Castrol 0w-30 is close to 0w-40, and is LL01, which is good.
There is NO way I would use a 0w-20 in these cars, no way.
20 weight is no where near the 30 weight you need for your E39.
IMO, 0w-20 is only out there because of the governments BS of trying to run more efficient cars.
Jason, you should definitely read this article by Aehaas on oil and oil viscosity, I think you may have a different opinion about 0w-20 after reading it....I do. I am still unconvinced I will use 0w-20 outside of a manufacturer recommending it, but Aehaas makes a good argument for it: http://www.ferrarichat.com/forum/faq...=haas_articles
