Only mobil oil that's been through ll-01 certification.
amsoil is a great example, which has oils that exceed the certification requirements, but they just don't have certifications. Their products simply state which specs the oil is compatible with.
Not every company feels good paying a 'nanny tax' to a private regulatory body - which is in no way empowered to regulate anything. Especially when it's 300'000 usd per cert + you're locked into your suppliers.
