But what matters is the level of peroxides in the oil (>10 meq is considered “rancid” in the food industry.).
It appears to be easy to test, is critical for safety, can predict / explain pip or lumps. By testing, you can check the oil condition over time.
There have been reports of QSC oils (and others) that had no pip, becoming increasingly painful over time. If true, a clear sign of oxidation, and pip is more than an annoyance, but is causing tissue damage.

I'm sending it for GCMS testing this week but if the color is due to oxidation we may never know since Jano doesn't offer a test for that.
