google tufoil and you can see a lot of negative feedback

ceratec used before, ceramic particle based, won't "melt" together. if it stops "sticking" to your engine parts it'll just follow engine oil out upon draining/OCI.
generally, i'd probably trust a big german lubricant company more than an american engine oil treatment company

I've used Ceratec on my Persona, it could have been not bad.
Then I've used Tufoil, and found that it's really effective in reducing tappet noise and giving smooth sleek feel to the rev. I've used 2-3 OCI on my Persona, on N/A and turbo. The engine looks good when they lift the head.
With caution, I've used half the recommended dosage on my Preve. So far no tappet noise yet despite WOT several times.
I'm sure some notices my car is quieter than ordinary Campro cars (before exhaust mod). That's because of Tufoil.
