BMW motor oil Castrol TWS 10w-60 (synthetic) BMW P/N : 07-51-0-009-420 Opinions? - ZR-1 Net Registry Forums

xlr8nflorida · 01-22-2010

I had a great conversation with TomTom72 the other day in regards to fluids in the ZR-1.

Seems like this fluid is the way to go and Bill B also seems to recommend it for the ZF-6 which in and of itself should make it a no brainer. Tom uses it with no problems whatsoever and he does a decent amount of mileage per year.

Upon researching it on several forums, it appears that there are also a bunch of guys who don't like it and question the choice. However, we all know everybody has their opinion.

I would be interested to see who all here is running the Castrol and how long you have been running it in your transmission and any issues/concerns?

Also, apparently there are others that are approved to such as the old gm stuff, the newer revised Gm fluids and apparently some others.

If you know, please post the part #s.

Thanks for your help.
