Thanks for all the responses so far; now to answer questions:

That would probably be a 5w-30 HDEO, which will have an HTHS closer to 3.5. As you may be aware, I ran Delvac 1 ESP 5w-40 in my G37 for an extended period of time (the spec was for a 5w-30 in SM or newer with ILSAC optional) and am still running an HDEO.
I would gather you're considering one of the Amsoil options, and I would have no reservations about that over and above any other HDEO.
Not concerned about warranty [list of reasons here]; I agree that Amsoil's offerings are very good, but between my change in driving habits from more than 20,000 miles per year to 12,000 - 15,000 miles/year and their price increases, they've priced themselves past where I'm seeing the value in the SS...and I can get Schaeffer 9000 for less than the XL so that's the 5w-40 I'm considering. I made a mistake earlier, actual HTHS is 4.05.

It works great in everything in pour it into. I ran it for 17,000 miles last year in my 4.6 liter Ford with a Fram Tough Guard
I'm curious also, if this was one long OCI or if there was a change in there...and how much make up oil was added?

Wanted to pick the collective brains here for opinions, fact and speculation, so thanks in advance--
Is it SN rated?
Not specifically since it's a diesel oil, but it exceeds CK-4, which to my understanding matches SN.

As stated, right now it's a rhetorical question; but to give an answer, I'd like to maximize engine life. I'll likely end up running 5w-30 or maybe even a -20, but am interested in testing the waters and running each oil to see how they do.

Me, too...winter? Is it garaged or have a pan heater, or just started right up when it's cold?
