Is there anything they require over there that we don't? Or something we have that they can't? Or is it just a selling point for people who think anything made in Europe is better quality?
If anything the Europeans are playing catchup to the American & Japanese who have been at the forefront of low viscosity for two decades now.
Why does a Ford Focus in Australia spec 5W30 while the same engine in the USA model specs 5W20?
Really? Tell us how and why all those manufacturers use heavy ACEA oils elsewhere? ItIf anything the Europeans are playing catchup to the American & Japanese who have been at the forefront of low viscosity for two decades now.
Take a look through the attached Afton Oil Specification handbook (sorry, this is 2014, it wouldn't let me upload the 2019 version, it's too large) to get an idea as to the testing protocols employed in the European certification process.Is there anything they require over there that we don't?

It was not only HTHS. There is fundamental difference between API and ACEA. API is lobbying arm for oil industry not car manufacturers. ACEA is organization founded by car manufacturers. They are opposite in their founding goals who the protect.ACEA in its current form was founded because european manufacturers were scared of API energy conserving oils. 3.5 min HTHS became the standard overnight and still is to this day.
ford was the first to rebel and that’s how we got a1/b1 and a5/b5. other manufacturers slowly came to accept there was a time and place for fuel economy oils, the c5 segment is growing rapidly
The ACEA was the first with regards to the adoption of industry wide long drain intervals combined with the performance requirements of significantly higher highway speeds (>100 mph).Is there anything they require over there that we don't?

BMW does the same thing. The spec for my B58 engine is 0W20. In Europe, the oil spec is 0W30.Because the United States is the only country that has to deal with the stupid lunacy of CAFE. Going beyond that, Toyota specifies 0W-16 for their Camry's sold in U.S. market. The same vehicles with the exact same engines sold in Australia and other countries can use up to and including 15W-40.
While technically correct this is fundamentally incorrect. European countries track emissions (ex, grams of CO2, NOX, etc) and iirc consumers also pay a tax based upon the emissions of the vehicle.Because the United States is the only country that has to deal with the stupid lunacy of CAFE.
No autobahn in the US and the vast majority of BMWs in the US are used to tool around town, to/from work, soccer field, grocery store.BMW does the same thing. The spec for my B58 engine is 0W20. In Europe, the oil spec is 0W30.
