Re-posting this for posterity. I'm sorry but I can't imagine it requires a response.

Read his posts. It is because he only drives them for short trips and never races them. But this is a non-sequitur. You're responding to a point that was never made.

Re-posting this question because you dodged it.

Exactly the point.

Sulfated ash =/= EP properties.

Thought experiments are not the same as evidence.

How do you know this is even a significant hindrance for the 0w-40?
How much Ca does Mobil 1 10w-30 HM have, anyway?
Bench racing is fun and all, but if you're going to make bold assertions you should back them up with data.

Wow. You should write letters to Porsche, Lamborghini, Ferrari, BMW, and Mercedes. Tell them about this amazing insight before they ship even more defective engines! Thousands of customers are counting on YOU!

No, you weren't. Your original point was that 10w-30 HM was better.

Then, I'm sorry, but you have to concede that your entire argument therefore evaporates. Again, exactly the point. You can't look at a PDS, an MSDS, and a $20 VOA and immediately assume you know enough to know how the oil will perform.
