BMW High Performance Synthetic 5w-30 VOA

[JHZR2]

This is a UOA of BMW performance synthetic 5w-30 that I got from Dan at United BMW. This is what I used in my 2011 135i N55 engine at its 1300 mile OC.

I believe this is Castrol TXT in europe. It is an ACEA A3 rated and BMW LL-01 rated oil. I do not believe that there are any other specifications listed on the bottles.

Thanks for posting.

This is a heavy 30wt oil, presumably with a HTHS vis of 3.5 cP.

That's a low TBN for a Long-Life oil IMO.

 

[JHZR2]

It's all about retention, not starting TBN...

 

[StevieC]

Yeah but still... It's kinda low...

Interesting that the TBN is that low. I would have expected more. It must have at least decent TBN retention...

 

[JHZR2]

Well it hardly lost any TBN (10th of the full OCI. So that may mean that we would only loose 3 TBN points across 13k... not bad. Of course it may not be linear. Look at how titrations work.

Will be interesting to see!

My Blackstone VOA back in April 2006 showed a TBN of 10.6.

Higher Ca content in there - perhaps that is why...

That UOA looks more like the FF in my 135i... FWIW.

Doesn't newer BMW engines call for BMW LL-04 instead of 01? Just wondering...

 

[d00df00d]

Only in Europe.

Here it's only for the newer diesels.

Still looks like a great oil.
