A customer recently emailed and had the question: is there a magic number somewhere on this report? They were asking if in any particular area, one number or result could tell them about the overall condition of their engine. Blackstone Joe thought this was an ideal time to break down the lack of an overall score/grade on our oil report, and why we instead opt for a much more comprehensive approach, breaking down the sample in its entirety and explaining why the results are high are low, and the reason why a high/low result may be indicative of a good result or a possible problem.
