Miracle Zinc continued

Zinc is used for extreme pressure, anti-wear engine protection. It is particularly useful in high stress, prolonged metal-to-metal conditions found in racing, for example. But, for all of its fanfare, racing conditions are not what the vast majority of motorists face.


Your automobile should never face such stress under normal, everyday driving conditions. Interestingly enough, years ago oil companies reduced the amount of zinc in standard engine oil packages due to damage to catalytic converters and increased spark plug fouling.

Furthermore, zinc is a hazardous substance. It has the capacity to inflict severe damage on your eyes if in contact with them. As an engine oil additive, it really hasn’t “lived up” to its original high expectations. And as a “miracle”, you can’t start a new religion with this one.
