The fuel filter. Does any of the catalyst and adhesion substrate actually make it to the combustion chamber?

2. Coatings are bad for engines. They clog injectors, foul spark plugs, and reduce tolerances between moving parts.

3. Chemical bonding is bad for engines. It takes a chemical reaction, usually with acidic and basic solutions, to bond substances to a metal surface. Acidic and basic solutions = damage.

4. They admit the coating isn't durable. It either wears off or burns off. Either way, it will take "bonded" metal with it, leaving pits and scars behind.

5. Combustion doesn't start at the walls. It starts at the spark plug and expands outward in a sphere. By the time it reaches the catalyst on the sides, the process is over ... it's too late to affect burn rate or efficiency.

Hmmm ... what do do?

very good points. but from what i understood of this about number 5 is that the coating is to keep the heat from going into the block instead staying in the cylinder where its needed, not that it will burn from teh walls.

just wanted to say what i thought they meant. but i agree that it most likely doesnt work, but i cant knock it till i've tried it, and im not gona try it for those reasons you said up top, so as a result i just cant knock it.

maybe it works more like a placebo for the car/truck, it thinks it can therefore it can.

Only thing it does is lighten the wallet.

If their coating significantly insulates the cylinder wall, I'd be very surprised. But I'd be even more surprised if this company actually knew more about combustion temps and rate-shaping than GM (or any other engine manufacturer).

You know, I rode the oil additive bandwagon a while back. (Yeah I know this one's a fuel additive.) Started with Slick-50 and moved "up" to Pro-long and a couple of others. I ended up with rough starts, noises (the bad kind), hesitation and less power from the damage I did to the engines in those cars. If I'd only spent that time and money on scheduled maintenance, they would have lasted longer and been more reliable in the end.

The more I learn, the more I trust the manufacturer. If an engine's inefficient, the problem is the design, and no additive will fix that.
