As you keep pointing out, TGMO's got most extraordinary VII characteristics, which is a little different to CG...wouldn't you say ?
After all, your blend was ONLY because you couldn't get M1 0W30 in Canada at the time...not because it was ideal.

As I suspected you're just being typically argumentative as you don't have a case at all.
As per ASTM the difference in base oils doesn't matter, GC don't contain any moly so that doesn't matter and I don't see how the difference in VIIs matters and it doesn't matter when mix with M1 and the PPDs may not be different at again as if it matters.
And thank-you for informing me of my motivation for the TGMO/M1 0W-40 blend. But the truth is that I just took advantage of the fact that M1 AFE 0W-30 wasn't available in Canada (until recently) to have a frank discussion with Mobil (Imperial oil) about the suitability of blending their PCMO and HDEO 0W oils to make an appropriate 0W-30 similar to AFE 0W-30. There is nothing like an obvious gap in a companies product line to get a less guarded honest response.
In that discussion it was uncovered that there were no issues in blending any of their 0W oils or any Mobil oils for that matter.
