Craig why not XD 0W30 or even 0W40?
I've used XD3 15W40 and thought it did a pretty good job. It was my ARX carrier oil several years ago, and for a variety of reasons I used it as a summer oil instead of GC year round last year. I have nowhere to get XD3 0W30 but I can get XD3 0W40 at Walmart.
I'll check it's numbers again, but I have one possible concern going in to XD3 synthetics. M1 0W40 was definitely noisy in my BMW M52 and it was not a "slight" placebo effect. I ran it for 50,000km or so before learning better and switching to GC for relative silence.
I'm concerned that the "M1 noise" everyone posts about, and which I've read about and observed with other non-M1 oils, is actually a function of XOM PAO base stock. I'm reasonably certain that XD3 0W40 is PAO based, and I could end up with the same noisy base stock as M1 0W40 since it's an XOM product. Yes, it's all conjecture and I freely admit that, but I've read reports from people running T6 reporting exceptionally smooth and quiet operation.
