The Castrol product meets basically all the same specs and is almost as equally available. That's why I've mentioned it in the thread several times already. However, the other two products are not the same grade and are subsequently irrelevant.

I really don't think you do. I've used Mobil 1 0w-40 in my M5 (and it had twice the number of cams) when it was -30C, that's the CCS limit for the 5w-xx designation, let that sink in for a second. The CCS (cold cranking simulator) limit for a 0w-xx oil is -35C and you are telling me you notice a difference at -20C, 15C ABOVE where the oil is tested? Come on, even Stevie Wonder could see that elephant in the room.

Anecdote. I had no sound, in a 400HP car with 11:1 compression, with it, PU 5w-40, or the OEM BMW 5w30. Sound means nothing unless somebody has specifically solicited your opinion on that matter, which they haven't. This thread is a general discussion.

Seriously? The oil that is good enough for Mercedes and Porsche in the 24hrs of LeMans isn't good enough for your car? What does your engine "say" about that?

But IMHO, Castrol 0W40 in better suited for my car and my needs (starting car on -20.-30 at 12,000ft).
Both are equally suited because they have the same bloody approvals, the difference is that Mobil actually provides their MRV numbers, Castrol doesn't. But both are required to be within the limits.
Basically, personally you PREFER Castrol, and that's fine. I PREFER Mobil. They are both excellent products and equally capable. Generally, the Mobil product can be had cheaper and is more available. It has BETTER availability. I consider both products interchangeable and while my preference is Mobil, I make no claims about the Castrol product being inferior in any way.
Well, considering you have double number of camshafts, I suppose to figure you are better equipped to tell the difference.
I already told you, Castrol 0W40 (or 0W30) suits my needs better. But, apparently having 4 camshafts and 11:1 compression ratio makes you better informed.
When it comes to cold cranking capability, again, I would say that even Mobil1 5W30 ESP I used behave better. Why? Maybe Castrol and ESP have more Ester that sticks to the moving parts and they stay longer there, IDK< nor I care, I know it works better in cold then M1.
I get your point, but again, i trust my ears more then Mobil1 (not that I trust them at all in the end, it is again EXOM, or for that matter BP).
Again, it is good oil, I used it a lot, but not king of the hill.
