The Carlube Lead Substitute (QFS300) is an essential additive for owners of classic cars and vintage vehicles originally engineered for leaded petrol. It provides critical protection against valve seat recession and wear while simultaneously maintaining fuel system cleanliness and preventing internal corrosion. While it is highly effective at preserving older engine components, owners must remember to add the formula at every refueling session to ensure consistent protection.
