I have a new performance-rebuild on my 1.8t VAG engine (331awhp) and am running the Amsoil European Formula 5W-30 for use in Minnesota. The Blackstone UOA shows 575 ppm [each] of both Zinc and Phosphorous. I have read that too much of either (in excess of 1,400 - 2,000 ppm) can actually cause wear. Analysis of your additive reveals Phos at 693,500 and Zinc at 148,600. Another Blackstone analysis came back with Phos at 130,780 and 127,480. My question is, to avoid pitting, how many ounces of your additive should I put in to get the ZDDP levels to 1200-1400?
These Zinc and Phosphorus numbers came from this and one other thread.
The reply I received follows:

Good afternoon,
One 8 oz. bottle of 99003-1 additive will increase the ZDDP content of five quarts of motor coil approximately 400 ppm. This equates to 1.6 oz. of additive raising ZDDP concentration of one quart by the same amount.
Thanks,

As you can see, this reply can't be reconciled with the conscious ions from this and other threads. I am very afraid to dump in the whole bottle and damage my new engine with pitting if the fellow that wrote me back is simply mistaken. Anyone here have any insights?
This VOA is 5 years old.
I suspect the ZDDP level has been unfortunately substantially reduced in the current supplement.
By comparison, the Red Line Break-In Additive contains 19,040 ppm of phos'. Therefore 1 oz will increase the phos' level of 1 quart of oil by 543 ppm.
What the Crane rep' says sound correct but you could always email him back and ask for clarification; i.e., how many ppm of phos' does you current additive contain? You could also mention a VOA from 2008 contains revealed approx' 130,000 ppm of phos'.
