ZF6 Lube - BMW ?
I know there have been many threads on this, but couldn't find them. What lube does everyone use? I've heard that BMW's lube is the best. If so, what do I ask for when I go down to the dealership? Thanks.

There are two schools of thought, that the BWM fill (Castrol TWS 10-60 - the special oil required in the M3 and M5), is too heavy for very cold conditions; or, it's perfect.
I have not had a problem with the Castrol, so I continue to use it. It's also the only other lube that has been tested for durability over the long haul, by www.zfdoc.com. Some swear by Red Line & Royal Purple oils, but I haven't used them.
ZFDoc also suggest replacing the oil every 12k miles (I just change it once a year).
you will need 3 litres, cause the tranny requires a touch more then 2 litres. The remains can be stored for the next job.
A hint - remove the fill plug FIRST. This is because if you get the drain off, and can't get the fill off... see? kinda get screwed.

The plugs are 17mm hex. You can get a set at Autozone.
Castrol TWS 10w-60 is what I use. It is excellent.
