Looks primarily like a solvent. Naptha + Mineral sprits.

Since I'm fairly convinced the bottom oil ring design is responsible for units that burn oil, it's equally plausible that this solvent "frees" up sticky oil-scraper rings to perform their job [correctly] again.

Risky? IDK.

I'm not sure I'd use it continuously...like the website implies.

Sounds more like "Engine Flush" which is used to clean just prior to an oil change.
