Hi all,

I am trying to find more detailed information about the Viscosity test values in the Napa Oil Analysis kit.  I believe that the test is run by Wix laboratories but not 100% sure about that.  

I use Castrol Edge 5w-40.  My recent test result 04.07.23 the value is 11.8 and it is marked with a Warning symbol.  My previous (which was the initial test) on 10.20.22 was 13.1 and it had a green checkmark.  

 

Does anyone have any insight or links to where I can learn more about the results?

Screenshot of the results? Usually there is a comparison average of units thst tell you where the oil stands in relation to others. Maybe yours has it? Maybe it Doesn’t?
