Do these capsules work? They are supose to decrease emissions, increase fuel efficiency and clean your car’s engine. Is it too good to be true?

Snake oil. Or maybe I should say, snake droppings.

The only thing they will decrease is the amount of money in your wallet by increasing the rate at which it leaves so that your wallet is cleaned out.

At best, they will not do your car any harm.

No, they don’t work. They are completely and totally worthless. Don’t waste your money.

For future reference, ANY product that makes similar claims is equally worthless. if such a “miracle” existed, it would be common knowledge, and not an internet secret.

Just another scame. I don’t remember the details but I think the state of Texas went after these people; or some of their clones.

A hint of what they’re all about.
