.....shows that Group 2 countries use thin 0w20 low-saps oil if it has a particulate filter (PF), and thick high-saps oil if no PF (just talking about single-turbo engines).
Porsche never said to use VW 504/507 thick oil for single-turbo engines.
If you have a link for them saying that, then by all means, supply us with that fact. Otherwise, these are just guesses.
I do personally see the reasoning that says we can use thick oil anytime we want though, its just that Porsche VAG never says it.
To me, it is indeed a matter of gasoline sulfur content to say if you can use a low-saps oil. In the U.S., low-saps should be fine since sulfur is now way down. Valve stem deposits ostensibly less with low-saps too.
And the question of thin vs. thick is a matter of single-turbo vs. twin-turbo. Singles get 0w20, twins get thick oil. Bottom line.
You answered the question.
My vehicle:
GPF; VW504.00/507.00
no GPF: Porsche A40.
Under no circumstances VW508.00/509.00.
Of course, anyone can do anything with their vehicle. heck, they can run Dollar store oil. But make no mistake, 0W20 is there only for one reason: CAFE.
