I think the youtube guy vehicular diy runs t6 and hes got almost 200k miles on his N54.

I run the T6 in my diesel truck, and it's got 250k miles on it.....the Blackstone Labs oil report I did on it looked fantastic. Rotella T6 is a great oil.....since it's the correct weight, I see no reason to not run it in my N54. I'm planning on turning a sample into Blackstone Labs here pretty soon from my 335i.....so though should tell me all I need to know.

Nope. If anything, it's got more anti-foaming additives than other oils since it's designed for diesel motors and their high pressure oil operated (2,000+psi) fuel injector systems.

How does the fuel system pressure have anything to do with the oil foaming...?

That's oil pressure that's runs the injectors.....the oil pressure is around 2,000psi. You need additives to keep it from foaming.

Fuel system pressure wants to be just a touch higher than 2000psi
