So I was talking to the guy and he said that they don't test for fuel dilution unless vis drops below the grade. So, on pilot i run 0w20 M1 and vis was 7.2 and I told the guy that there's no way oil just sheared in 3k that badly. He said alright, we're going to re-test both sample for fuel dilution (they keep oil for 30days). And here we go:
So question is: WHAT THE [censored]?????
So, what was initially a big problem is now no problem at all? And what wasn't a problem at all is now a pretty big one? Makes you wonder about that value of UOAs at all: there's a limit to the precision we should expect from a $30 test, but this calls into question the whole process. How can a machine-based test show this level of variability?
And the test with the greatest loss of viscosity has virtually no fuel dilution. You weren't buying th conclusions in the initial UOAs; I'm not sure I buy these. Maybe the best strategy is to forget about UOAs, behave like ordinary people and just be happy.
