Can anyone here definitively state that one oil underperforms and one outperforms. Ater 23 years of reading BITOG I have yet to answer this question..
Oil is Oil

Thay are pretty much all the same at any given price point the question is will we notice the difference and the truth is unless there is a design or quality problem most engines outlast the vehicle if cared for. [Sticking with the major quality bottlers]

Oh boy. Here we go. 
"Oil is oil" is perhaps the most autoschediastic phrase in all of lubrication, often proffered by those who know little to those who know even less. It's equivalent to saying "steak is steak".

Yes for me every 6 months or 6,000 miles… drain and refill. It all goes in and comes out the same, No matter how much you spend.
As your filthy expensive consultant says, "That depends..."
Here is what I think. Within the confines of an adequate OCI with an adequate filter and typical driving habits with a properly engineering and built engine, all oils meeting a certain specification will provide similar function. So, in that regard, oil is oil. You need to get to the fringes or outer limits of OCI or driving habits to see a difference.
Huh? Water is not oil. And it's assumed we're not talking about salad oil.
There is a difference, its all described on the home page. I suspect for a normal daily driver passenger vehicle you won't see it till maybe a 15K OCI, possibly more?
Personally I think contaminants and wear particles in the oil are a far bigger problem than the oil breakdown itself.
I like the 3 packs of mobil 1 walmart mistakenly sells for $24.47

far as modern engines are concerned 90 percent of the time if you use the correct grade for your climate you will have years of good service. i would find brand a personal preference mostly.
This is just another rephrasing of "what oil is best?"
Bob?
Tony?
Where art thou?
The answer is and always will be "it depends" and the question is terrible. If you run any oil in a engine for 1 minute, probably doesn't matter. Go 100 hours, maybe some differences start to show up. Go 1000 hours and tell me all oils are the same.

In other words you can't answer the question.
