Wow, this is a whole lot of churn just to sort out what goes into your grocery-getter.
There is a dirty little aspect no one mentions here (because they may not be aware?) The formulation 'meets the spec', yippee. Pop open the bubbly. Does the batch in the bottle meet it? Are you buying from a company that plays the 'test until you get a pass, then put that on the CofA' game? What are their data handling guidelines for replicate results that are outside of acceptable test precision limits?
Since no one I know of gives you batch data unless you buy in bulk, you may be buying a pig in a poke.
Lamont, I have a question, if I am choosing between 2 oil's and they both have tests is it fair to say that these tests are just pure Marketing to try and get me to buy there oil.
Would it be better to compare 2 different motor oil's by looking at each motor oil's PRODUCT DATA SHEETS.
I could then compare 40 Degree Celcius and 100 Degree Celcius Numbers
I could compare Flash Point and Pour Points.
I could compare HTHS Numbers as well as how both oil's do in the so called Cold Pumpability Test.
