Many $7qt of oil can easily handle this. All of the Mobil 1 line in fact.

Mobil 1 themselves confessed some time ago that group 4 and 5 basestock are too expensive to produce, that's why they replace them with a cheeper product invented by them called Visom
IMO Mobil 1 nowadays is a group 3 ¨synthetic¨, long way far from Motul 300V series
Wrong. Technology changes and the new Grp III+ base oils rival PAO and in some areas exceed them (solvency).
Mobil 1 is a mix of PAO/III+ and V base oils.

I don't say Mobil 1 is a bad oil, I only say that there is no fair way to compare it with a true synthetic, top-end racing ester lubricant like Motul 300V, M1 is good for what it is, but it's not a first class racing oil like 300V and it is ridiculous to compare them.
Do you intent to convince me that a product that costs 3 times less than other product can be equally good, because if you do it I go out.
Mobil 1 makes racing oils, usually similar chemistry but with higher levels of ZDP. Mobil 1 0w40 is also considered a racing oil.

only enterd in this thread because some people said they will always take M1 0W-40 over Motul 300V 0W-40 and I think that's ridiculous.
No, you're ridiculous. Mobil 1 0w40 is tried and true and has more approvals and testing behind it than Motul 0w40. It's also filled in many high performance cars.
What can be explained to someone who consider that the approvals an oil has are a demonstration of how good it is...
No REAL racing oil has any ACEA or API approvals for many reasons, if you don't know EVEN that it's useless to keep talking.
