My 2012 Frontier specifies it for summer use.
It is not obsolete as Mobil, Pennzoil, Mag1 (WPP), and many others still blend it.

Now look down, right next to the rolls of fax paper.
Hey, I still have a fax machine, connected to a landline. Actually use it every few months. But it's also a copier and a printer, so no rolls of fax paper for that one.
In a really old car like from the '80s or '90s that was spec'd for a 5:30 or 10:30 I would have no trouble running the 10w30 especially with how much advanced even the premium conventionals are.
What were those machines called before they were called fax machines? I thought it was like doohickey or widget or something weird like that. I know we have one at our other house but I think we've only used it to make a copy of another piece of paper or get a bid request on bulk materials.

Your maybe thinking of a telex machine? Even before my time, which is saying something.
My sister who is 10 years older than me got a secretary job in "town", and I remember her describing using it over dinner. Everyone was in awe in its abilities, or so I recall. I was likely around 9.
10w30 Havoline Lifelong is still $21 for 6 quarts while 5w30 is almost $30. Tempting to use in my 5w30 vehicles, especially in the South.
Though the 80s and early 90s I still saw catalogs and advertisements with "TWX" numbers. TWX an abbreviation for Telex.
Never heard of that brand but if it's good stuff send it to me.
In the winter temps we get around here it'd be fine. Not so sure about a place like International Falls, MN.
There is a difference between obsolete and obsolescent.
Obsolete means the use value of somethnig is not high enough to justifiy using it even if given free in perfect condtion.
An example is a WW1 batteleship.
No modern navy would choose to operate it given the high costs for as little combat power as is gained from its existence.
Other examples: A civil war machine gun would not be operated by any military even if given free.
Obsolescent:
If someone were to make this new today it would be made differently, but this device still functions and if given free people would happily use it as its use value is not exclipsed by the many, fueling, maintianing effort for it.
Examples: A perfect condition 1979 Mercedes benz S class, Luger P08 pistol, MP 40 submachine gun, an early mark DDG51 destroyer.

I think it debuted about 70 or so years ago. I ordered a 6 qt jug of Valvoline Maxlife 10/w/30 from Amazon on 12/22/22. My buying history says it’s the 6th time I have ordered it. My Walmart still stocks it but buying from Amazon keeps me out of a Walmart. Could it be safe to say it might be the most popular multi vis oil ever? IDK.

That grade (10w-30) is not "obsolete". As long as there are old cars still in use which were spec'd for it, it will have use.
Obviously, it's not a grade that has any common application in typical PCMO ICEs today.
It has become somewhat common in HDEO applications today.

Been using it in my 3.7 F150 for the past 72k miles, just hit 223k zero issues. Every 5k, not obsolete to me.
The first ones we got at work still used the heat sensitive roll paper. They were still called Fax machines though. Xerox I think, was the brand.
(edit
Oh yeah, they still had the audible modem connection over a landline.Haven’t used it in over 10 years. But I saw Pennzoil 10W30 on the shelf at the Shell gas station just this morning.
