So, I sent in an oil analysis sample, which I will post as soon as I figure out how to post an adobe file. Anyway, I sent in a note saying that 6 quarts went in, and about 4 came out. My report had 2 categories:
-Unit averages
-Universal averages.
What is missing? A correction factor. I am really annoyed that no attempt is made to correct for oil burning. For example, if iron is present in an oil with a full sump (6 quarts) at 15 ppm. If the EXACT same amount of Iron is present in 4 quarts of oil, the number would be measured at 20 ppm, or 33% higher, even though the total ware would be EXACTLY the same. I feel like I just wasted 30 bucks sending a sample into a lab that overlooked a fundamental concept about concentration and correction factor. Also, was the universal average for 15,000 miles or 3,000 miles. Why do I not see this defined. I want to be able to have some basis for interpreting the data myself. I am smart enough, however, to know that I don't know everything, so before I call up and ask for a refund, am I missing something? Thank you.
