It's a low grade heavy base stock with a tackifier similar to what's in bar and chain oil. It makes oil thicker and dilutes the additive package. That's it. If thicker oil is needed, just use thicker oil that is almost certainly made from a higher grade base stock and has a full strength blended additive package.
It's expensive, so it's a total ripoff. The definition of snake oil. High quality, fully formulated motor oil usually costs less and is much more effective.
