If you like egghead stuff that's really useful, grab your favorite beverage and a snack and take a listen:

Very interesting and knowledgeable. Bottom line, buy the best oil you can afford with the appropriate manufacturer specs and use a fuel conditioner to keep the injectors clean to avoid oil dilution. I use Red Line fuel system conditioner which is one of Speed’s recommendations.

I'm normally VERY skeptical about bold claims about what someone should and should not do, especially when it comes to YT videos.
Other huge takeaways for me are:
Contaminants in oil is reason oil seperators go bad, which causes increase in crancake pressure, which causes all kinds of problems. Game changer for me; I will definitely change my oil more frequently.
Will also use fuel additives more frequently, will step up to at least once per month, versus 4X/year.
How those contaminents in the crankcase lead to more carbon build up on valve stems
Oil testing...I have an idea on how to be sure the results are accurate...will post findings in a few months.
Wear vs friction and zinc vs phosphate...Interesting!
