kirban 2 cents worth
ronbuick above hits the nail on the head....unfortunately it is getting harder and harder to find the older oil.
Our source was able to have the break in oil from a new 2007 Corvette ZO6 analyzed....owner came into the Chevy dealership with a mere 400 miles on his new ZO6....that oil from GM contained 3,000 ppm of zddp....3,000 ppm...the new Mobile one that he got in his first oil change has only 800 ppm....
I doubt that motor was even broken in at a mere 400 miles.....
I put a bottle of ZDDPlus in every oil change in my mid 1990s cars because back then concentration level was still at 1,200 or 1,500 ppm....it has virtually eliminated any valve train ticking I would get on a cold morning on initial start up.....
Not to mislead anyone it is not a cure all if you have valve train ticking for years but remember things happen gradually.....making it difficult to recognize certain things.
marketing is very clever....ask your wife she knows cereal boxes cost more and may be smaller in size slightly. Candy bars have shrunk...those 5 cent mints are 25 cents and a different size....they do things gradually had they gone from 1,800 ppm to 800 ppm over nite, the issue would have become known instantly...as it was it was engine rebuilders who first discovered the issue and in the beginning some of the issues was blamed on poor quality cam shafts, from china....which I am sure was part of the problem.
Then they initially thought and cam companies agreed it was just at break in you needed a heavy dose of zddp...comp cams has a product guess what that formula is 4 years old in that additive they market which was great when the oil was SG code....
Why you don't want something marginal is because zddp depletes at a faster level for the first 1,000 miles of driving.....one reason you want 1,600 to 1,800 ppm...
For those that want more exact info we have over a dozen tech briefs available written by someone far more knowledgable than me. Send me a pm with your address and we would gladly send you the info.
The high pressure points in your valve train the harder it is on your cam shaft etc.....in other words grand ma driving her small V6 to church on sunday may never have any issue in her lifetime....they have never found anything better than zddp as a lubricant to protect extreme pressure points.
My source now has a production paste available for assembly of the valve train and we have production samples in the hands of several major engine shops to try.
That product has been tested now for 6 months before it was released and has proven to be better than any nationally marketed valve train paste.....including Joe Gibbs......

From a Buick standpoint we are very fortunate that the product has been produced by someone who owns the largest turbo buick collection in the world our company is just the main distributor......
