Today is the last day of my search for the "show me the data" to back up the Oil Filter promos on Efficiency Data. For me, "show me the data", is Beta Ratio results following SAE, ISO, and other national and international automotive standards bodies.
I promised to publish at the end of last month, yesterday. To be honest my day-job recently started sucking ~70 hours a week, cutting into my recreating time. In addition, some issues with "proprietary data" has resulted my changing the approach to parallel that of Consumer's Reports, which will get the results out, but unfortunately not the raw data, which was the original concept. This change has caused more grinding away in an attempt to fairly show the results. I will put the data up, hopefully in about a week.
(Edward Tufte has written 3 books on aspects of data representation, good reading. Following Tufte's thesis, I am intentionally biasing based on a known standard, which can be independently reviewed and individual judgment of legitimacy made. This bias is based on the relevant SAE papers relating filtration efficiency and engine wear.
I know that there are those who have an issue with repeatable, internationally recognized standards. They can do their own studies, and post them.
To wrap up, I have sent re-re-re-requests to all the companies' "customer reps" and "technical reps". If you wish to get a quick view of who has been responsive, google your favorite company's oil filter brand name combined with either "beta" or "efficiency." I have sadly noted that likelihood to provide at least 2 points of data is inversely related to your "google hit score."
