From Exxon-Mobil....

Question:
Does Mobil 1 Synthetic ATF Meet the Requirements for ZF Transmissions?
I have found out that Mobil is recommending the Mobil 1 Synthetic ATF as a replacement for the Esso LT 71141 ATF used in BMW transmissions. I have a 1998 BMW 750iL with a ZF 5HP30 transmission, does Mobil Oil guarantee this product as meeting all the requirements of the ZF transmission?

Answer:
No. We do not guarantee that the product meets all the requirements of ZF transmissions, which are very extensive depending on the transmission type/model year. ExxonMobil does say that this product is suitable for use in this application based on the type and quality of the recommended fluid, Esso LT 71141.


Use non-approved fluids at your own risk, seems to be the stance of the oil company

I think the correct advice is to top off the fluid using what is spec'd for the specific trans.
