Tried this stuff. Before, the tops of my pistons were pretty black. After a tank they are now shiny. Promising for what else it has cleaned out.

Very impressed !

I have to confess that after reading reviews of the product, I purchased a box of it, and I figure I'll run a bottle thorugh after each oil change. That way, it's easy to remember and a good maintenance procedure.

Yes I did half per tank. The bottle does 20 gallons so assumed half for our 10 gallon tank?
