It's Group I bright stock with zero additives, red dye and some bar oil tackifier in it. The only thing it "works" at is increasing viscosity because it's >3x thicker than straight SAE 60.I personally like it. Never had bad luck with it. Everyone I know likes it as well. How is it a scam?
It puts the snake in snake oil.
If you are now wondering how that combo could possibly "stabilize" anything you are headed in the right direction. That's why it is a scam.
