    Pros: Delivers what they say
    Cons: Price is a little high & Doesn't do as much for new cars

    Summary: The FTC got zMax two ways. The first was if you use it in a new car you won't get the percent of increase that they claimed. The second was in the corrosion test, they only tested the product alone. zMax is meant to be added to motor oil so the results ... read more
