Please advise what can I use instead of Texaco ETL 8072B

I didn't realize BMW synthetic engine oil wasn't a real synthetic?!

For x-drive they spec "BMW transfer case oil - TF 0870", they don't say what it is and I never bought it. Even Mike Miller states that there is no aftermarket substitute for it, and it definitely isn't Dexron III ATF. See below.

It is basically the same for the engine oil: they have an approved list, and I am using one of the oils on that list. The Mobile 1 is a real synthetic oil, while the BMW oil is not. If I can use a better oil for the same or less money, why wouldn't I?

What oil does BMW recommend for the x-drive transfer case?

It is a matter of interpretation. It is a real synthetic according to the court cases that went on years ago. It isn't a Group IV (PAO) base stock, which some call a 'real' synthetic. To me, it is a moot point since many oils from Group III and Group IV now meet the same specs, due to improvements in processing. I think the specs are more important than the process by which the oil was processed.

It is a Group III, which in just about every other country in the world cannot legally be called a synthetic. Group III oils are pretty good, but since Group IV (real synthetic) oils are available for about the same money, I usually avoid Group III.

Here is a site with some good info on the differences:

Hello guys!
Here I am.

Finally I've changed trans. fluid
I bought Conoco Phillips Dexron VI as said before and new filter with gasket.

Well what can I say... I'm happy.
At this stage were used 7 quarts of fluid and after 300 km I'll change it again to renew.
Below is small photoreport as promised.








Below is magnet. Also as you may see there some small metal dust on it.




I washed up pallet and put magnet back...

Great post! Do you notice any difference in the way it drives? With Dexron VI, you should get a slight bump is gas mileage.
