OK. Why?
M1 0W30 ESP vs. M1 5W30 ESP ?

Doesn't work like that here. You made the claim so burden of proof is on you. You just saying it's better doesn't necessarily make it so.

seems like HPL or Amsoil and others also has a better product than Mobil 1 you are talking about, and there is lots of evidence on their product on this site ,,,read and learn about you think you are talking about, and of course the purchase price along with application can be considered ,Mobil 1 is a relatively good product, depending on what flavor you like and the point is there are other brands that are perhaps better, being brand loyal or fan boy is not what bobistheoilguy is about, its about learning about and discussing lubricants

What is base stock? I tried to check SDS, it does not say. Also, what kind of additives it has that are better than what you can find in ESP?
And yes, "proven in real life," what ASTM is that?

For a start, since you are telling others what they should read, you might pay attention to the fact that Amsoil 0W30 SS and ESP 0/5W30 are made for absolutely different applications.
But I really want to hear the part where oil with HTHS 3.07cP should be used in engines requiring HTHS of a minimum of 3.5cP for what ESP is designed for.
Dickson's got a lot of hillbillies, esp. down at the Walmart, but we like it!
What do you think the applications of each are

ESP is euro engines, min HTHS 3.5cP.
There is nothing for me to think. SS has far lower HTHS.
Comparable Amsoil is 5W30 AEL.

Can anyone share their best guess on which of these oils might actually be the better option overall? In the past, I’ve mentioned that I assumed 5W-30 would generally be more shear stable than 0W-30, though I believe that was later clarified or proven otherwise.
So when comparing these specific oils, is there enough information to reasonably say which one stands out as the better choice? I’ve always understood that esters are considered among the best base stocks, and the 0W-30 clearly contains them. That said, could the ANs or other components used in the 5W-30 make it equally good—or potentially even better—in certain applications?
Just to be clear, I’m not looking at this purely from a cold-start perspective. Of course, in very cold climates, a 0W-30 makes perfect sense. But within the context of this thread, there have been differing opinions on which oil is actually the superior performer overall.

I really don't think it's possible. I'd opt for the 0w30 though knowing it does have some ester.
