Testing is always questioned. As it should be.
Unfortunately, most people who scream the loudest have a reason for their question. Like their favorite
oil was listed as #98. Or they work for Royal Purple. Or whatever.
No lab testing is ever going to be perfect. It's never going to predict exactly what the
oil will do in
your engine during
your use. You have to evaluate the testing procedures and decide what makes you feel warm and fuzzy. Then put the
oil in your engine and run it for a while. After that, a UOA will tell you if made the right choice or not. Unfortunately, that kind of testing can get expensive.
I look at all testing with a grain of salt. And I look at all complaints about testing with two grains of salt.
I have never done a UOA on my Cobra engine, because I change the oil so often. But maybe I'll do it this year just to see what it looks like. I've done it for my other vehicles, and have found it to be very valuable.
