Again, no component is lubricated by flow. You can have no flow and a part is still lubricated.
You are really struggling with this. I’d suggest you learn some things prior to making statements as you are doing here.
Mobil 1 too many varieties

Lucky for you, you got an even better oil by accident. You should keep making the same mistake for future oil changes.
Not too sure about that. People pay more money for Iced Coffee. Less coffee and more water. Never understood that. It's marketing genius!!! I myself do not pay for Iced Coffee.

I buy a McDonald’s hot coffee for $1.29 and turn it into an iced coffee
In the summer they sell McDonald’s iced coffee for $1 so I get a lot of them then. But otherwise you’re right, it’s a rip off paying more money to get less actual coffee. Half of it ends up being ice. When I do occasionally pay full price for one, I ask for very little ice. I know all the tricks Are you George Costanza?

Yes! That is corperate America.
Sure, I still learning a lot of things about the oils.
That's true there a lot of machines that get lubricated just by splashing oil around.However in 4-stroke car engines crank bearings, rod bearings, pistons, camshafts, and VVT are lubricated by oil under pressure which means oil flow.
How would you comment on this one, the last statement reads:
That’s something all right. You got me.
Actually, part of Costco's business model is to offer consumers 'less" choice and only offer one or two options for a majority of their popular items. I would tend to agree with RooflessVW in principal. Too many choices often leads to buyer hesitation and confusion. Outside of specific viscosity and and high-mileage options, I feel many manufactures allow their marketing teams to go crazy. Having a few solid options would make it much easier for a consumer IMHO.

Costco has taken things too far in that direction, which is why it’s not a good place for oil lovers like ourselves to shop. Nowhere near enough choices

Again, unless the pump is on the relief, the "flow" is the same. Bearings are self-pumping, oil is supplied to them under pressure and they draw what they need from the pressurized galleries. @Shannow (ME, expert in bearing design) has written on this extensively in the past if you search his posts.
Yes, oils are slotted into SAE grades using a standard test that measures flow under gravity at 100C. This is not meant to imply, nor are you meant to infer, that this is correlated with how an oil moves through the engine under pressure; it tells us nothing about the application. Just like this doesn't tell you how the oil performs at -30C, which is why we have the separate Winter grading system, or specifically how well it performs under high shear conditions, which is why HTHS is a parameter that many OE's mandate a minimum spec for. It also doesn't tell us how volatile an oil is, hence Noack. These are properties of a product under specific test conditions, which have varying degrees of relevance and which may be overridden by specific OE approvals.
300gr is a property (mass) of a projectile. But I cannot infer how that projectile behaves in service; I know nothing about the application, without information such as what calibre it is, what cartridge it is being fitted to, what rifling there is, if there is rifling...etc. An ILSAC 5W-30 can perform quite differently from an A3/B4 LL-01 A40 5W-30, even though both are 5W-30's with the same grade on the bottle; they are both 30 grades.
You’re more patient than me
I thought of this thread the other day while I was at work. I had a customer who was having a hard time deciding on oil. They weren't sure if they should go for "Truck & SUV" or "Extended Performance High Mileage" (no Dexos cert) or "Extended Performance" (with Dexos cert) or "Advanced Fuel Economy" (it was a high mileage Tahoe that took 0W-20). Because obviously if you have a high mileage GM SUV you want the best performance, the best fuel economy, something designed for trucks, something designed for higher mileage vehicles, and something with the automaker approval your car asks for... all at the same time... which if you go by Mobil 1's labels, none of their oils can meet. On the other hand, since literally any of those oils would have been totally fine for their vehicle, it goes to show that there is no meaningful difference between any of them if used at the OE recommended intervals... so it's all marketing BS.
In the end they went with the Extended Performance but having so many varieties made a simple decision confusing. Yes I understand how marketing works and shelf space at retailers matters and even if they lose 1% of sales because people are too confused they probably gain 5% of sales by taking up half the aisle (and if they don't, someone else will), but I really do wish it was a simpler time in motor oil with less similar products to choose from.

Pretty much why I use ESP 0-30 in all my cars now. There would be very few cars on the road for which it wouldn’t be an acceptable oil.
the stuff is not designed for modern day direct injection engines.
fine for older stuff

It’s perfectly fine for modern DI engines. Tell us why you think it isn’t….
This is not true.
It's perfect for modern engines and its approvals confirm that.
