ZDDP Plus Oil Additive

Product Details

VW air cooled engines need the Zinc and Phosphorus that ZDDP provides..

ZDDP Plus is not a typical oil additive. By adding a small 4 ounce bottle of ZddPlus at every oil change, an adequate amount of Zinc and Phosphorus will continue to protect your classic engine. ZddPlus simply maintains the Zinc and Phosphorus that has been removed for US, Canada, Asia, and EU motor oils.

How ZDDP Plus Works
When the pressure and temperature of a metal-to-metal junction increases, the compounds in ZddPlus are already in place creating a barrier that prevents the two metals from coming into physical contact with each other.

How Much ZDDP Plus to Add
We recommend adding the entire 4 ounces of ZddPlus per 4 to 5 quart oil change. Just unscrew the cap and pour the entire contents of the ZddPlus bottle into the engine oil input of your vehicle. This will yield the proper amount of Phosphorus and Zinc. (Large capacity oil systems can use two bottles of ZddPlus.) Also, the contents of the ZddPlus bottle can be split for smaller engine oil capacities. — This product is intended for Pre OBDII, off-road cars, racing engines, farm tractors, heavy equipment engines, etc.

Not safe for use with catalytic converters.
