Flagged Moly and Sodium numbers - used oil analysis

[Gladiator007]

Just put AMSOIL Signature Series in the truck. Sent a sample of the unused oil for analysis and this is what I got. What's wrong with the flagged numbers?

They flagged them because the results are outside of the limits used by Oil Analyzers. Assuming that the levels are what they should be, i.e. normal for this oil, you should ignore their flags and use this as your baseline for future samples.

I am surprised they flagged Mo as while high, other oils including some Redline HP have significantly higher levels. My last virgin sample of Redline HP 10w50 was Mo 482 ppm and Na 9 ppm.

They've flagged sodium because it's unusual, but they should already have a baseline sample for AZO 0W-30 and I suspect what we are seeing is that the OP's sample doesn't match with what they have on-file for that oil (and that's likely the case for the sodium as well).

When you submit a VOA for an oil they don't have on-file, they do not flag high levels of moly:

"Flagged Moly" sure sounds like a seven-piece American Celtic Punk rock band.

I might have contaminated the oil. Sweat? I am a fat pig

I'd recommend contacting them and ask them about that (the sodium) and about the moly, as they seem to be expecting a different value from the one your sample yielded.

We have a VOA and UOA forum too...

These numbers are normal for the oil. Five samples between 2/25 and 3/26 showed Na at 5-8 ppm and Mo at 221-297. Averages are 6 ppm and 246 ppm for Na and Mo, respectively.

Then they shouldn't be flagged, this is AMSOIL's (Polaris) Oil analysis, they would have expected values for the entire AMSOIL product line, which is likely the basis for the flagging. Perhaps there's a recent formulation change and now the expected values or different? Or this is an erroneous flagging of VOA values and they accidentally compared it with the wrong product?

Just saw a voa of same oil in the voa section with 5 ppm sodium. At 6 ppm mine got flagged lol. Amsoil 0w20 has 5 ppm sodium too in a voa here

I mean there is Flogging Molly lol

Did you hear back from them? As I said, it could just be erroneous, they may have been comparing it to the wrong product reference on their end.

Will call them tomorrow

What does Sodium do anyways? Hope it doesn't cause high blood pressure, i mean high oil pressure

The sodium mostly helps with oil oxidation. Keeps oil oxidation low which is related to the TBN.
- Cleaning deposits (detergency)
- Keeping contaminants suspended (dispersancy)
- Neutralizing acids formed during combustion
- Rust/corrosion protection
- Supporting TBN (Total Base Number) reserve

It's like putting salt in something sour to make it less sour/acidic. Usually, sugar does that even better but cannot be used in a motor oil for obvious reasons.
