No ceratec. I was running Valvoline VR1. Then I filled up 4 quarts with motor craft oil just so it didn’t do more damage when I was diagnosing.I was expecting more in the bottom of the drain pan given the glitter look. Have seen Ceratec look very similar in used oil with a weird cloudy/ridge look. Just minus the abundance in distinct glitter specs. Thought you said it had ceratec in it but may have that wrong.
Do you have an oil filter opener? Would be very interested to see what the pleats have collected.
And I might need to get metal shears but ya I’ll open up the filter at some point
