CATERHAM blend UAO ----long OCI

[MobilinHyundia]

No make up oil was added. I just took a sample to do the first UOA. No oil or filter change was done.

Im very impress by the wear number. Previous UOAs have shown higher wear.

Thanks for the VOA.
It's interesting to note that the calculated KV100 is within 0.5% of the VOA's measured figure.

I want to do another VOA on this blend to get the TBN and TAN as well.
Toromont will do the VOA with TAN and TBN.

Thanks for the updates and VOA report!!!

Question:

The latest VOA doesn't show much moly in it (81 ppm) compared to the two used oil analysis' (in the 350 ppm range) at the top of this thread.

Was the VOA from similar bottles or SN rated in comparison to the two used oil analysis?

 

[147_Grain]

Was the 0W-40 the SM version and the TGMO rated SN?

 

[MobilinHyundia]

The two used oil analysis reports : Mobil 0W40 SM and TGMO 0W20 SM.

 

[CATERHAM]

You mean the SN TGMO.

 

[MobilinHyundia]

No, the UOA reports of the oil used in my Sonata so far were all SM oils.
The current fill of the Caterham blend is: M1 SM and TGMO SN.

The VOA is M1 SM and TGMO SN.

 

[CATERHAM]

Well something is amiss because the SM TGMO had 600 ppm of moly.

No you're right, with 350 ppm in the mix the TGMO was of course SM.

 

[MobilinHyundia]

600x 3÷5= 360.

I noticed that too, nice.
