HPL PCEO 5w-30 base VOA ... 2025

See attached for the base PCEO in 5w-30

NOTE >>> This VOA was in error in the barium and titanium. See post #13 below for "updated" analysis of this sample.

what does Barium do in a engine oil??

 

[Glenda W.]

Thank you. The base PCEO doesn’t disappoint!

Detergent and dispersant.

Thanks
I'm running this oil in my C5 LS1 this year.
I will post a UOA report this fall when the oil has about 10k miles on it.

Is this the same offering as:

I guess they liked something Castrol was doing (hint: Ti). Also, that sure is a lot of Silicon…both new and old versions.

Assuming these are both the “basic” PCMO, and given how “mixing oils” is considered gauche, can you mix this with 1 yr old PCMO without being criticized? Could result in some head-scratching over the resulting UOA.

This is incorrect. There's no Ti nor Ba in that oil. Have them rerun the sample.

I’d think it was more a fat-finger or transposition error rather than measurement error… does the data auto-populate from their machine or do they have to type all that stuff into the form?

My question exactly. Never heard of barium other than an enema.

That is a possibility, but many times, it's auto-populated. It depends on that lab's procedure.

The ICP looks at elements on a spectrum, the cutoff between them sometimes getting blurred, meaning you can have cross interference if not properly calibrated or the sample is scanned too quickly. That barium could be calcium or another additive element subject to interference. I would still request they rescan the sample due to abnormal results.

Looks like a lab error. Barium was abandoned due to toxicity.

"Barium was a detergent additive metal found in natural gas engine oils but is no longer allowed in products manufactured in North America due to toxicity concerns"

I'm going to request a retest of the sample (assuming they still have it around).
The Ti and barium just never made sense to me.
I will say, they don't make it easy to navigate their site and request help ...

 

[dnewton3]

Updated report; same sample was rerun on a different ICP machine per the analyst ...
note the titanium and barium seem "normal" now.
