Jeep 3.6L 20.5k mi; RL 0w-20 1.9k mi

Really appreciate all the comments. Nobody has touched my Jeep. I do everything on it. Air filter was clean and the box properly closed. Oil has been changed multiple times before. I did a UOA before and things looked normal for the mileage. I was using Pennzoil at the time.
I am starting to blame the quality of this pump. Those hoses must have been full of dirt already. Oil is too expensive to drain at such low interval so this pump was the only way.

Gotta be the pump, line, etc.

What about the high oxidation? I was expecting the viscosity to drop below 9.0 cSt after all the hard driving and heat. I should've done a VOA like suggested here.

Red Line uses a very good base oil with higher oxidation than most oils. This shows up as having a high oxidation reading but rest assured you are using a very good oil from what I've seen with RL products.

There isn't virgin oxi number posted anywhere? Always V Oxi - UOA Ox = true amount of oxidized earl.

If that much Si from dirt, Al and Fe would be increased and depending on area might see more K and Na

Maybe from New - or Si gaskets still leaching. Agree, time will tell. 100:1 it drops next OCI

Good point. I dont know how i overlooked that
