I would call your is probably lost. I have heard that happening several times...So why were they able to process yours in 5 days but I haven't heard anything about mine, which I sent in before yours. I hope it wasn't lost.

I believe so as I had the same thing on a PUP 0w20 test from about the same dates on another vehicle I do analysis on..the boron went down and the viscosity increased....I finally got my result today.

I'm happy to see that the wear metals are down despite the higher mileage this interval. Looks like I've cleared the last of the silicon out from assembly. And fuel dilution has continued to reduce on a per-mile basis, a sign that the rings are nearly fully broken in.
One big curiosity stands out to me. The amount of boron (friction modifier) is down 25%, and calcium (detergent) is down 10%. ZDDP (anti-wear) is also down slightly. Did Pennzoil alter their formula? Just to be sure, I shake up my oil jugs every few months, and vigorously before the oil change, to ensure the additives are all going into the engine.
I just did a 10K run on the Pennz Non-Ultra Platinum and the Boron was way low compared to the previous oils I have used. Everything was fine but WHOA that is a BIG difference in Boron from the other oils.I finally got my result today.

Mix it up thoroughly, pull your sample and let the lab know what your looking for / concerns. You could let them know the sample is from a 3 months ago oil change been sitting in a jug in case that has any bearing on their lab work.... Is it worthwhile to send a sample in? ...
blackstone said that does not matter like above poster said shake it up and let the lab know..Folks, I have a jug of used Royal Purple oil from the oil/filter change at the end of September (before the most recent one showing contamination). Is it worthwhile to send a sample in?If it comes back showing the same elevated values for potassium and sodium, then the coolant contamination is likely pre-existing. If it shows values similar to the 1/2024 sample, then I can narrow down what the culprit might be.
The jug has been sitting in the laundry room for three months.
