So here is the story. Bought a certified used 2010 optima from a Kia dealer. Car had 20,000 miles when I bought it.Always faithful on my oil changes. Usually using Dino, 4K intervals. Usually 5w20 , maybe 2-3 of 5w30 when Autozone had the nextgen valvoline on clearance. The pics below are of the filter cut open about 1k into an oil change. Started having a knock on deceleration, so I thought maybe filter restricting flow. Swapped a new red purolator on and the noise was back in 2 days. Cut the old filter open and you can see the fairy dust from hades in the oil. Maybe could have done crank/main bearings and unloaded it, but I think Karma is a mean mistress. Instead I bought a used engine w 60k on it and swapped it out myself. I was not happy. Anyway, thought I would share. Btw last oil change was cheap O'reilly Dino and their house filter. Makes me wonder if that may have been the culprit. (I doubt it)bottom pic is of a coffee filter I poured the oil out of the filter through and let sit a few days. Engine is the 2.4 DOHC 4 cyl.
Have a good day everyone!
