In a nutshell by Mr Ken, since I'm utterly useless at techincal:
 
Oil pump has fixed displacement and will pump the oil towards the internals at the same rate regardless
The interesting part is what happens once it gets there
But before that we should think about the oil filter
If the oil is anything higher than 5w-XX then a lot of it doesnt even get filtered while the oil is cold
The filter creates a restriction and there will be a pressure drop between the inlet and outlet of the filter, just as if the filter was partially blocked 
That means the filter bypass valve opens and sends some of the oil through unfiltered

So thats problem no1. When the cold oil reaches the bearings, it hits another restriction. This affects the actual oil system pressure (which has nothing to do with the filter anymore). The oil tries to squeeze through into the bearings but its hard because the oil is still thick
 
So the oil flow through the bearings is not great and the pressure goes way up. This opens the bypass in the oil pump in order to regulate the pressure, and sends most of flow back into the sump. As the oil heats up it thins out, until eventually the valve closes and then pressure starts to go down

If you run a 0w or 5w you get full flow through your bearings from the beginning, and if the hot viscosity is around 40 or 50, then in theory it wont get much thinner when it heats up. A 0w50 stays almost the same through the whole temperature range (in theory)
And thats where it gets a bit iffy. In order to achieve a really wide viscosity range like 0w50 they need to use viscosity modifiers and **** like that. And I'm not sure how well they hold up over time and high heat and high shear conditons. Its generally accepted that the most stable and durable oils have narrow viscosity ranges. Racing oils will often have only one number instead of a 'range'
 
Any takers? LOL

Less reading of wizardry, more using the correct oil for your engine.

Okay tbh I never finished reading past chapter 1 lol but for now I'll stick with 5W since it's half way between 0 and 10. Just thought it would be an interesting debate tho
I suppose you could call it a list hehe but most of it isn't actually performance related. Would be good to see how far I can take this car in full road trim and if money and time permits the engine will be "bulletproof" without even touching the internals
