M1 EP 5W-30 has a 1° C difference in pour point versus Castrol 5W-30--hardly a vast difference, but factually yes, a 1° C difference is less.

Perhaps in your locale, I have seen the switch up regularly, in fact on Amazon right now, it would take a Mobil rebate to come close to the price of Castrol.

That's a fair point of criticism, as Castrol's closest competitor to AP is their "Professional" line in the US, which is very difficult to buy at at reasonable price point for an average consumer.
What are the differences in real world results? I have not seen any UOA here that shows any major synthetic out perform another to any large degree.

Laughable since I use Castrol, Mobil, and Pennzoil. I took nothing out of context--I quoted you exactly and there was nothing non-sequitur about about my response to your post. Last, but not least, I am fairly that your expletive laced comment about a rebate was in your OP; perhaps I misunderstood your intent, but then again, I tend to ignore sarcasm from those who need to use those types of words to make a point.
