I believe it was a false alarm actually. I took a half dozen 50mL centrifuge tubes home from the lab, and took one sample each from the questionable oil, the filter, and three random samples from the gallon o’ oieee in my garage.
I then checked each ones optical density in a spectrophotometer, followed by centrifugation to check particulate level…they are almost IDENTICAL. I suppose it’s fine…and gearhead…I checked the plugs…and NEVER in my life have I owned a vehicle that presented such a clean plug/combustion chamber. Sweet.
