All mileage is in kilometers not miles. Notes from oil slip: "Normal street use. I had to top up the oil since it was low on the dip stick. I used Red Line 15W-50 as the top-up oil since I had that handy." Previous fill was Red Line 5W-30. Next fill is 5 qts of Mobil 1 0W-40 and 1 qt of Mobil 1 15W-50 since I had those handy.
Unrelated to UOA, but I have gotten the following DTCs since Jan 2021: P0430 and P0420. The typical corrective action is to replace the catalytic converters, however I've noticed no drop in street drivability. I'm guessing they are marginal and I can keep running the cats for now. I had the exhaust system checked for leaks as well as any other obvious problems. We also tested the exhaust back-pressure and it is normal.
