CAFE is the correct answer to the OP's initial question.

I can find nowhere in the manual about using a different viscosity than 0/20 for our '19 Corolla.....other than "5/20 may be used but must be replaced at next oil change". Not a word about anything heavier under any conditions.......unless I'm missing something.

The vague statement that "a higher viscosity may be better suited if the vehicle is operated at high speeds, or under extreme load conditions" (even though they warn elsewhere of supposedly dire consequences of modest overloading) is in my 2011 Prius manual. Other people have posted about it being various newer Toyota manuals, I believe.I can find nowhere in the manual about using a different viscosity than 0/20 for our '19 Corolla.....other than "5/20 may be used but must be replaced at next oil change".

I just always use what’s recommended that’s what I was taught to do and that’s what I follow.
I’m sure Uncle Fester done a lot of that.
When people get on here and act oblivious to the CAFE mandates, whether it be out of simple ignorance or willful ignorance, I don't have any problem pointing out when and where CAFE is at work.For some here, heads is correct.
People think they’re geniuses, they want to make motor oil into quantum mechanics but in reality they just have too much free time.What gives everyone the idea modern engines are so oil grade sensitive?

That in no way equates to CAFE "being in my head".
Bad fail. Try again.
Try again.I rest my case.
big if trueThere's Border Patrol vehicles that have >400k miles on them with 5w-20, at 20-25k mile intervals, and some of them idle for as much as 10 hours a day in the >100*F heat.
Lets see those border patrol vehicles deal with 10-20 cold-lukewarm restarts.... aka soccer mom bus'ng those kiddies around along that 'northern' border. That is the real test, you know, all that freezing cold weather/snow/slush from that southern border climate is such an engine restart killer
Can't stand when someone mentions what a 'fleet' can get away with, like taxi gov't or magazine tester....
Vehicles with 400k miles means nothing if the engine is replaced 5x in those 400k miles hint hint. Seen it too often in gov't fleet vehicles and many GSA auctions where the drivetrain is toast below 100k miles. But, certain conditions are amazing with what some vehicles tolerate. Too bad those are too far and few in between the failures.
Some? lolWe got taxis here still running with 500k+ miles on 5w20. How much more can they do if they ran 5w30 or 40?
