Agreed with this. These products always seem to work well until later when you find out they are just a bandaid.
I would be concerned that the product would cause rubber gaskets to swell. That is usually what these products do so that used car dealers can offload a problem car before you know what is wrong with it. Unfortunatley this also promotes cracking in the rubber. Also, I think that its copper (I don't remember) that sticks to the rings to help restore some of the compression.
BTWay. just how is this product getting past the oil scraper ring to the compression rings??? Must be burning oil--time for a rebuild, or bandaid the engine and offload it.
IMHO, I think that the multitude of dollars spent on oil additive research at the refinery/factory are enough. The additive packages are produced to maxamize the benefit to your components--not for a quick sell. If you want better quality then get synthetics. Synthetics start out with a better base blend of additives than the dino based oils.
