I sent my first analysis off and received this back. It states it's critical but doesn't show any wear metals. This sample was from a new 5L jug of Quaker State Euro 5w40. I put 1.5 jugs into my motor and this was from the 2.5L remaining in the jug. I shook the jug up before sending it in. This oil did not come from the motor of my vehicle. I'm a little confused by what they are are saying as the only ppm numbers are all green.
What's wrong with this analysis?

If I’m interpreting this correctly, what they are saying is the iron, aluminum, lead, and sodium levels are too high for new oil.
Usually see Iron & Al in new oil but the Lead not so much. Maybe ask them about re-testing it?
Just an FYI there is a new oil forum

Interesting. The last QS sample I did a VOA on also came back with iron, aluminum and lead:
Mine also had a little tin, but no sodium.
Quaker State HM FS 5W30 D1G3 VOA
Impressive viscosity and a bit overachieving compared to the 11.7 they claim on the PDS. Lots of metals in this virgin sample. Lead especially is a bit surprising. Additive package looks good but the oxidation is a bit low for a HM oil.

@FlyingTexan how did you handle the sample? I would expect to see a couple ppm of Iron and Aluminum as part of the metal deactivator chemistry, but Pb, not so much, or Na for that matter, unless sodium part of the additive package, which it isn't with this oil.
maybe they need to recalibrate their equipment? Seems odd unless the oil got contaminated somehow.
but same lab for both?
Maybe send another sample to a different lab..
While none of those elements shown will cause any damage it is concerning for people using the oil and UOA's
and why those elements are present in those quantities at all..

And they didn't green flag your Pb like they did here with the same PPM.
I would ask QS about it, maybe OA can retest? I’m not sure those numbers are high enough for condemnation or not?

It's not uncommon to have 1 or 2 ppm of metal.
Here's my suggestion ... contact the lab and ask them why they flagged it; make them explain why a VOA is "critical".

Looks like it might say, "Don't waste your money of UOAs." Just do regular oil changes.
Just opened the bottle and poured it in the cup after shaking it
For the record I don’t know anything about oil tests so since the numbers were green I wasn’t sure where the fire was.

It probably got contaminated by the lab, or there was some contaminant in the container you sent it in.
It's supposed to be the same oil as Pennzoil Platinum Euro. I wrote them back saying exactly how/when I took the oil sample and they sent back the report with the same numbers but everything green stating no issues then. This is the response I received.The fact that two different VOAs of Quaker State both had more metal than usual seems to point to Quaker State as being the source, not contamination.
Thoughts?

Actually the opposite. You'd need two VOA's from two different labs with the same oil. Both of these VOAs were from Oil Analyzers. That would tell me the issue is equally likely their testing equipment.The fact that two different VOAs of Quaker State both had more metal than usual seems to point to Quaker State as being the source, not contamination.
The only evidence is that Quaker State Ultimate Protection is their only GTL product I've seen w/pdf sheet to back it up. Platinum Euro is GTL so you would be saying This QS Euro 5w-40 is GTL. Please share your information regarding this QS Euro being the same GTL Pennzoil Euro.
A few years ago the QS Euro had the same SDS as Ultimate Protection, 70-90% GTL, but now I can't find it and I did find a different one I have now lost that said 40% GTL. I dunno.
I do know the add packs are dead ringers for each other.
