SAVE CAMSHAFT FROM EARLY DEATH

In recent months i have found a need for ZDDP in engine oil due to killing a cam shaft.I have found a lot of information on the reduction of zinc and phosphorus in oil it is a slow killer you would never expect it till its to late. At the most risk is the classis car engines, We have found that all cars and trucks 1990 and older need more zddp than what is in sm and cj-4 oil. Even 2010 and older VW, AUDI, MINNIE COOPERS are not safe as well as 2007 and older DIESEL cars and trucks. I have found a web site that has very good TECH breifs to inform all about oil things and the product usualy shows up in 3 working days. Go to www.zddpus.com they sell zddplus and evrey thing over 1 bottle shipes for free. The Disel engines use 1/4 to 1/3 oz per gallon of cj-4 oil and if you usesm oil 4oz to 4 to 5 qusrts of oil.
