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:
Factory M-Sport package with factory installed M-tech bumpers, factory Bluetooth, factory M-Audio 10" dual voice coil subs, Homelink, M5 rear stabilizer bar, Bilstein B14 PSS coil overs, Stop Tech ss brake lines, Akebono Euro Ceramic brake pads, oem Brembo and Zimmerman rotors, Dinan Stage 1 software, Strong Strut front upper stress bar.
