I do not believe there are any 0W20 or 5W20 Euro approved oils by VW, BMW , Porche or MB - correct ? If correct - then why are only 30 and 40 weight oils able to meet Euro oil specs ? Based on potential , likely answers (beyond CAFE) either the USA cares more about gas mileage / fuel economy than Euro vehicle makers or Euro vehicle makers don’t think a 20 weight oil can hold up to maintaining engine life standards they have set forth for their vehicle brands ?
Why No 20 Weight Euro Oils ?

That is not correct. There are several, including those with a Porsche, VW and Mercedes-Benz approval.
All include a minimum HT/HS as part of the approval.

Incorrect. Thread closed.
No cafe related mandates. So no unholy quest for cafe.
Euros care way more about fuel economy with their 5 to 10 dollars a gallon gas pricing but they care more about cars lasting a long time.
What are you talking about? First off, if the vehicle is being sold here in the US then it does have a requirement for the oil from the EPA.
And beyond that, all EU nations and the UK (as well as many other nations including Asia) have CO2 emission requirements that require specific oils to be used that were part of the initial emissions testing.
Yeah the epa says a lot of things that should be ignored.
Fine, but it is not "No cafe related mandates. So no unholy quest for cafe" as you stated earlier. As I noted above nearly all European manufacturers have a 20-grade approval and it is absolutely due to regulations.
Its the OEMs unholy quest for cafe.
Until the government dreamed up cafe probably during an acid trip virtually no one ran 20 weight oil in vehicles since the advent of multi grade oils.
Thought the first Mobil 1, invented back in the 1970s, was a 5W20?
Correct.
Mobil 1™ history | Mobil™ Motor Oils
Mobil 1™ motor oil was introduced more than forty years ago as the first globally available fully synthetic motor oil. It remains the world’s leading synthetic motor oil brand.

API grade requirements have changed multiple times since then. Although HT/HS hadn't been invented back then this oil was likely near 3.0 and not like today's 20-grades. It was sold as a replacement for existing 10W-40 oils.
I stand to be corrected - never seen but the 5W30 version before … Still , probably more Euro vehicle makers spec 30 and 40 weight oils for their engines versus USA auto makers .Readily available at your local Walmart.

Where are you getting your information?
Any idea/thoughts how that was marketed upon release as far as being "better"?
"Our new 5w-20 is 50% lighter than our 10w-40 which means more MPG and less fuel fill ups!" I'm guessing, especially with the beginning of the oil crisis happening...
If you actually look at VOAs on a lot of the 20 weight oils they test out at around 9cSt, where 20 and 30 weight oils overlap. They could go down to around 6cSt but they don't.
(Edit: that's 9 and 6cSt at 100c)
I'm unfortunately old enough to remember what rubbery 10W40 VIIs did to the inside of oil pans... And tops of cylinder heads... And everywhere! Talk about clogging up stuff!
I think there's a fair number of economy/compact, non-high performance Euro vehicles that can do just fine on XW20 oils. Not everyone is blasting down the Autobahn at 150 (MPH)!
