Where have you got the info on bmw dropping their approvals? All the BMW approved oils is in the Mobil Super series nowdays.
Just the sheer amount of oils no longer carrying LL01/LL04.
I use a lot of Fuchs Titan 5w40 GT1 XTL, I was down to 5 litres so ordered another 10 as it's a great universal PCMO. The 10 litres turned up missing LL04 so I contacted Fuchs who explained the approval had expired but the formulation had not changed.
Castrol 0w30 Dexos2... Same story. Castrol has confirmed that the approval has expired and will not be renewed but the formulation is the same.
Then theres M1 0w40 FS, Castrol 0w40 A3/B4 and LL01 etc etc
I just get the feeling BMW is going for their new low HTHS "FE" oils and dumping LL01/LL04.
