Is anyone still interested in knowing where to purchase them, Or know if the item works on the pistons like it says?

Pellets perhaps? Don't waste your money.

It has been a very good product for me 15 years ago when my mechanic used it on my 1980 mustang and also 2 months ago with my 1990 Honda, the smoke stopped, settled the sound of the motor, I am glad I have had good results. Do you have apersonal story with it?

These gimmicks are just that. They may temporarily "fix" something but it will not last. F any of these things actually worked long term, there would be a lot of mechanics out of work
