Each 4 oz bottle of ZDDPlus treats 4 to 5 quarts of oil, restoring the level of ZDDP back to the SF designated level of 0.15%' a level of ZDDP that your older performance engine was designed to have and is required to prevent excessive camshaft, tappet and valve train wear.
What is ZDDP
ZDDP is a surface modifier that prevents metal to metal contact. It is a highly effective extreme pressure lubricant used in high quality motor oils since the 1930s. Recently ZDDP has been removed from motor oils. The reason for this change is that the EPA requires catalytic converters to function effectively for in excess of 100,000 miles. Since ZDDP can slowly impair catalytic converter function especially in engines that burn oil this highly effective additive was removed. The loss of this additive was not deemed a major problem for newer cars.
Why do I need to add it to my oil?
ZDDP is required most where pressures and wear stresses are the greatest. Therefore, it is absolutely essential for older, high performance muscle car engines as these are equipped with high-lift camshafts that produce high rates of valve opening, flat tappets and high rate performance valve springs, all of which increase pressure and wear stress.
The EPA just didn't consider the classic car enthausiast when they decided to pull ZDDP. Furthermore, since these classics never had catalytic converters the removal of this additive from their oil will have no positive environmental impact ...... in fact it will probably have the complete opposite effect as the accelerated valve train wear will most likely result in ill running, smog belching motors!
