2 VOA’s should there be more consistency?

This is the same oil but from two different batches. Seems to vary quite a bit to me.
Both are supposed to be a 5w30 blend. 4DBB6F1C-7FF4-4B5E-841A-11CAB6AC6CB5.jpeg 3067C68B-721A-467E-8775-AC3FB49E357F.jpeg

I don't understand the large TBN discrepancy given the Ca/Mg difference is so small.
Other than that you might think the viscosity would be controlled a bit tighter, but its fine.
This does not appear to be a recycled lubricant given the very low wear metals evidenced.
Is this a bulk jobber lube? Brand?

The elements are all in a reasonable margin of error at +/- 5% but magnesium, which is around 9.5%.

The swing in TBN is weird, the second sample seems lower than expected. I would recommend calling to retest.

Not a big deal imo as the amount of additives tend to revolve around maximums rather than minimums for the applicable rating.

They are both Cam2 from separate 55gal drums. Both have the same product code. The reason I sampled is because while using I noticed that the oil smelled odd. It had a fuel smell to it. I describe it as if they used up a drum of gasoline and refilled it with hydraulic oil. Not like motor oil at all. I opened another drum of this product and it smelled normal. So I sent samples of both and this is what came back.

How old are the drums? Maybe call the manufacturer and describe your observations to see what they say.
They have requested a sample and batch numbers. According to the tracking number they received it on the 24th last week. No works yet. I’m convinced it’s hydraulic oil. Both drums are from 2021 and are rated SP.

Was the smelly one the one that showed a lower KV100 and KV40 viscosity ? Looking at the results again the "thinner" lube has passable DP where the thicker one is marginal. So If you suspect oil contamination it would have been with a high viscosity fluid.

Yes, if you look at the lower left corner of the analysis you can see the lower viscosity sample labeled Cam2 and the higher one labeled unknown. I agree the higher sample isn’t correct.

Yeah I'd bet you are right man....

One drum had to have something else in it before maybe the motor oil was put in it.

I believe hydraulic oil does not have high levels of additives like motor oil though.

Both these samples are of motor oil.

This is Cam2 Superpromax 5w30 semi synthetic blend oil.

Both of these oils have roughly the same levels of molybdenum, boron levels, calcium, and magnesium levels are all close the test done by PQIA.
