Any idea on what filter they were using?

"Titanium is a harmless oil additive" but doesn't show up in VOA? Am I reading this right?

 

[drtyler]

Titanium could be an additive in one or both of the makeup quarts or from a previous fill.

 

[alex_at]

first I thought: [censored], 55 Iron is quite above average - but then I've realised the 20.000mile OCI.

Pretty good figures fot that long OCI. Seems like a very good Oil!

 

[timeau]

Could you explain the extra amount of P and Zn in UOA comparing to VOA?
P: 954 vs 890
Zn: 1177 vs 980.

Magnesium is even "better": 441 vs 16. No, something is not accurate here.

We previously installed a Mann filter in it.

You're correct. The customer added approx 1-1/2 of another product just prior to the drain. I wish Blackstone would add a section for notes the customer added when the sample was mailed. I don't have notes here on what the customer used and can't remember.

It has to be due to the makeup oil just prior to our drain sample. I should have stated that in the OP.

This 20K miles oil looks solid.
Agree with Blackstone extending OCI further.

OK.
For example, you have 80 proof wiskey in a glass and in the bottle. You drank a half of glass and fill it again from the same bottle. Will you have 120 proof wiskey after this? Of it still be 80 proof?

 

[drtyler]

But they didn't use the same bottle. They used something else.

Exactly! So which conclusions could be done in this case? I suspect that some diesel oil was used for make up.

 

[GermanAutohaus]

I'm going to be sending another sample of 8100 Xcess in for a VOA. Here's a set of UOAs using the same oil on a somewhat similar Audi engine.
