The chronology:
I sent in a virgin sample to Blackstone for the generally highly regarded Petro Canada Supreme Synthetic (in this case its 0W30 entry). Looking at the numbers I was surprised by the calcium, phosphorus and zinc...all seemed low. Blackstone was kind enough to retest...the new numbers were similar.
I contacted Petro Canada and they requested I submit a sample to them. He did tell me, prior to testing my sample, that he expected, based upon batch analysis that Calcium would be around 2230, Phosphorus 780 and Zinc 870.
I have summarized the information below. (I have a full analysis for only Blackstone and Wearcheck)
All samples were taken from the *same* bottle of new unopened oil.
Code:
Initial Blackstone Retest of same sample (Blackstone) In House Petro Canada Lab Wearcheck Canada
Calcium 1214 1196 2250 2015
Phosphorus 422 430 780 694
Zinc 572 554 940 814
