Thanks as well, but yes, I've seen those, and that's why I was asking for more recent ones, since XOM tends to change things, sometimes more often than that time frame.

Thanks again, but I was looking for some specs because I wanted to add just ONE quart to my current mix (after quickly draining a quart out) to thicken it up a little (for the warmer weather, until I do a full change later in the spring/early summer), get rid of some fuel dilution, and add back some TBN and depleted add pack elements.
The M1 was on sale at NAPA, so that's what I went with.
I AM trying to convince my brother to put either this, or the Castrol 5W-50, into his '99 Boxster IF he ever does another oil change on that poor, abused thing (LONG story).
