^in my wife's application, OEM recommends the 0-20 but for ROW I think it's 5-30.
The video goes through 4 parts.
First it tears up the ai video.
Second it shows how info can be skewed if one compares break in miles <10k vs. >10k in different weight testing.
Third it shows 0-20 holding up just fine compared to 5-30 post 10k.
Fourth it shows diesel showing less wear with some higher viscocities (the reverse of the gas engines).
For me- it gave peace of mind in my wife's car with 0-20 (that my old crabby self would consider a "fleet/epa mpg extender at the expense of engine longevity") weight.
My inner self wanted the 5-30, but the warranty wants 0-20. Especially "bob" the oil guy who talks about "fracting" oils and how the high range multiviscocity oils can break down rather quickly in lab testing, even the mere mention of 0-20 scared me. This 0-20 video helped me sleep a little better at night with real world data and not potentially voiding warranty.
I'm so happy, I might even concede that CP was right about the lower weights.... 
naw...
I like lake speed jr. . His energy reminds me of a jack russell terrier. Heck, he should probably run several laps around his yard before making a video, but his info is amazing.
and it looks like about everyone here is already subscribed- so I'm late to the party
