Over the years I have performed UOAs on my personal vehicles.
Those tests have not shown one engine oil to be better than the next, or from one with a different viscosity.
The price of my oil changes is the cost of the oil and filters only.
My question, is the purpose of UOAs for the purpose of extending oil drain intervals or preventing wear to contest engine oils against each other?
I simply watch the additive package and 100C viscosity degrade over time and use, and go from there.
