No engine noise for 2021 5.0l

[Milton]

I've been monitoring Oasis to see Tsb 20-2023 (diesel like engine knock at idle) to be extented into 2021 MY as Ford did in 2020. There is no change to the 2021 gen 3 coyote that I can see yet the Tsb doesn't cover this year. What did Ford change to repair said "normal operating characteristic of the 5.0l engine". It would seem to me that Ford is aware of what causes this noise, corrected it but isn't disclosing that information for the effected vehicle of 2018 through 2020.
How many members have this condition? BTW it's not and can not be mistaken for the typewriter tick which has its own tsb that has been extented into 2021.

2021 started recommending 5W-30, all I know.

Yes noticed that. I have been using 5w30 since first oil change. Consider daily hiway commute track use.
