TeraClean? Any ideas?

[Mark R]

Has anyone here had their car teracleaned? It's advertised as a carbon cleaning system which removes carbon from valves, injectors, lambda sensors, and catalysts.

I'm always a bit sceptical of this sort of miracle engine clean type product/service. But, I recently had an unsolicited testimonial from a mechanic at an emissions inspection center, who says that he's seen a few cars fail emissions, then come back later in the day after being teracleaned, and pass so well, he hadn't ever thought that such improvement would be possible with cat replacement/major engine work. He doesn't offer the service himself, and I doubt he's getting kickbacks; in fact, he was more asking me if I'd heard about it being a "scientist type".

Their web site is full of "blind you with science" type stuff. So, when I googled "coulombic fractionation" which they promote as their major technology, it was a bit suspicious when google came back with nada.

Apparently, they disconnect the car's fuel pump, and connect it to a machine that dispenses their "cleaning fuel" directly into the fuel injection system. The engine then runs on their "molecular fuel" until the fuel is depleted, at which point the cleaning is complete.

So, any comments?

I think your post describes BS.

Fuel from reputable outlets already has additives to keep things clean and lubed and in good shape.

You shouldn't clean your fuel system or injectors unless there is an indication that it needs to be done, imo.

Seems like a really expensive seafoam treatment (snake oil?) without some of the benefits.

Edit: "coulombic fractionation" being the transport of material by use of electrical current? Maybe it removes carbon by electro-chemically stripping the engine's base metal...? Seems... sketchy.
