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?
