I recently analyzed a database of more than 30,000 oil analysis reports from diesel engine samples (Class 8, long-haul trucks). With so much information at my fingertips, I was like a kid in a candy store.

Today’s database software products empower users with versatile analytical tools that can rapidly search, sort, graph and statistically analyze data. With the right queries, one can turn huge amounts of raw oil analysis data into new interpretation guidelines, fault trees and rule sets for the oil analyst.

Naturally, after a couple of hours of slicing and dicing this rich database, I discovered many interesting facts. One such fact relates to copper. In diesels, copper is second only to iron as the most abundant wear metal.
