I know i know Jay, it is not 100% to believe it if you check the oil by fingerfeeling but at least if the oil gets contaminated or brakes down you will feel something by finger (not 100% but at least 50%). I know when i had another car i was using very cheap mineral oil, after 2000 miles by fingerfeeling you could feel very little viscosity in that oil. The oil was exhausted. This full synthetic oil is completely different. -The viscosity of the used oil and the new oil is completely the same.
It becomes black after few hundred miles, it is totally not important according to me. It is from the smoke in the combustion chamber. The PCV system takes it away to burn again and a very small amount will get mixed in the oil.
I am telling you boy this issue of changing oil is completely fake and the reason is to win money if there are people who believe their story.
